Mutengo neinishuwarenzi muIndia
PET yemwoyo ndeimwe yemiedzo yemifananidzo yemwoyo inodhura zvikuru muIndia, inowanzodhura zvakanyanya kupfuura echocardiogram yekushushikana kana SPECT perfusion scan. Mitengo inosiyana zvakanyanya pakati pemaguta, pakati penzvimbo dzehurumende nedzakazvimirira, uye pakati pemhando dzezvidzidzo, saka tora quotation yakanyorwa kubva kunzvimbo chaiyo usati wabhuka. Chero nhamba yakatorwa online inongoratidza chete uye haisi vimbiso.
Zvinhu zvinokanganisa mutengo:
- Tracer yakashandiswa, rubidium-82 yakagadzirwa nejenareta ichienzaniswa neN-13 ammonia yakagadzirwa necyclotron ichienzaniswa neFDG, uye kuti tracer inofanira kufamba kure zvakadii.
- Kungave chidzidzo ichi chiri chekuzorora chete, chekushushikana kwekuzorora, kana kuti chinogona kushanda nezviratidzo zviviri.
- Mutengo wemushonga wekushushikana kwemishonga.
- Kana paine chiratidzo cheCT chekuongorora kana calcium chinowedzerwa.
- Kugadzira scanner uye kana software yekuenzanisa huwandu hwemvura inoshandiswa.
- Guta, danho rechipatara uye kana scan yacho ichiitwa semurwere ari muchipatara.
- Zvimwe zvinhu zvakaita sekunyaradza, kutarisira varwere vemwoyo uye kudzokorora kutora mifananidzo.
Inishuwarenzi: makambani einishuwarenzi yehutano muIndia anowanzo bhadhara PET yemwoyo kana ichinge yataurwa nachiremba uye chikamu chekupinda kana kupihwa rubatsiro rwezuva nezuva kana rubatsiro rwekuongorora, asi kuongororwa kwevarwere vasiri muchipatara hakubatanidzwi mumitemo yakawanda yekudzivirira. Kubvumidzwa pachine nguva nechikonzero chakajeka kubva kuna chiremba wemwoyo wako kunovandudza mukana wekubvumidzwa. Tarisa manyorerwo emutemo wako chaiwo uye taura nedhipatimendi reinishuwarenzi rechipatara usati waongororwa.

Mibvunzo inowanzobvunzwa
Ko PET scan yemwoyo iri nani pane angiography here?
Hapana chimwe chazvo chiri nani; chinopindura mibvunzo yakasiyana. PET yemwoyo inoratidza kana kuyerera kweropa kuenda kutsandanyama yemwoyo kwakaderera. Angiography inoratidza maumbirwo etsinga dzemwoyo uye inobvumira kurapwa panguva imwe chete. Vanachiremba vemwoyo vanowanzo shandisa bvunzo inoshanda sePET kuti vaone kana angiography ichidikanwa zvachose.
