Iskena se-PET somhlaza wamabele

Iskena se-positron emission tomography (PET) luvavanyo lokucinga olusebenzisa into enemitha ye-radioactive (ebizwa ngokuba yi-tracer) ukukhangela ukusasazeka komhlaza wamabele. Le tracer inokunceda ekuchongeni iindawo ezinomhlaza ezinokuthi zingaboniswa yi-MRI okanye i-CT scan.

Ukuskena i-PET kufuna isixa esincinci sezinto ezinemitha ye-radio (tracer). Le tracer inikwa ngomthambo (IV), ihlala iphakathi engqinibeni, okanye kumthambo omncinci esandleni sakho. I-tracer ihamba ngegazi lakho kwaye iqokelele kumalungu nakwizicubu kwaye inike umqondiso onceda i-radiologist ibone indawo ezithile okanye isifo ngokucacileyo.

Kuya kufuneka ulinde kufutshane njengoko umzimba wakho uthatha i-tracer. Oku kuhlala kuthatha iyure enye.

Emva koko, uya kulala kwitafile emxinwa, ethi ityibilike kwiskena esikhulu esimilise itonela. Iskena se-PET sibona imiqondiso ekhutshiweyo kwitracer. Ikhompyuter iguqula iziphumo zibe yimifanekiso ye-3D. Imifanekiso iboniswe esweni kugqirha ukuba ayitolike.

Kufuneka uxoke ulele ngexesha lovavanyo. Ukuhamba kakhulu kunokuphazamisa imifanekiso kwaye kubangele iimpazamo.

Uvavanyo luthatha malunga nemizuzu engama-90.

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

Unokucelwa ukuba ungatyi nantoni na iiyure ezi-4 ukuya kwezi-6 ngaphambi kokuskena. Uya kukwazi ukusela amanzi.

Xelela umboneleli wakho wezempilo ukuba:

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

Soloko uxelela umboneleli wakho ngamayeza owasebenzisayo, 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. Igumbi kunye netafile zinokubanda, 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 i-PET kuhlala kusetyenziswa xa ezinye iimvavanyo, ezinje nge-MRI scan okanye i-CT scan, UNGABONISI ngolwazi olwaneleyo okanye oogqirha bafuna ukusasazeka komhlaza webele kwii-lymph node okanye ngaphaya koko.

Ukuba unomdlavuza webele, ugqirha unokuyalela le scan:

• Kungekudala emva kokuxilongwa kwakho ukubona ukuba umhlaza usasazekile
• Emva konyango ukuba kukho inkxalabo yokuba umhlaza ubuyile
• Ngexesha lonyango ukubona ukuba umhlaza uyaphendula na kunyango

Ukuskena i-PET akusetyenziselwa ukukhusela, okanye ukufumanisa isifo somhlaza wamabele.

Iziphumo eziqhelekileyo zithetha ukuba akukho ndawo zingaphandle kwebele apho i-radiotracer iqokelele ngokungaqhelekanga. Esi siphumo kunokwenzeka ukuba sithetha ukuba umhlaza webele awusasazekanga kwamanye amalungu omzimba.

Iindawo ezincinci kakhulu zomhlaza wamabele azinakubonakala kwiskena se-PET.

Iziphumo ezingaqhelekanga zinokuthetha ukuba umhlaza webele unokuthi usasazeke ngaphandle kwebele.

Iswekile yegazi okanye inqanaba le-insulin linokuchaphazela iziphumo zovavanyo kubantu abanesifo seswekile.

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 baxelele oogqirha babo ngaphambi kokwenza 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.

Emva kokuba ukuskena kwenziwe, unokucelwa ukuba usele amanzi amaninzi kwaye uhlale kude nabantwana abangaphantsi kweminyaka eli-13 ubudala okanye nabani na okhulelweyo iiyure ezingama-24.

Ukuba uncelisa, xelela ugqirha wakho. Ugqirha wakho unokucebisa ukuba ungancancisi iiyure ezingama-24 emva kokuskena.
