Ukuskena kwe-PET
Iskena se-positron emission tomography luhlobo lokuhlolwa kwe-imaging. Isebenzisa into enemisebe ebizwa nge-tracer ukubheka izifo emzimbeni.
Iskena se-positron emission tomography (PET) sikhombisa ukuthi izitho nezicubu zisebenza kanjani.
- Lokhu kuhlukile kune-MRI ne-CT scan. Lokhu kuhlolwa kukhombisa ukwakheka, nokugeleza kwegazi kuye nokubuya ezithweni.
- Kusetshenziswa imishini ehlanganisa izithombe ze-PET ne-CT, ezibizwa nge-PET / CT.
Iskena se-PET sisebenzisa inani elincane le-tracer enemisebe. I-tracer inikezwa ngomthambo (IV). Inaliti ivame ukufakwa ngaphakathi endololwaneni yakho. I-tracer ihamba ngegazi lakho futhi iqoqa ezithweni nasezicutshini. Lokhu kusiza i-radiologist ukuthi ibone izindawo ezithile ngokucace kakhudlwana.
Uzodinga ukulinda njengoba i-tracer imuncwa umzimba wakho. Lokhu kuthatha cishe ihora elilodwa.
Ngemuva kwalokho, uzolala etafuleni elincane elingena kuskena esikhulu esimise umhubhe. I-PET ithola amasiginali avela kulokho okulandela umkhondo. Ikhompyutha ishintsha amasignali aye ezithombeni ze-3D. Izithombe zikhonjiswa kumqapha wokuhlinzekwa ngumhlinzeki wakho wezempilo.
Kufanele ulale unganyakazi ngesikhathi sokuhlolwa. Ukunyakaza okuningi kungafiphaza izithombe futhi kudale amaphutha.
Ukuthi ukuhlolwa kuthatha isikhathi esingakanani kuya ngokuthi iyiphi ingxenye yomzimba eskenwa.
Ungacelwa ukuthi ungadli lutho amahora amane kuya kwayisithupha ngaphambi kokuskena. Uzokwazi ukuphuza amanzi kodwa azikho ezinye iziphuzo ezibandakanya ikhofi. Uma unesifo sikashukela, umhlinzeki wakho uzokutshela ukuthi ungathathi umuthi wakho wesifo sikashukela ngaphambi kokuhlolwa. Le mithi izophazamisa imiphumela.
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).
Hlala utshela umhlinzeki wakho ngemithi oyiphuzayo. Yazisa umhlinzeki wakho ngemithi oyithenge ngaphandle kwemithi kadokotela. Kwesinye isikhathi, imithi ingaphazamisa imiphumela yokuhlolwa.
Ungase uzizwe uluma olubukhali lapho inaliti ene-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.
Ukusetshenziswa okuvame kakhulu ukuskena i-PET kungokomdlavuza, lapho kungenziwa:
- Ukubona ukuthi umdlavuza ususabalale kangakanani. Lokhu kusiza ukukhetha indlela yokwelashwa engcono kakhulu.
- Ukuhlola ukuthi umdlavuza wakho uphendula kahle kangakanani, kungaba ngesikhathi sokwelashwa noma ngemuva kokuphela kokwelashwa.
Lokhu kuhlolwa kungasetshenziswa futhi uku:
- Hlola ukusebenza kobuchopho
- Khomba umthombo wesifo sokuwa ebuchosheni
- Khombisa izindawo lapho kunokugeleza kwegazi okuncane kuya enhliziyweni
- Thola ukuthi ngabe isisindo emaphashini akho sinomdlavuza noma asinabungozi
Umphumela ojwayelekile usho ukuthi bekungekho zinkinga ezibonwe ngosayizi, ukuma, noma ukuma kwesitho. Azikho izindawo lapho i-tracer iqoqwe ngokungajwayelekile.
Imiphumela engajwayelekile incike engxenyeni yomzimba efundwayo. Imiphumela engajwayelekile ingabangelwa:
- Umdlavuza
- Ukutheleleka
- Inkinga ngokusebenza komzimba
Inani lemisebe esetshenziswe kuskena se-PET licishe lilingane njengoba lisetshenziswe kuma-scan amaningi we-CT. Lezi ziskena zisebenzisa ama-tracers asheshayo, ngakho-ke imisebe isukile emzimbeni wakho cishe emahoreni amabili kuya kwayishumi. Ukuba nama-x-ray amaningi, ukuskena kwe-CT noma kwe-PET ngokuhamba kwesikhathi kungakhuphula ingozi yokuba nomdlavuza. Noma kunjalo, ingozi evela kunoma yikuphi ukuskena okukodwa incane. Wena nodokotela wakho kufanele nilinganise le ngozi ngezinzuzo zokuthola ukuxilongwa okulungile kwenkinga yezokwelapha.
Tshela umhlinzeki wakho ngaphambi kokwenza lokhu kuhlolwa uma ukhulelwe noma uncelisa. Izinsana nezinsana ezikhulayo esibelethweni zizwela kakhulu emisebeni ngoba izitho zazo zisakhula.
Imvamisa, abantu bangaba nokungezwani komzimba nezinto ezilandelwayo. 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.
Iningi lama-PET scan manje ayenziwa kanye ne-CT scan. Lokhu kuhlanganiswa kweskena kubizwa ngePET / CT. Lokhu kusiza ukuthola indawo ngqo yesimila.
