Ukuskena kwe-Brain PET
Iskena se-positron emission tomography (PET) yisivivinyo sobuchopho. Isebenzisa into enemisebe ebizwa nge-tracer ukubheka izifo noma ukulimala ebuchosheni.
Ukuskena kwe-PET kukhombisa ukuthi kusebenza kanjani ubuchopho nezicubu zabo. Okunye ukuhlolwa kwe-imaging, okufana nokuhlolwa kwe-magnetic resonance imaging (MRI) kanye ne-computed tomography (CT) kuveza kuphela ukwakheka kobuchopho.
Ukuskena kwe-PET kudinga inani elincane le-radioactive material (tracer). Le tracer inikezwa ngomthambo (IV), imvamisa ingaphakathi kwendololwane yakho. Noma, uphefumula ngezinto ezinemisebe njengegesi.
I-tracer ihamba ngegazi lakho futhi iqoqa ezithweni nasezicutshini. I-tracer isiza umhlinzeki wakho wezokunakekelwa kwempilo ukuthi abone izindawo noma izifo ezithile ngokucacile.
Ulinda eduze njengoba umkhondo ubanjwa ngumzimba wakho. Lokhu ngokuvamile kuthatha cishe ihora elilodwa.
Ngemuva kwalokho, ulele etafuleni elincane, elingena kuskena esikhulu esimise umhubhe. Isithwebuli se-PET sithola amasiginali avela kulokho okulandela umkhondo. Ikhompyutha iyishintsha imiphumela ibe yizithombe ezi-3-D. Izithombe zikhonjiswa kumonitha ukuze umhlinzeki wakho azifunde.
Kufanele ulale unganyakazi ngesikhathi sokuhlolwa ukuze umshini ukwazi ukukhiqiza izithombe ezicacile zobuchopho bakho. Ungacelwa ukuthi ufunde noma ufake amagama ezinhlamvu uma imemori yakho ivivinywa.
Isivivinyo sithatha phakathi kwemizuzu engama-30 namahora ama-2.
Ungacelwa ukuthi ungadli lutho amahora amane kuya kwayisithupha ngaphambi kokuskena. Uzokwazi ukuphuza amanzi.
Tshela umhlinzeki wakho uma:
- Uyesaba izikhala eziseduze (une-claustrophobia). Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kangako.
- Ukhulelwe noma ucabanga ukuthi kungenzeka ukhulelwe.
- Unemizimba yokungezwani komzimba nodayi ojojowe (umehluko).
- Uthathe i-insulin yesifo sikashukela. Uzodinga ukulungiswa okukhethekile.
Hlala utshela umhlinzeki wakho ngemithi oyiphuzayo, kufaka phakathi leyo ethengwe ngaphandle kwemithi kadokotela. Kwesinye isikhathi, imithi iphazamisa imiphumela yokuhlolwa.
Ungase uzizwe uluma olubukhali lapho inaliti equkethe i-tracer ifakwa emthanjeni wakho.
Ukuskena i-PET akubangeli ubuhlungu. Itafula lingaba nzima noma libande, kepha ungacela ingubo noma umcamelo.
I-intercom egumbini ikuvumela ukuba ukhulume nomuntu nganoma yisiphi isikhathi.
Asikho isikhathi sokululama, ngaphandle kokuthi unikwe umuthi wokuphumula.
Ngemuva kokuhlolwa, phuza uketshezi oluningi ukuze ukhiphe i-tracer emzimbeni wakho.
Ukuskena kwe-PET kungakhombisa ubukhulu, ukwakheka, nokusebenza kwengqondo, ngakho-ke udokotela wakho angaqiniseka ukuthi isebenza ngendlela efanele futhi efanele. Isetshenziswa kakhulu lapho ezinye izivivinyo, njenge-MRI scan noma i-CT scan, zinganikeli ngemininingwane eyanele.
Lokhu kuhlolwa kungasetshenziselwa uku:
- Thola umdlavuza
- Lungiselela ukuhlinzwa isithuthwane
- Siza ukuxilonga ukuwohloka komqondo uma ezinye izivivinyo nezivivinyo zinganikeli ngemininingwane eyanele
- Tshela umehluko phakathi kwesifo se-Parkinson nezinye izinkinga zokuhamba
Kungathathwa ukuskena okuningi kwe-PET ukuthola ukuthi uphendula kahle kangakanani ekwelashweni komdlavuza noma kwesinye isifo.
Azikho izinkinga ezitholwe ngosayizi, ukuma, noma ukusebenza kwengqondo. Azikho izindawo lapho i-tracer iqoqwe ngokungajwayelekile.
Imiphumela engajwayelekile ingabangelwa:
- Isifo i-Alzheimer noma ukuwohloka komqondo
- Isimila sobuchopho noma ukusabalala komdlavuza kusuka kwenye indawo yomzimba kuya ebuchosheni
- Isithuthwane, futhi singakhomba ukuthi ukuqubuka kuqala kuphi ebuchosheni bakho
- Izinkinga zokuhamba (njengesifo seParkinson)
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 abahlinzeki 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.
Kungenzeka ube nemiphumela engamanga kuskena se-PET. Ushukela wegazi noma amazinga e-insulin angathinta imiphumela yokuhlolwa kubantu abanesifo sikashukela.
Ukuskena kwe-PET kungenziwa kanye nokuskena kwe-CT. Lokhu kuhlanganiswa kweskena kubizwa ngePET / CT.
