Iskena se-PET somdlavuza webele

Ukuskena kwe-positron emission tomography (PET) ukuhlolwa kwe-imaging okusebenzisa into enemisebe (ebizwa ngokuthi i-tracer) ukubheka ukusabalala komdlavuza webele. Le tracer ingasiza ekuboneni izindawo zomdlavuza okungenzeka i-MRI noma i-CT scan ingakhombisi.

Ukuskena kwe-PET kudinga inani elincane le-radioactive material (tracer). Le tracer inikezwa ngomthambo (IV), imvamisa ingaphakathi kwendololwane yakho, noma emthanjeni omncane osesandleni sakho. I-tracer ihamba ngegazi lakho futhi iqoqe ezithweni nasezicutshini futhi inikeze isignali esiza i-radiologist ukuthi ibone izindawo ezithile noma isifo ngokusobala.

Uzodinga ukulinda eduze njengoba umzimba wakho umunca itracer. Lokhu ngokuvamile kuthatha cishe ihora elilodwa.

Ngemuva kwalokho, uzolala etafuleni elincane, elingena kuskena esikhulu esimise umhubhe. Isithwebuli se-PET sithola amasiginali anikezwa kusuka kulandelwa umkhondo. Ikhompyutha iguqula imiphumela ibe izithombe ze-3D. Izithombe zikhonjiswa kumqapha ukuze udokotela wakho azihumushe.

Kufanele ulale unganyakazi ngesikhathi sokuhlolwa. Ukunyakaza okuningi kungafiphaza izithombe futhi kudale amaphutha.

Ukuhlolwa kuthatha imizuzu engama-90.

Ukuskena okuningi kwe-PET kwenziwa kanye ne-CT scan. Lokhu kuhlanganiswa kweskena kubizwa ngePET / CT.

Ungacelwa ukuthi ungadli lutho amahora amane kuya kwayisithupha ngaphambi kokuskena. Uzokwazi ukuphuza amanzi.

Tshela umhlinzeki wakho wezempilo uma:

• Uyesaba izikhala ezivaliwe (une-claustrophobia). Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kangako.
• Ukhulelwe noma ucabanga ukuthi kungenzeka ukhulelwe.
• Uyancelisa.
• Unemizimba yokungezwani komzimba nodayi ojojowe (umehluko).
• Uphuza i-insulin yesifo sikashukela. Uzodinga ukulungiswa okukhethekile.

Hlala utshela umhlinzeki wakho ngemithi oyiphuzayo, kufaka phakathi leyo ethengwe ngaphandle kwencwadi kadokotela. Kwesinye isikhathi, imithi ingaphazamisa imiphumela yokuhlolwa.

Ungase uzizwe uluma olubukhali lapho inaliti equkethe i-tracer ifakwa emthanjeni wakho.

Ukuskena i-PET akubangeli ubuhlungu. Igumbi netafula kungahle kubande, kepha ungacela ingubo noma umcamelo.

I-intercom egumbini ikuvumela ukuba ukhulume nomuntu nganoma yisiphi isikhathi.

Asikho isikhathi sokululama, ngaphandle kokuthi unikwe umuthi wokuphumula.

Ukuskena kwe-PET kuvame ukusetshenziswa lapho ezinye izivivinyo, ezinjenge-MRI scan noma i-CT scan, UNGANIKEZI ngemininingwane eyanele noma odokotela bafuna ukusakazeka okungaba khona komdlavuza webele kuma-lymph node noma ngaphezulu.

Uma unomdlavuza webele, udokotela wakho angayalela lokhu kuskena:

• Kungekudala ngemuva kokuxilongwa kwakho ukuze ubone ukuthi umdlavuza ususakazekile yini
• Ngemuva kokwelashwa uma kunokukhathazeka ukuthi umdlavuza ubuyile
• Ngesikhathi sokwelashwa ukubona ukuthi umdlavuza uyasabela yini ekwelashweni

Ukuskena kwe-PET akusetshenziselwa ukuhlola, noma ukuxilonga, umdlavuza webele.

Umphumela ojwayelekile usho ukuthi azikho izindawo ezingaphandle kwesifuba lapho i-radiotracer iqoqwe ngokungajwayelekile. Lo mphumela kungenzeka ukuthi usho ukuthi umdlavuza webele awusakazekanga kwezinye izingxenye zomzimba.

Izindawo ezincane kakhulu zomdlavuza webele kungenzeka zingaveli kuskena se-PET.

Imiphumela engajwayelekile ingasho ukuthi umdlavuza webele kungenzeka usabalale ngaphandle kwebele.

Ushukela wegazi noma izinga le-insulin lingathinta imiphumela yokuhlolwa kubantu abanesifo sikashukela.

Inani lemisebe esetshenziswe kuskena se-PET liphansi. Cishe icishe ifane nemisebe njengasezikhungweni eziningi ze-CT. Futhi, imisebe ayihlali isikhathi eside emzimbeni wakho.

Abesifazane abakhulelwe noma abancelisayo kufanele bazise odokotela babo ngaphambi kokwenza lokhu kuhlolwa. Izinsana nezinsana ezikhulayo esibelethweni zizwela kakhulu emiphumeleni yemisebe ngoba izitho zazo zisakhula.

Kungenzeka, yize kungenzeki neze, ukuthi kube nokungezwani nezinto zomzimba ezikhipha imisebe. Abanye abantu banezinhlungu, ubomvu, noma ukuvuvukala endaweni yomjovo.

Ngemuva kokuthi kwenziwe ukuskena, ungacelwa ukuthi uphuze amanzi amaningi futhi uhlale kude nezingane ezingaphansi kweminyaka engu-13 noma ngubani okhulelwe amahora angama-24.

Uma uncelisa, tshela udokotela wakho. Udokotela wakho angancoma ukuthi ungancelisi ibele amahora angama-24 ngemuva kokuskena.
