Matawai CT (Tomography Rorohiko): Ngā Whakamahinga, Te Whakarite, Te Haumaru me Ngā Mea Ka Taea, Ngā Mea Kāore e Taea te Whakaatu

Take take

• He whakamātautau motuhake te CT ki tētahi raruraru. Ka whiriwhiria te kawa matawai, te rohe tinana me te whakamahinga o te rerekētanga mō te pātai haumanu e pātaihia ana.
• Ka whakamahia e te CT te irahiko whakakāto. Ko te horopeta ka whakawhirinaki ki te rohe i matawaihia, te maha o ngā wāhanga me te matawai; he mea nui te whakamārama me te arotau i te horopeta, inā koa mō ngā tamariki me te matawai anō.
• Ahakoa he CT noa, ehara i te mea kāore he hē. Ka ngaro pea i te CT te mate i te wā tōmua, i te mate rānei kāore i te hanganga, ā, ko ētahi mate me whai MRI, ultrasound, endoscopy, whakamātautau toto rānei hei utu.
• Ka whakarerekē te rerekētanga o te mea ka kitea e te CT. Mā te whakamahi i te rongoā ā-uaua me te iodine ka āwhina i te aromatawai i ngā oko toto, ngā pukupuku, te mate me te mumura, engari kāore e whakamahia mō ia rangahau, ā, he whakaaro anō hoki tōna.
• He mea motuhake ki ia wae ngā ture whakarite. He rerekē ngā wā nohopuku, ngā tikanga whakataurite me ngā tohutohu mō te wā whakarite i waenga i ngā hōhipera me ngā matawai, ko ngā tohutohu tuhituhi a tō wāhanga whakaahua te mea nui.

I te titiro

E mohiotia ano ko

• Matawai CT, tomography rorohiko
• Matawai CAT (tomography axial rorohiko, he kupu tawhito)
• CT puku, CT uma, CT roro, CT KUB, CT angiography (ngā ingoa motuhake mō te rohe e whakamahia ana i runga i ngā rongoā i Inia)
• "City scan", he kupu tino rongonui i roto i ngā tari hauora o Īnia
• He rerekē ngā whakamātautau sonography, MRI me CT, ahakoa e kiia whānuitia ana ēnei whakamātautau e toru ko te "scan" i roto i te kōrero o ia rā.

He aha te matawai CT

I te wā o te matawai CT, ka huri te ngongo hihi-X huri noa i te tinana i te wā e neke ana te tēpu i roto i te matawai. Ka hurihia e te rorohiko ngā mano tini o ngā inenga ki ngā poro angiangi, ka taea e te tohunga hihi-X te arotake i roto i tētahi papa, ā, ki te whai hua, hei hanga anō toru-ahu.

Ki te whakatauritea ki te hihi-X noa, ka wehewehea e te CT ngā hanganga e taupatupatu ana, ā, ka whakaaturia ngā kiko ngohengohe, te ngako, te wai, te toto, te wheua me te whakapūpūtanga me ngā taipitopito nui atu. Ka tere te tango raraunga a ngā matawai hou, ā, ka whai hua te CT ina mate te tūroro, ina mamae, ina kore e taea te takoto roa, ina kore rānei e taea te noho marino.

Ehara te CT i te whakamātautau kotahi. He rerekē ngā tautuhinga, he rerekē ngā whakataunga rerekē mō te whakamātautau CT mō te mate whatukuhu, he rerekē hoki ngā horopeta irahiko e whakamahia ana mō te CT KUB mō te whakapae he mate whatukuhu, he rerekē hoki te angiogram pūkahukahu CT mō te whakapae he mate pūkahukahu, me te CT roro noa mō te whakapae he whiu. Mā te tono i te tikanga hē ka puta he matawai noa iho, kāore e whakautu i te pātai haumanu.

