Iskena seVQ

isishwankathelo

Uvavanyo lwe-VQ (i-Ventilation-Perfusion) luvavanyo lokuxilonga oluvavanya ukuhamba komoya (i-ventilation) kunye nokuhamba kwegazi (i-perfusion) kwimiphunga. Olu vavanyo ludlala indima ebalulekileyo ekuxilongeni iimeko ezifana ne-pulmonary embolism (PE) okanye ezinye iziphazamiso zokuphefumla. Ibandakanya amacandelo amabini: iskeni sokuphefumla, esivavanya indlela ohamba ngayo umoya emiphungeni, kunye ne-perfusion scan, evavanya ukuhamba kwegazi kwithishu yemiphunga. Ukwahluka phakathi kwala macandelo mabini kudla ngokubonisa ukuvaleka okanye ezinye iimeko zemiphunga.

Yintoni i-VQ Scan?

Iskena seVQ sineenxalenye ezimbini:

• Iskena sokungenisa umoya: Ilinganisa indlela umoya ohamba ngayo emiphungeni usebenzisa irhasi yeradioactive ephefumlelwa sisigulana. Le scan inceda ekubhaqeni nasiphi na isithintelo sokuhamba komoya okanye ukusasazwa okungalinganiyo komoya.
• I-Perfusion Scan: Ivavanya ukuhamba kwegazi kwizicubu zemiphunga ngokutofa isixa esincinci setracer yeradioactive kumthambo. Le ndawo ichonga iindawo ezinokuhamba kwegazi okuthintelweyo okanye engekhoyo.

Ngokudibeneyo, ezi zikena zibonelela ngombono obanzi malunga nokusebenza kwemiphunga, ukunceda ukufumanisa iimeko ezimandundu ezifana ne-pulmonary embolism.

Ukubaluleka koToliko lweZiphumo zoVavanyo

Ukutolikwa kweziphumo zokuskena kwe-VQ kubalulekile ekuqondeni impilo yemiphunga:

• Iziphumo eziqhelekileyo: Bonisa ulwabiwo olulungeleleneyo lokuhamba komoya kunye nokuhamba kwegazi kuyo yonke imiphunga.
• Iziphumo ezingaqhelekanga: Bonisa ukungahambelani phakathi kokungena komoya kunye nokudumba, okunokuthi kubonise i-pulmonary embolism, usulelo lwemiphunga, okanye izifo ezingapheliyo zemiphunga.

Ezi ziphumo zikhokela amanyathelo alandelayo oxilongo kunye nonyango.

Ukusetyenziswa kwe-VQ Scan

Iskena seVQ sisetyenziselwa:

• Ukuxilongwa kwe-pulmonary embolism (PE), ngakumbi kwizigulane ezingenakukwazi ukufumana i-CT scans.
• Ukuvavanya ukusebenza kwemiphunga phambi kotyando, njengokususwa kwemiphunga.
• Ukuvavanya iimeko ezingapheliyo ezifana neCOPD okanye isifo se-lung se-interstitial.
• Ukubeka iliso kwiingxaki kwizigulane zofakelo lwemiphunga.

Ukulungiselela uVavanyo

Ulungiselelo olululo luqinisekisa iziphumo ezichanekileyo:

• Kuphephe ukutshaya kunye ne-caffeine, njengoko inokuchaphazela ukusebenza kwemiphunga.
• Yazisa ugqirha wakho malunga nayiphi na i-allergies, izifundo ze-imaging zamva nje, okanye ukuba ukhulelwe.
• Susa nabuphi na ubucwebe okanye izinto zentsimbi ukuthintela ukuphazamiseka kwisixhobo somfanekiso.

Inkqubo yoVavanyo

Ukuskena kweVQ kubandakanya amanyathelo amabini aphambili:

• Iskena sokungenisa umoya: Uya kuphefumla irhasi encinci ye-radioactive ngokusebenzisa imaski okanye umlomo. Ikhamera ye-gamma ifota imifanekiso yokuhamba komoya kwimiphunga yakho.
• I-Perfusion Scan: Itracer eneradioactive itofwa kumthambo. Ikhamera ye-gamma ithatha imifanekiso yokuhamba kwegazi emiphungeni.

Inkqubo ayihlaseli, ayinabuhlungu, kwaye ithatha imizuzu engama-30-60.

Uluhlu oluQhelekileyo kunye namaNqanaba ekuJoliswe kuwo

Iskena seVQ asiboneleli ngoluhlu lwamanani kodwa sigxile kwiziphumo zomfanekiso. Izikena eziqhelekileyo zibonisa ukuhamba komoya kunye nokuhamba kwegazi, ngelixa iindawo ezingahambelaniyo zibonisa imiba enokubakho efana namahlwili egazi okanye umonakalo wemiphunga.

Izinto ezinempembelelo kwiziphumo zovavanyo

Izinto ezininzi zinokuchaphazela iziphumo ze-VQ scan:

• Usulelo lwemiphunga lwakutsha nje okanye iimeko zokuphefumla ezifana nesifuba.
• Ukutshaya okanye ukuchanabeka kwizinto ezingcolisa indalo.
• Ukusetyenziswa kwamayeza afana ne-bronchodilators okanye i-corticosteroids.
• Ukukhulelwa okanye ukuncancisa, okunokufuna iiprothokholi ezihlengahlengisiweyo.

Ukulawula iziphumo ezingaqhelekanga

Ukuba iskeni se-VQ sibonisa izinto ezingaqhelekanga:

• I-Pulmonary Embolism: Unyango olukhawulezileyo kunye ne-anticoagulants ukunyibilika okanye ukuthintela amahlule egazi.
• Izifo zemiphunga eziNgapheliyo: Ulawulo lunokubandakanya amayeza, ukuvuselelwa kwemiphunga, okanye unyango lwe-oxygen.
• Iingqwalasela zoTyando: Uhlengahlengiso kwizicwangciso zotyando ezisekelwe kwiimbono zokusebenza kwemiphunga.

Izibonelelo ze-VQ Scan

• Sisixhobo sokuxilonga esingenabungozi kwaye sinomngcipheko ophantsi.
• Ibonelela ngemifanekiso eneenkcukacha zokuphefumla umoya kunye ne-perfusion.
• Inceda ukukhokela izicwangciso zonyango kwiimeko ezimandundu ezifana ne-pulmonary embolism.
• Inika enye indlela kwi-CT scans kwizigulana ezinokungawamkeli umzimba okanye imiba yezintso.
