La ukuskena kwenhliziyo, noma i-myocardial scintigraphy, i ukuhlolwa kwesithombe okuvumela ukuthi ubuke izinga lokuchelela kwenhliziyo by imithambo yegazi.

Lapho igazi lijikeleza kabi kule mithambo, njengalapho ivalekile noma incisha, umsipha wenhliziyo (i-myocardium) awuwutholi umoya-mpilo owanele. Lokhu kuholela ezinhlobonhlobo zezimpawu ezingase zibe zimbi kakhulu: ubuhlungu besifuba, ukuphelelwa umoya, noma isifo senhliziyo (lokhuukunganeli kwenhliziyo).

I-scintigraphy yindlela yokuthwebula ehlanganisa ukunikeza isiguli i-tracer enemisebe, esabalala emzimbeni noma ezithweni ezizohlolwa. Ngakho-ke, yisiguli "esikhipha" imisebe ezothathwa yidivayisi (ngokungafani ne-radiography, lapho imisebe ikhishwa idivayisi). I-scintigraphy yenza kube nokwenzeka ukubona ukusebenza kwezitho (hhayi nje i-morphology yazo).

Lokhu kuhlolwa kusetshenziselwa ukuxilongwa kwe-coronary artery disease.

Kulesi simo, kufana nokusebenzisa i-echocardiography (i-ultrasound yenhliziyo).

Ivumela futhi ukuthi:

• nikeza udokotela imiyalelo ngendlela inhliziyo esebenza ngayo, ikhono layo lokumpompa noma lokukhipha igazi
• ukuhlola impilo yenhliziyo ngemva a i-infarction ye-myocardial ukubona ngeso lengqondo izindawo zei-ischemia(ezincishwe umoya-mpilo) noma ukufuna lezi zindawo uma kukhona izinsoloi-angina pectoris orHeart Ukwehluleka
• hlola ubungozi bezinkinga zenhliziyo zesikhathi esizayo, isibonelo ngaphambi kokuhlinzwa, ikakhulukazi kubantu abasengozini (isifo sikashukela, umfutho wegazi ophakeme, ukubhema, njll.) futhi abangakwazi ukwenza umsebenzi we-EKG

Qaphela ukuthi izinhlobo eziningana ze-scintigraphies yenhliziyo zingenziwa ngesikhathi sokuhlolwa kwenhliziyo:

• i-myocardial perfusion scintigraphy
• I-Isotope ventriculography noma i-angiocardioscintigraphy evumelanisiwe (MUGA), ehlinzeka ngolwazi olwengeziwe mayelana nokuphuma kwenhliziyo nokumpompa.

La i-myocardial perfusion scintigraphy kwenziwa ngemva komzamo. Ngempela, ukuntuleka kokunikezwa kwegazi uma kwenzeka izinkinga ezingeni lama-coronary kubonakala ikakhulukazi phakathi nomzamo.

It is contraindicated kwabesifazane abakhulelwe noma abancelisayo. Ukuzila ukudla akudingekile, kodwa ungase welulekwe ukuthi ungadli noma yiziphi izikhuthazi (ikhofi, itiye, njll.) ngosuku lokuhlolwa.

Ngokuvamile, uzocelwa ukuthi wenze ukuhlolwa kwebhayisikili noma i-treadmill kuqala, ngaphansi kokuqondisa kukadokotela wenhliziyo. Uma lokhu kuhlolwa kuphikisana, udokotela wakho uzokujova ngomuthi oshukumisa inhliziyo njengokungathi uyajima (dipyridamole, adenosine, dobutamine).

Phakathi noma ngokushesha ngemva kokuhlolwa, umkhiqizo okhipha imisebe ebuthakathaka (i-radiotracer) ujovwa emithanjeni engalweni, enamathela ngokuqondile ezingeni lenhliziyo.

Ngokushesha ngemva komzamo, khona-ke phakathi nesigaba sokubuyisela i-15 kumaminithi we-30 ngemva kokujova i-radiotracer, uzocelwa ukuba ulale etafuleni lokuhlola, ngaphansi kwekhamera ekhethekile (ikhamera ye-scintillation) evumela ukuthi ubuke imisebe ekhishwe inhliziyo.

Ngokuya ngemiphumela yokuqala etholiwe, singase sithathe izithombe ezintsha emahoreni ama-3 kuya kwamane ngemuva kokuhlolwa kokuqala, siphumule.

I-scintigraphy yenza kube nokwenzeka ukuveza okungavamile ekunikezeni igazi enhliziyweni, kodwa futhi nokuhlola ukusebenza kwayo, ikakhulukazi phakathi nomzamo.

Ngokuya ngemiphumela, udokotela wenhliziyo uzophakamisa ukwelashwa okufanele kanye nokulandelwa ukuze kukhawulwe izingozi zenhliziyo.

Ezinye izivivinyo zingase zi-odwe.