He aha i mahia ai he matawai CT

• Te aitua: te aromatawai i te whara o te mahunga, te whara o te uma me te puku, me te whakapae he toto o roto, he whati rānei.
• Ngā tohu roro tere: Ko te CT roro noa te whakamātautau whakaahua tuatahi i te wā e whakapaetia ana he whiu ohorere, ko te nuinga hei tautuhi i te toto me te ārahi i ngā whakatau maimoatanga wawe tonu.
• Ngā raruraru o te uma: te whakaahua i ngā atarangi o te pukahukahu e kitea ana i te hihi-X, te aromatawai i te mate pukahukahu interstitial, te niumōnia uaua, me te whakapae he pulmonary embolism (me te whakamahi i te rongoā ārai mate).
• Te mamae o te puku me te hope: te whakapae mō te apendicitis, te diverticulitis, te aukati whekau, te whēwhe, ngā raruraru pancreatitis me ngā kohatu mimi.
• Te tiaki i te mate pukupuku: te kimi i te puku, te aromatawai i te horapa, te whakarite pokanga, te radiotherapy rānei, me te aroturuki i te urupare ki te maimoatanga.
• Aromatawai toto: Ko te angiography CT mō te aneurysm, te tapahi rānei o te aorta, me te mate o te uaua.
• Aratohu tukanga: Ko te koiora e arahina ana e te CT me te tango i ngā kohinga.
• Ngā taipitopito o te wheua me te hononga: ngā whati uaua, ngawari rānei, kāore e mārama ki te hihi-X.

Ko wai me whiwhi i tēnei whakamātautau

He tika te CT ina whakatau te tākuta e rongoā ana ka huri te whakahaere i ngā mōhiohio kua riro mai, ā, ina hoki e tika ana te pātai haumanu mō te whakaahua whakawhiti-wāhanga e ahu mai ana i te hihi-X. I te nuinga o te wā, ka whakaarohia te CT mō:

• Ngā tāngata kua whara nui, inā koa te mahunga, te uma, te puku, te tuaiwi rānei.
• Ngā pakeke e ngoikore ohorere ana, e piko ana te kanohi, e kore e mārama te kōrero, e ānini ohorere ana rānei, ina hiahiatia he whakaahua roro tere.
• Ngā tūroro e mamae nui ana te puku, e kore rānei e taea te whakamārama, ina whakapaetia he take hanganga.
• Ko ngā pakeke e mamae nui ana te taha kotahi e tohu ana he kohatu mimi kei roto, e whakamahia pinepine ana te CT KUB iti-horopeta kore-whakawhiti mō ngā pakeke kāore i te hapū.
• Ko te hunga he rerekē te ahua o te hihi-X o te uma, he maremare tonu me ngā āhuatanga āwangawanga, he whakapae rānei kei te pāngia rātou e te pulmonary embolism.
• Ngā tūroro kei raro i te maimoatanga matepukupuku me hiahia kia tirohia te āhua o te mate i ngā wā kua whakaritea e te tīma oncology.

Ehara i te mea ko te CT te taahiraa tuatahi tika mō: te tirotiro auau i tētahi tangata hauora kāore he tohu, kāore hoki he aromatawai mōrearea; te nuinga o ngā raruraru o te turi, te pakihiwi, te taurakira rānei (he pai ake te MRI); te aromatawai tuatahi o te puku hāpu, o te puku tamariki rānei ina pai ake te whakamahi i te ultrasound; ngā puku tairoi, te ū rānei; me te nuinga o ngā tohu o te pūkahukahu, ina ko te ultrasound te whakamātautau tuatahi. He rerekē ngā hua i runga i ngā āhuatanga haumanu takitahi.

Ngā mea kāore e taea te kite, te ārai rānei i te matawai CT

He taipitopito te CT, engari kāore i te whānui. Mā te mārama ki ōna wāhi matapo ka ārai i te whakamanawa teka.

