CT Scan vs X-Ray
Raws li ib txoj hauv kev pom qhov chaw ntawm pathology, tib neeg ob lub qhov muag thiab cov electromagnetic spectrum ntawm pom lub teeb yog txwv. Qhov no yog vim qhov tseeb tias qee cov ntaub so ntswg tau teeb tsa hauv cov qauv uas ua rau nws nyuaj rau kev pom, xws li tob rau hauv cov qauv tseem ceeb, sib sib zog nqus mus rau impenetrable obstacles, thiab them los ntawm ib tug neurovascular pob uas ua rau nws unrecognizable. Lub hnub nyoog ntawm Roentgen muab cov thev naus laus zis kom pom los ntawm cov khoom, thiab hu ua thev naus laus zis li x ray. Kev kuaj tomography suav tau los ua kev nce qib rau x rays. Ob leeg siv qhov pom tsis pom ntawm cov electromagnetic spectrum thiab qhov no ua rau leaps thiab ciam teb rau hauv cov tshuaj ntsuam xyuas. Kev sib piv ntawm ob qho no yuav ua raws li lub cev muaj feem cuam tshuam, theem ntawm kev siv, qhov cuam tshuam ntawm kev kho mob thiab cov teeb meem cuam tshuam.
X-Ray
Los ntawm kev tshawb pom ntawm x ray thev naus laus zis, cov tshuaj kuaj mob tau mus txog qhov siab tshiab. Ntawm no cov x rays, ib daim ntawv ntawm hluav taws xob hluav taws xob kis tau los ntawm tib neeg lub cev, yuav tsum tau ntes ntawm ib zaj duab xis tshwj xeeb tom qab tib neeg. Tus nqi ntawm kev nkag mus yog nyob ntawm lub zog ntawm cov khoom yoj. Qhov no yog ib qho ntawm cov txheej txheem imaging tshaj plaws. Nws yog ib qho yooj yim mus use, kuj pheej yig, thiab yuav tsum tau ib tug tsawg tus nqi ntawm kev txawj ntse. Muaj portable versions, thiab miniaturized versions. Cov theem ntawm hluav taws xob kuj tsawg rau ib qho kev tshwm sim siv. Qhov no tuaj yeem txhim kho nrog kev siv xov tooj cua opaque khoom. Tab sis cov khoom siv x ray tsis zoo hauv nws lub peev xwm los sib txawv ntawm cov qauv, thiab feem ntau tsis muab cov ntsiab lus hais txog cov ntaub so ntswg. Txhawm rau soj ntsuam qhov sib txawv ntawm cov pob txha ntom ntom, yuav tsum muaj theem loj ntawm qhov tsis txaus. Hauv x-ray, peb tuaj yeem saib tsuas yog antero posterior thiab lateral imaging nrog rau lwm cov kev pom tshwj xeeb rau cov cheeb tsam tshwj xeeb, tab sis peb tsis tuaj yeem saib cov ntu ntu ntawm lub cev. Nrog x rays, muaj kev pheej hmoo tsawg heev ntawm kev raug hluav taws xob. Cov teeb meem yuav yog los ntawm xov tooj cua opaque cov ntaub ntawv siv, thiab vim yog ib tug mal-function x ray ntaus ntawv.
CT Scan
CT scans siv qhov kev siv zog ntawm x rays ua ke nrog kev siv tshuab computer. Ntawm no, lub zog ntawm CT scan yog li 500 npaug ntawm lub hauv siab x ray. Tus nqi ntawm lub zog nkag tuaj yeem tswj tau yooj yim heev, thiab nws kuj tseem txhim kho nrog xov tooj cua opaque dyes. Cov no yog cov khoom siv loj heev, ua rau nws nyuaj heev rau kev txav mus los. Tsis tas li ntawd, nws yog kim heev, thiab tsis muaj ntau yam dawb, thiab yuav tsum muaj kev txawj ntse los tuav lub cuab yeej. Nws yog qhov zoo heev ntawm kev sib txawv ntawm cov tawv nqaij, thiab kuj zoo ntawm kev paub txog kev hloov cov ntaub so ntswg. Cov cuab yeej no yog rotatable, ua rau nws muaj peev xwm noj ntau axial views. Qhov no ua rau muaj kev pheej hmoo ntawm hluav taws xob ntau, nrog rau kev pheej hmoo ntawm xov tooj cua opaque dyes.
Qhov txawv ntawm CT Scan thiab X-Ray yog dab tsi?
CT scans thiab x rays yog ob qho tib si siv hauv kev kos duab sab hauv lub cev, xav tau cov yeeb yaj kiab tshwj xeeb kom tau txais cov duab, thiab ob qho tib si zoo heev ntawm kev sib cais cov pob txha ntawm cov nqaij mos. Tab sis cov x rays yog portable, yooj yim ntawm kev siv, pheej yig thiab dawb muaj. Nws tsuas yog tawm me me ntawm cov hluav taws xob, thiab feem ntau tsis muaj teeb meem dab tsi. CT scans yog cov tshuab hnyav, kim, xav tau kev tshaj lij thiab tawm cov hluav taws xob siab. CT scans tuaj yeem sib txawv qhov kev hloov pauv hauv ob hom pob txha pob txha, thiab muab cov lus piav qhia dav dav ntawm cov kev hloov pauv hauv cov ntaub so ntswg. Cov khoom siv x ray tsuas tuaj yeem muab qhov tsis zoo sib txawv ntawm ob qhov nyuaj, thiab tsis muaj qhov chaw hauv cov ntaub so ntswg elaboration. CT scans tuaj yeem coj ntau qhov kev pom hauv ib qho, qhov x rays tsuas yog tuaj yeem nqa ib qho kev pom hauv qhov txwv tsis pub muaj kev pom.
