I-ventriculography yenyukliya

I-ventriculography yenyukliya luvavanyo olusebenzisa izixhobo ezinemitha yeathom ekuthiwa zii-tracers ukubonisa amagumbi entliziyo. Inkqubo ayisebenzi. Izixhobo azichukumisi ngqo intliziyo.

Uvavanyo lwenziwe ngelixa uphumle.

Umboneleli wokhathalelo lwempilo uya kufaka into enemitha yeathom ebizwa ngokuba yi-technetium kumthambo wakho. Le nto incamathela kwiiseli ezibomvu ze kugqithe entliziyweni.

Iiseli ezibomvu zegazi ezingaphakathi entliziyweni ezihambisa into leyo zenza umfanekiso onokuthathwa yikhamera ekhethekileyo. Ezi scanner zilanda umkhondo wezixhobo njengoko zihamba kwindawo yentliziyo. Ikhamera inexesha kunye ne-electrocardiogram. Ikhompyuter iyayilungisa imifanekiso ukuyenza ibonakale ngokungathi intliziyo iyahamba.

Unokuxelelwa ukuba ungatyi okanye usele iiyure ezininzi ngaphambi kovavanyo.

Unokuziva uva kancinci okanye ucofe xa i-IV ifakwa emthanjeni wakho. Rhoqo, umthambo engalweni uyasetyenziswa. Unokuba nengxaki yokuhlala uzolile ngexesha lovavanyo.

Uvavanyo luya kubonisa indlela igazi elimpompoza ngayo kwiindawo ezahlukeneyo zentliziyo.

Iziphumo eziqhelekileyo zibonisa ukuba ukucofa kwentliziyo kuyinto eqhelekileyo. Uvavanyo lunokujonga amandla okucinezela wentliziyo (iqhekeza lokulahla). Ixabiso eliqhelekileyo lingaphezulu kwama-50% ukuya kuma-55%.

Uvavanyo luya kujonga intshukumo yamalungu ahlukeneyo entliziyo. Ukuba elinye icala lentliziyo lihamba kakubi ngelixa ezinye zihamba kakuhle, oko kunokuthetha ukuba kubekho umonakalo kuloo nxalenye yentliziyo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ukubhloka kwimithambo yegazi (isifo semithambo yegazi)
• Isifo sentliziyo sentliziyo
• Ezinye iingxaki zentliziyo ezenza buthathaka intliziyo (ukunciphisa ukupompa umsebenzi)
• Ukuhlaselwa kwentliziyo kwangaphambili (i-myocardial infarction)

Uvavanyo lunokwenziwa kwakhona:

• Ukuchaneka kwentliziyo
• Ukumelwa yintliziyo
• Idiopathic cardiomyopathy
• I-Peripartum cardiomyopathy
• Ischemic cardiomyopathy
• Ukuvavanya ukuba iyeza lichaphazele ukusebenza kwentliziyo

Uvavanyo lwe-nyukliya lwe-imaging luphethe umngcipheko ophantsi kakhulu. Ukubonakaliswa kwiradiyoyotopu kuhambisa inani elincinci lemitha. Eli xabiso likhuselekile kubantu abangenazo iimvavanyo zokucinga zenyukliya rhoqo.

Ukucinga ngokuhlanganisa igazi; Ukuskena kwentliziyo - inyukliya; Iradionuclide ventriculography (RNV); Ukukhangelwa kwamasango amaninzi (i-MUGA); I-cardiology yenyukliya; I-Cardiomyopathy - i-ventriculography yenyukliya

• Intliziyo - umbono wangaphambili
• Uvavanyo lweMUGA