• Kāore te CT noa e tohu i te mate. Ko te tikanga o te kupu "Kāore he rerekētanga i kitea" kāore he rerekētanga i kitea i runga i aua whakaahua me taua tikanga. Kāore i rite ki te kupu "i whakakorehia".
• Te whiu ischaemic wawe. Ahakoa kei te whanake te infarct i roto i te roro, ka kitea pea he āhua noa te CT roro i muri tata mai i te tīmatanga o ngā tohu. Ko te tikanga o te CT he kite i te toto me ētahi atu kitenga tere; he tairongo ake te MRI mō ngā infarct wawe, iti rānei, me ngā whiu tohanga toto o muri.
• Ngā taipitopito o te kiko ngohengohe me te kiriuhi. Kāore i te tino pai te CT mō ngā hononga, ngā menisci, te kiriuhi, te taurakira, te pupuhi o te hinu wheua me te nuinga o ngā mate o te roro. He pai ake te MRI mō ēnei.
• Te mate o te kiriuhi mucous. Kāore te CT e whakakapi i te endoscopy, te colonoscopy rānei. Kāore e kitea ngā whara wawe o te puku, te esophageal, te colon mucosal rānei i te CT.
• Te mate o te uaua koronari me te mahi a te ngakau. Kāore te CT uma auau e aromatawai i ngā uaua coronary, i te mahi rānei o te ngākau. Ka aromatawaihia e te CT angiography coronary motuhake te hanganga me te stenosis engari kāore e aromatawai i te hiranga o te mahi o te whaiti; ka taea e te nui o te calcification, te tere o te ngākau koretake rānei te whakaiti i te rangahau. Kāore te CT uma noa e ārai i te angina.
• Mahi me te hanganga. E whakaatu ana te CT i te hanganga tinana, ehara i te mahi a ngā okana. Me whai whakamātautau toto, whakamātautau mimi, whakamātautau mahi pūkahukahu rānei ki te mahi a ngā whatukuhu, ate, pūkahukahu rānei.
• Ngā whara iti, papatahi rānei. Kāore pea e kitea ngā whara kei raro iho i te taumira o te rangahau, me te kore rānei he rerekētanga matotoru mai i te kiko e karapoti ana. Tērā pea ka ngaro i ngā rangahau kore-whakawhitinga ngā whara ka kitea noa i muri i te whakatauritenga.
• Te take o tētahi kitenga. Ka taea e te CT te whakaatu i tētahi puranga, he pūngāwerewere, he pūngāwerewere lymph, he kohinga rānei, engari he maha ngā wā kāore e taea te kī mēnā he mate pukupuku, he mate pāwera, he mate kohi, he mea kino rānei. He maha ngā wā e hiahiatia ana he koiora, he ahurea, he whakamātautau anō rānei.
• Te mamae kāore he take hanganga. He maha ngā raruraru noa, pērā i ngā mate puku mahi, te migraines, te nuinga o ngā mamae uaua me ngā wheua, te mamae neuropathic, he rite tonu te āhua o ngā matawai CT.

Ki te mau tonu ō tohumate, ki te kino haere, ki te rerekē rānei ahakoa te pūrongo CT noa, hoki atu ki te tākuta nāna i tono te matawai. Kāore te hua noa e mutu ai te aromatawai.

Ngā whakamātautau e pā ana engari he rerekē

He rerekē ngā pātai ka whakautua e ēnei whakamātautau. Kāore he mea e pai ake ana i te katoa. Ko tēhea te mea tuatahi, kei te āhua o te whakaaturanga, hei tauira, ko te mamae o te puku matau o runga e kī ana ko ngā kōhatu he mea tīmata mā te ultrasound, ko te ānini ohorere kino he mea tīmata mā te CT roro noa, ā, ko te mau o te turi i muri i te takahuri he mea hiahia kia MRI kaua ki te CT.

Me pehea te whakarite

Ko te whakarite e whakawhirinaki ana ki te rohe o te tinana, te tikanga me te whakaritenga o te whakataurite. He rerekē ēnei take whakahaere i waenga i ngā hōhipera me ngā matawai. Whāia ngā tohutohu ā-tuhi, ā-waha rānei mai i te wāhanga e mahi ana i tō matawai; ko aua tohutohu te mea nui rawa atu i ngā aratohu whānui i konei.

