Lub ntsiab sib txawv ntawm CT scans thiab Txuj CiXoo hluav taws xob tshuab yog lawv cov thev naus laus zis thev naus laus zis, qib ntawm kev nthuav dav, thiab cov ntawv thov tseem ceeb. Ntawm no yog qhov sib piv ntawm ob:
1. Sib txawv cov txheej txheem sib txawv
Xoo hluav taws xob tshuab feem ntau siv ib qho nqaj ntawm x-rays mus dhau ntawm lub cev, xws li cov nqaij mos) tshwm ntsej muag dawb thiab cov leeg nqaij) tshwm sim grey \/ dub.
CT scans (khoos phis tawj
2. Cov ntsiab lus sib txawv thiab tob
Xoo hluav taws xob tshuabyog tsim nyog rau kev soj ntsuam yooj yim thiab nrawm nrawm (xws li mob hauv siab, hauv lub hauv siab, thiab lawv tau txwv tsis pub muaj cov kabmob hauv nruab nrog cev.
CT scans tuaj yeem qhia cov ncauj lus kom ntxaws hla-ntu, cov hlab ntsha, cov ntaub so mos, thiab qog. Nws tuaj yeem tshem tawm cov teeb meem sib tshooj sib tshooj thiab qhia tawm zais tsis meej.
3. Txawv Hluav Taws Xob Hluav Taws Xob
Xoo hluav taws xob tshuabCov tshuaj ntsuam xyuas hluav taws xob qis dua (piv txwv li, lub hauv siab xoo hluav taws xob ≈ 0. 1 msv, sib npaug ntawm kev ua voj voos tom qab).
CT scans muaj qhov hluav taws xob hluav taws xob siab vim muaj ntau cov duab xoo hluav taws xob (piv txwv li, hauv siab ct ≈ 7 msv, sib npaug ntawm 2 xyoos).
4. Ceev thiab thov cov xwm txheej sib txawv
Xoo hluav taws xob tshuabYog li, noj ob peb feeb ib daim duab ib zaug, thiab feem ntau siv thaum muaj xwm ceev (piv txwv li cov pob tawg, mob ntsws, thiab lwm yam.
CT scans yog qeeb qeeb (feem ntau 5-30 feeb), tab sis tuaj yeem muab cov ntaub ntawv tshawb xyuas ntau (piv txwv li, mob ntshav qab zib, stroke).
5. Tus nqi thiab kev siv tau sib txawv
Xoo hluav taws xob tshuabYog pheej yig dua thiab siv dav hauv chaw kuaj mob, chav kho mob ti tes ti taw, thiab kho hniav.
CT scans yog kim, xav tau cov cuab yeej kws tshaj lij, thiab feem ntau siv nyob hauv tsev kho mob \/ cov chaw ua haujlwm.
