Ukuskena kwe-Lung PET

Iskena se-lung positron emission tomography (PET) ukuhlolwa kwe-imaging. Isebenzisa into enemisebe (ebizwa ngokuthi i-tracer) ukubheka izifo emaphashini njengomdlavuza wamaphaphu.

Ngokungafani nemifanekiso yamagnetic resonance imaging (MRI) kanye ne-computed tomography (CT), eveza ukwakheka kwamaphaphu, ukuskena kwe-PET kukhombisa ukuthi amaphaphu nezicubu zawo zisebenza kanjani.

Ukuskena kwe-PET kudinga inani elincane le-tracer. I-tracer inikezwa ngomthambo (IV), imvamisa ingaphakathi kwendololwane yakho. Ihamba egazini lakho futhi iqoqele ezithweni nasezicutshini. I-tracer isiza udokotela (i-radiologist) ukubona izindawo noma izifo ezithile ngokucacile.

Uzodinga ukulinda eduze njengoba i-tracer imuncwa umzimba wakho. Lokhu ngokuvamile kuthatha cishe ihora elilodwa.

Ngemuva kwalokho, uzolala 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 kufundwe udokotela wakho.

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

Ukuhlolwa kuthatha imizuzu engama-90.

Ukuskena kwe-PET kwenziwa kanye ne-CT scan. Lokhu kungenxa yokuthi imininingwane ehlanganisiwe evela kuskena ngasinye inikeza ukuqonda okuphelele ngenkinga yezempilo. 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 eziqinile (une-claustrophobia). Unganikezwa umuthi ozokusiza uphumule futhi uzizwe ungakhathazeki kangako.
• Ukhulelwe noma ucabanga ukuthi kungenzeka ukhulelwe.
• Unemizimba yokungezwani komzimba nodayi ojojowe (umehluko).
• Uphuza i-insulin yesifo sikashukela. Uzodinga ukulungiswa okukhethekile.

Tshela umhlinzeki wakho ngemithi oyiphuzayo. Lokhu kufaka phakathi okuthengwe ngaphandle kwencwadi kadokotela. Eminye imithi ingaphazamisa 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.

Lokhu kuhlolwa kungenziwa ku:

• Siza ukubheka umdlavuza wamaphaphu, lapho okunye ukuhlolwa kwe-imaging kunganiki isithombe esicacile
• Bona ukuthi umdlavuza wamaphaphu usabalalele kwezinye izindawo zamaphaphu noma emzimbeni, lapho uthatha isinqumo sokwelapha okungcono kakhulu
• Siza ukunquma ukuthi ukukhula emaphashini (okubonwa ku-CT scan) kunomdlavuza noma cha
• Thola ukuthi ukwelashwa komdlavuza kusebenza kanjani

Umphumela ojwayelekile usho ukuthi ukuskena akubonisanga zinkinga ngosayizi, ukuma, noma ukusebenza kwamaphaphu.

Imiphumela engajwayelekile ingabangelwa:

• Umdlavuza wamaphaphu noma umdlavuza wenye indawo yomzimba osabalele emaphashini
• Ukutheleleka
• Ukuvuvukala kwamaphaphu ngenxa yezinye izimbangela

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 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. Lokhu maduzane kuyaphela.