• Kawea ō pepa: te puka whakahaunga, te puka tono rānei, ngā matawai me ngā pūrongo o mua, me te rārangi o ō rongoā o nāianei.
• Kōrero atu ki te waeine i mua i te wā Mena kua pāngia koe e te uruparenga ki te rongoā whakakākano i roto i te iodine i mua, he mate huango tōu, he mate tākihi, he mate tairoi, he mate myeloma rānei, kei te hapu koe, kei te whakaaro rānei kei te hapu koe, kei te whāngai u rānei.
• nohopuku: Ko ētahi tikanga puku whakarei ake i te rerekētanga he wā nohopuku; he maha ngā matawai kore-whakarerekētanga, pērā i te CT roro noa, kāore e hiahiatia he nohopuku. Pātai atu ki tō tari he aha te mea e tika ana mō tō matawai.
• Te rerekētanga ā-waha: Mō ētahi rangahau puku, ka tonoa pea koe kia inu i tētahi otinga rerekē mō tētahi wā kua whakaritea i mua i te matawai. Ka roa ake te wā e whakaritea ai.
• Nga whakamātautau toto: Tērā pea ka tonoa he whakamātautau mahi tākihi tata nei (te creatinine toto, te eGFR rānei) i mua i te werohanga i te rerekētanga ā-uaua, inā koa mō ngā kaumātua, te hunga mate huka, te mate tākihi, te hunga rānei e tango ana i ētahi rongoā.
• Ngā kākahu me ngā mea whakarewa: Tērā pea ka tonoa koe kia whakawhiti ki tētahi kākahu, ka tango atu hoki i ngā whakapaipai, i ngā pine makawe, i ngā mōhiti kanohi, i ngā niho rūpahu, i ngā taputapu whakarongo me ngā mea whakarewa katoa e tata ana ki te wāhi matawai.
• Kawea mai tētahi ki a koe mēnā kei te whakamaheretia he rongoā whakamoe, mēnā rānei kei te mate koe, kei te hē rānei tō tū.

Mena kei te hapu koe, kei te hapu pea rānei

Kōrero atu ki te kaiwhakaahua irahiko me te tohunga hihi-X i mua i te matawai. Kei roto i te CT te hihi-X, ā, mō te nuinga o ngā pātai i te wā e hapu ana, he pai ake te whakamahi i te ultrasound, te MRI rānei. Kāore e rāhuitia te CT i te wā e hapu ana, i roto i ngā āhuatanga kino pēnei i te whara nui, i te whakapae rānei he embolism pūkahukahu, koinei pea te whakamātautau tika, me te pupuri i te horopeta kia iti rawa. He whakatau takitahi tēnei, ā, ka mahia tahitia e tō tākuta whānau me te tohunga hihi-X. Kaua rawa e whakaaro me whakakahoretia, me mahi rānei te matawai; pātai atu.

Mena kei te u koe

He iti noa te nui o te inenga CT whai iodine ka uru ki roto i te waiū ū, ā, kāore e tino mimitihia e te puku o te pēpi. Ko te nuinga o ngā aratohu e tautoko ana i te haere tonu o te whāngai ū i muri i te inenga whai iodine. Whakaūtia ki tō tākuta e rongoā ana me te wāhanga whakaahua.

Mena he mate huka koe

Kaua e mutu, kaua e peke, kaua hoki e whakarerekē i tētahi rongoā mate huka māu ake. Kei ētahi waeine he tohutohu motuhake mō te metformin e pā ana ki te rongoā ārai mate iodine, inā koa ka heke te mahi a te whatukuhu. He rerekē ēnei tohutohu i ia waeine, i ia mahi hoki, pātai atu ki te tākuta e tohu ana i te rongoā, ki te waeine whakaahua rānei. Mēnā ka tonoa koe kia nohopuku, ā, kei te tango koe i te insulin, i te sulfonylurea rānei, pātai atu me pēhea te whakahaere i ō horopeta me te aha me mahi mēnā ka heke tō huka, ā, me kawe mai he puna huka.

