Ukuskena kwentliziyo kwePET

Ukuskena kwentliziyo positron emission tomography (PET) luvavanyo lokucinga olusebenzisa into enemitha ye-radio ekuthiwa tracer ukukhangela isifo okanye ukungahambi kakuhle kwegazi entliziyweni.

Ngokungafaniyo nemagnetic resonance imaging (MRI) kunye necomputer tomography (CT), ebonisa ukwakheka kokuhamba kwegazi ukuya nokubuya kumalungu, ukuskena kwePET kunika ulwazi ngakumbi malunga nendlela amalungu kunye nezicubu ezisebenza ngayo.

Ukuskena kwentliziyo kwe-PET kunokufumanisa ukuba iindawo zesisipha sentliziyo zifumana igazi eloneleyo na, ukuba kukho umonakalo wentliziyo okanye izicwili ezibomvu entliziyweni, okanye ukuba kukho izinto ezininzi ezingaqhelekanga kwizihlunu zentliziyo.

Ukuskena i-PET kufuna isixa esincinci sezinto ezinemitha ye-radio (tracer).

• Le tracer inikwa ngomthambo (IV), rhoqo ngaphakathi engqinibeni yakho.
• Ihamba egazini lakho kwaye iqokelela kumalungu nakwizicubu, kubandakanya nentliziyo yakho.
• I-tracer inceda i-radiologist ibone indawo ezithile okanye izifo ngokucacileyo.

Kuya kufuneka ulinde kufutshane njengoko i-tracer ifunxwe ngumzimba wakho. Oku kuthatha malunga neyure e-1 kwiimeko ezininzi.

Emva koko, uya kulala kwitafile emxinwa, ethi ityibilike kwiskena esikhulu esimilise itonela.

• I-Electrodes ze-electrocardiogram (ECG) ziya kubekwa esifubeni sakho. Iskena se-PET sifumanisa imiqondiso evela kulandelwa umkhondo.
• Ikhompyuter itshintsha iziphumo zibe yimifanekiso emi-3-D.
• Imifanekiso iboniswe kwisohlo se-radiologist ukuba siyifunde.

Kuya kufuneka ulale uthe cwaka ngexesha lokuskena kwePET ukuze umatshini avelise imifanekiso ecacileyo yentliziyo yakho.

Ngamanye amaxesha, uvavanyo lwenziwa ngokudibeneyo novavanyo loxinzelelo (umthambo okanye uxinzelelo lwe-pharmacologic).

Uvavanyo luthatha malunga nemizuzu engama-90.

Unokucelwa ukuba ungatyi nantoni na iiyure ezi-4 ukuya kwezi-6 ngaphambi kokuskena. Uya kukwazi ukusela amanzi. Ngamanye amaxesha unokunikwa ukutya okhethekileyo ngaphambi kovavanyo.

Xelela umboneleli wakho wezempilo ukuba:

• Uyayoyika indawo ekufutshane (ine-claustrophobia). Unokunikwa iyeza lokukunceda uzive usozela kwaye ungakhathazeki kangako.
• Ukhulelwe okanye ucinga ukuba unokukhulelwa.
• Unayo nayiphi na i-aleji yedayi ejoyiweyo (umahluko).
• Uthatha i-insulin yeswekile. Uya kudinga amalungiselelo akhethekileyo.

Soloko uxelela umboneleli wakho ngamayeza owathathayo, kubandakanya nalawo athengwe ngaphandle kommiselo. Ngamanye amaxesha, amayeza anokuphazamisa iziphumo zovavanyo.

Unokuziva ubambe kabukhali xa inaliti equlathe itracer ibekwe emthanjeni wakho.

Ukuskena i-PET akubangeli zintlungu. Itafile inokuba nzima okanye ibanda, kodwa ungacela ingubo okanye umqamelo.

I-intercom egumbini ikuvumela ukuba uthethe nomntu nangaliphi na ixesha.

Akukho xesha lokufumana kwakhona, ngaphandle kokuba unikwe iyeza lokuphumla.

Ukuskena kwentliziyo kwe-PET kunokubonisa ubungakanani, imilo, isikhundla, kunye nomsebenzi wentliziyo.

Ihlala isetyenziswa xa ezinye iimvavanyo, ezinje nge-echocardiogram (ECG) kunye novavanyo loxinzelelo lwentliziyo zinganiki lwazi lwaneleyo.

Olu vavanyo lunokusetyenziselwa ukufumanisa iingxaki zentliziyo kwaye ubonise iindawo apho ukuhamba gazi kufanelekileyo kuye entliziyweni.

Izikena ezininzi zePET zinokuthathwa ngokuhamba kwexesha ukumisela ukuba uphendula njani kunyango lwesifo sentliziyo.

Ukuba uvavanyo lwakho lubandakanya ukuzivocavoca, uvavanyo oluqhelekileyo luya kuthetha ukuba ukwazi ukuzilolonga ixesha elide okanye ixesha elide kunabantu bakho abakwiminyaka yakho kunye nesini. Awunazo iimpawu okanye utshintsho kwixinzelelo lwegazi okanye i-ECG yakho ebangele inkxalabo.

Akukho ngxaki zifunyenwe kubungakanani, imilo, okanye ukusebenza kwentliziyo. Akukho ndawo apho i-radiotracer iqokelele ngokungaqhelekanga.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Imithambo yegazi
• Ukungaphumeleli kwentliziyo okanye i-cardiomyopathy

Isixa semitha esisetyenzisiweyo kwiskena se-PET sisezantsi. Imalunga nemilinganiselo efanayo yemitha kuninzi lweCT scan. Kwakhona imitha ayihlali ixesha elide emzimbeni wakho.

Abasetyhini abakhulelweyo okanye abancancisayo kufuneka bazise ababoneleli babo ngaphambi kokuba benze olu vavanyo. Iintsana neentsana ezikhulayo esibelekweni zichaphazeleka ngakumbi ziziphumo zemitha yelanga kuba amalungu azo asakhula.

Kunokwenzeka, nangona kungenakulindeleka kakhulu, ukuba ube nempendulo engavumiyo kwizinto ezinemitha yeathom. Abanye abantu baneentlungu, ukuba bomvu, okanye ukudumba kwindawo yenaliti.

Kuyenzeka ukuba ube neziphumo ezingezizo kwiskena sePET. Iswekile yegazi okanye amanqanaba e-insulin anokuchaphazela iziphumo zovavanyo kubantu abanesifo seswekile.

Uninzi lwezikena ze-PET ngoku zenziwa kunye ne-CT scan. Olu dibaniso lokudibanisa lubizwa ngokuba yi-PET / CT.
