CT angiography - makamai da kafafu

CT angiography ya haɗu da CT scan tare da allurar fenti. Wannan dabarar tana iya ƙirƙirar hotunan jijiyoyin jini a hannu ko ƙafafu. CT tana tsaye ne don kyan gani.

Za ku kwanta a kan kunkuntun teburin da ke zamewa zuwa tsakiyar na'urar daukar hotan takardu na CT.

Lokacin da kake cikin na'urar daukar hotan takardu, katakon x-ray na injin yana juyawa kusa da kai. Masu sikanin zamani "karkace" zasu iya yin gwajin ba tare da tsayawa ba.

Kwamfuta tana yin hotuna da yawa na ɓangaren jikin, wanda ake kira yanka. Waɗannan hotunan ana iya adana su, duba su a kan allo, ko kuma a buga su a fim. Za'a iya ƙirƙirar samfuran ɓangaren jiki a cikin tsaka-tsaka guda uku ta hanyar ƙara yanka tare.