Mena he mate tākihi tōu

Me aromatawai te mahi a te whatukuhu i roto i te uaua me te whakamahi i te rongoā whakahāngai iodine. Mō te hunga he tino ngoikore te mahi a te whatukuhu, ka whiriwhiri pea te tīma i tētahi tikanga kore-whakahāngai, i tētahi atu whakamātautau, i tētahi rahinga whakahāngai iti, i te tango rānei i ngā mahi wai. Mena kei te dialysis koe, me kī atu ki te wāhanga, ka taea te whakarite i te whakaritenga me ō wā dialysis.

Mena he ngoikore tō ngākau, he herenga wai rānei tōu

Me arotake ngā tohutohu katoa mō te inu wai, te inu rongoā rānei, me te whakataurite ki te herenga wai e hiahiatia ana. Kōrero atu ki te tari whakaahua me tō tākuta e rongoā ana kia taea ai te whakarerekē i te nui me te mahere wai.

tamariki

Ka mahia te CT i roto i ngā tamariki ina tino hiahiatia ngā mōhiohio, me ngā tikanga whakaiti horopeta tamariki. He pai ake te whakamahi i te ultrasound, te MRI rānei ina taea ai te whakautu i te pātai. Ka whakamahia anake te whakamoe, te whakamoe whānui rānei ina kore e taea e te tamaiti te noho puku, ā, kāore e tika ana ngā huarahi haumaru ake; ina whakamahia, me aromatawai i mua i te whakamoe, me ngā tohutohu nohopuku, me te aroturuki me te wā whakaora. Mā te whakararuraru, te aroaro o te mātua me te whakamārama tupato ka karohia te whakamoe, nā te mea he poto noa ngā wā matawai tuturu.

Nga pakeke

He uaua te takoto papatahi, te pupuri manawa, me te whakawhiti i ngā mea ki runga, ki raro hoki i te tēpu. Kōrerotia ki ngā kaimahi te uaua ki te whakarongo, te kore manawa, te mamae o te tuara, te wiri, te pōhēhē rānei kia taea ai te whakarite āwhina anō. Ka heke te mahi a te whatukuhu i te pakeketanga, ā, ka pā tēnei ki ngā whakatau i te rerekētanga o te ine.

Ngā mea ka tupu i te wā o te matawai CT

• Takiuru me te whakaaetanga: Kua whakaūtia tō tuakiri, te rohe e tonoa ana me tō hītori. Mēnā kua whakaritea he whakatauritenga, ka arotakehia te hītori mate pāwera, te mahi a te whatukuhu me ngā rongoā.
• Pūwero: Mō ngā rangahau rerekētanga, ka whakanohoia he ipu iti ki roto i te uaua, ko te nuinga i roto i te ringa.
• Whakatūnga: e takoto ana koe i runga i te tēpu, i tō tuara i te nuinga o te wā. Tērā pea ka whakamahia he whitiki, he tautoko rānei hei āwhina i a koe kia noho marino.
• Matawai: Ka neke te tēpu mā roto i te porowhita tuwhera. Ka puta ngā oro whiowhio i te matawai. Tērā pea ka rongo koe i ngā tohutohu kua tuhia kia manawa koe, kia pupuri hoki i tō manawa.
• Werohanga rerekētanga: Ina hoatu he rerekētanga, he tokomaha te hunga e rongo ana i te whero wera, i te reka konganuku, i te ahua rānei o te mimi. Ka memeha haere ēnei kare ā-roto i roto i ngā hēkona. Mēnā ka mākūkū koe, ka pupuhi te mata, te ngutu rānei, ka kore e manawa, ka whewhe, ka whakapairuaki ohorere, ka mamae rānei i te wāhi i werohia, me kōrero tonu ki ngā kaimahi.
• Te tirohanga: i muri i te whakawehewehenga, ka tonoa pea koe kia tatari mō tētahi wā poto i mua i te tangohia o te cannula.

Kia pēhea te roa o te tukanga

• Matawai tūturu: Mō ngā rangahau rohe-kotahi maha, ko te tango hihi-X tonu ka roa i roto i ngā hēkona ki raro iho i te meneti.
• Whakaritenga katoa, matawai kore-whakawhitinga: ko te nuinga o te wā e 10-20 meneti te roa, tae atu ki te whakarerekē i te kakahu, te tūnga me te tirotiro.
• Whakaritenga katoa, matawai rerekētanga: e 30-45 meneti pea te roa, e taea ai te whakapūnga, te wā werohanga, ngā wāhanga maha me te wā tirotiro poto.
• Ngā tikanga whakahāngai ā-waha: ka taea te tāpiri i te hāora, neke atu rānei, nā te mea ka tangohia te otinga i ētahi wāhanga i mua i te matawai.
• Te koiora, te tango wai rānei e ārahitia ana e te CT: he roa ake, he maha ngā wā kotahi hāora, neke atu rānei, me te whakaora anō hoki me te mātakitaki.
• Ngā tamariki kua whakamoea, kua whakamoea rānei: He poto noa te matawai, engari ko te haerenga whānui kei roto ko te aromatawai, te whakamoe me te wā whakaora.

He rerekē ngā wā tatari i te rā me te wā tuku pūrongo i waenga i ngā whare hauora, ā, e whakawhirinaki ana ki te mea he mea tere, he mea noho tūroro, he mea noa rānei te matawai. Pātai atu ki tō tari āhea me pēhea te whiwhi i te pūrongo me ngā whakaahua.

Te mārama ki tō pūrongo CT

Ko te pūrongo CT he wāhanga tikanga (te rohe kua matawaihia, te whakamahinga o te whakataurite), he wāhanga kitenga e whakaahua ana i ia okana, i ia hanganga rānei, me tētahi whakaaro, whakatau rānei e whakarāpopoto ana i te whakamaoritanga a te tohunga hihi-X me ngā taunakitanga katoa.

• Ko te āhua te mea tino nuiengari kua tuhia mō te tākuta e tuku mai ana, i roto i te horopaki o ngā mōhiohio haumanu i whakaratohia i runga i te puka tono.
• "Te kitenga tūpono" ko te tikanga i kitea tetahi mea kāore i te pā ki te take o te matawai. He maha ngā kitenga tūpono, pērā i ngā whēkau whatukuhu māmā, ngā whara ate iti, pai, me ngā kōhatu ririki kāore e ārai ana, kāore e hiahiatia he maimoatanga. Ko ētahi me whai whakaahua whai muri.
• Ehara ngā kīanga whakaahua i te tautuhi mate. Ko te "hypodense lesion", "ground-glass opacity", "fat stranding" me te "prominent lymph node" ngā whakaahuatanga o ngā āhua. Ka whakatauhia te tautuhi mā te whakakotahi i te āhua me ngā tohu, te tirotiro me ngā whakamātautau.
• He hapa ngā inenga rahi. Ahakoa he torutoru mirimita o ngā panonitanga kitea i waenga i ngā matawai, tērā pea e whakaata ana i te rerekētanga o te ine, o te tikanga rānei, ehara i te tipu tūturu, koia te take e whiriwhiria ai ngā wā whai muri.
• He mea nui te whakataurite ki ngā karapa tawhito. Kawea mai ngā whakaahua o mua; he maha ngā wā he mea whakamarie ake te pumau i roto i te wā i tērā i tētahi putanga kotahi.
• Kaua e whakamārama i a koe anō. Me pānui tahi te pūrongo CT me te tākuta nāna i tono. Mā taua tākuta e whakatau he aha te mea me mahi i muri mai, mēnā he mea anō.

Ina he te āhua o ngā hua CT

Ngā kitenga ka taea te whakapae teka, te whakanui rānei

• Te nekehanga me te mahi manawa ka taea te hanga i te āhua pōuri e rite ana ki tētahi whara, ki tētahi papa tapahi, ki tētahi mate pūkahukahu rānei.
• Ngā mea whakarewa me ngā mea hanga niho Mai i ngā tāpiringa niho, ngā prostheses, ngā topenga pokanga, ngā koiri, ngā mahi niho rānei, ka puta ai ngā rārangi e huna ana, e tohu teka ana rānei i tētahi āhua rerekē.
• Te whakapakeketanga o te kurupae me te taonga whakairo Ka taea e ngā mea e tata ana ki te wheua, inā koa i te turanga o te angaanga me te fossa o muri, te whakaata, te huna rānei i ngā whara o te roro.
• Ngā hapa wā whakataurite ka taea e ēnei te hanga i ngā oko toto noa kia āhua rerekē, te hanga rānei i ngā kiko noa kia āhua pai ake, kia āhua kore rānei e pai ake ana.
• Ko ngā āhua pai e pohehetia ana mō te mate kino: Tērā pea ka nui rawa te whakamāramatanga mō ngā pukahukahu kua hinga engari he hauora, ngā panonitanga o ngā pukahukahu mai i te takoto papatahi, te pūkahukahu kī tonu, te utaina o te paru, ngā pona lymph tauhohe rānei.

Ngā kitenga kāore pea i te kitea, kāore rānei i te tino mārama

• Matawai wawe rawa i roto i te mate: kāore pea i te kitea ngā huringa CT i te wā tōmua o te infarct, te appendicitis tōmua, te osteomyelitis tōmua, te mumura tōmua rānei.
• Kāore he rerekētanga i te wā e hiahiatia ana te rerekētanga: Kāore e kitea ētahi pukupuku, whewhe me ngā whara toto i runga i te CT kore-whakawhitinga.
• He kawa, he rohe rānei hē: Mā te rangahau e kapi ana i te hanganga hē, ki te kore rānei te wāhanga e tika ana, ka taea te hoki "noa" engari kāore e kitea te raruraru.
• He iti te ngako e karapoti ana I roto i te hunga kikokore me ngā tamariki ka whakaitihia te rerekētanga tūturu i waenga i ngā hanganga, ka uaua ake te kite i ngā kitenga ngaro.
• Te āhua o te tinana nui ka whakanui ake i te haruru o te ahua, ā, ka whakaiti i te maia ki te tautuhi mate.
• Te toharite o te rōrahi Ka taea e ngā poro matotoru te huna i ngā whara tino iti.

He take nui kia mau tonu te tirohanga haumanu ki waenganui i ngā taha e rua o te hapa. Mēnā kāore te matawai me ngā tohu e ōrite, me whakamārama tonu ngā tohu.

Ngā mōrearea me te haumaru

He rerekē ngā āhua mōrearea o ngā rangahau CT rerekē. Kāore e ōrite te mōrearea o te CT roro noa, te CT puku whakarei ake i te rerekētanga me te koiora pūkahukahu e arahina ana e te CT, ā, kaua e whakaahuatia ki te tauākī haumaru kotahi.

radiation

Ka whakamahia e te CT te hihi ionizing, ā, he nui ake te horopeta i te hihi-X noa o te rohe kotahi. Ko te horopeta e whakawhirinaki ana ki te wāhanga tinana, te maha o ngā wāhanga, te matawai me te tikanga e whakamahia ana. Mō te pakeke takitahi i matawaihia mō tētahi take haumanu mārama, ko te painga o ngā mōhiohio tātaritanga he nui ake i te mōrearea iti mō te wā roa. Ka piki ake ngā āwangawanga me te matawai anō, me ngā matawai i roto i ngā tamariki me ngā taiohi, me ngā matawai kāore i te hiahiatia i roto i te haumanu. Ngā mahi whaitake ka taea e koe te mahi: pupuri i ngā kape o ō matawai kia kore ai e whakahokia ngā rangahau, ā, pātai atu ki tō tākuta he aha ngā mea ka rerekē i te matawai.
