CT thiab MRI siv cov txheej txheem sib txawv los qhia cov khoom sib txawv - tsis tas yuav "zoo" dua li lwm qhov.
Qee qhov kev raug mob lossis cov xwm txheej tuaj yeem pom ntawm qhov muag liab qab. Lwm tus xav tau kev nkag siab tob.
Yog tias koj tus kws kho mob xav tias muaj mob xws li los ntshav sab hauv, qog nqaij hlav, lossis mob nqaij, lawv tuaj yeem xaj CT scan lossis MRI.
Kev xaiv seb puas yuav siv CT scan lossis MRI yog nyob ntawm koj tus kws kho mob, feem ntau raws li lawv xav tias lawv yuav pom.
CT thiab MRI ua haujlwm li cas? Qhov twg yog qhov zoo tshaj rau dab tsi? Cia wb mus saib ntxiv.
CT scan, luv luv rau kev suav tomography scan, ua haujlwm ua 3D X-ray tshuab. Lub CT scanner siv lub X-ray uas dhau los ntawm tus neeg mob mus rau lub ntsuas ntsuas thaum tig ib ncig ntawm tus neeg mob. Nws ntes ntau cov duab, uas lub khoos phis tawj sib sau ua ke los tsim cov duab 3D ntawm tus neeg mob. Cov duab no tuaj yeem hloov kho ntau txoj hauv kev kom tau txais kev pom sab hauv ntawm lub cev.
X-ray ib txwm tuaj yeem muab rau koj tus kws kho mob ib qho saib ntawm thaj chaw uas yog cov duab. Nws yog ib daim duab zoo li qub.
Tab sis koj tuaj yeem saib CT cov duab kom tau txais cov noog qhov muag pom ntawm thaj chaw uas tau teeb tsa. Los yog tig ib ncig saib ntawm pem hauv ntej mus rau sab nraub qaum lossis sab rau sab. Koj tuaj yeem saib ntawm txheej txheej sab nraud ntawm thaj chaw. Los yog zoom tob rau hauv ib feem ntawm lub cev uas tau duab.
CT Scan: Nws zoo li cas?
Tau txais CT scan yuav tsum yog txoj kev sai thiab tsis mob. Koj pw ntawm lub rooj uas maj mam txav ntawm lub nplhaib scanner. Nyob ntawm koj tus kws kho mob cov kev cai, koj kuj yuav xav tau cov tshuaj pleev xim rau hauv cov hlab ntsha. Txhua scan yuav siv sij hawm tsawg tshaj li ib feeb.
CT scan: nws yog dab tsi?
Vim tias CT scanners siv X-rays, lawv tuaj yeem qhia tib yam li X-rays, tab sis muaj qhov tseeb dua. X-ray yog qhov pom kev tiaj tus ntawm thaj chaw duab, thaum CT tuaj yeem muab cov duab tiav thiab qhov tob.
CT scans yog siv los saib tej yam xws li: pob txha., pob zeb, ntshav, kab mob, ntsws, mob qog noj ntshav, mob plab.
CT scans kuj siv tau los saib tej yam uas MRI tsis pom zoo, xws li lub ntsws, ntshav, thiab hnyuv.
CT scan: Muaj peev xwm txaus ntshai
Qhov kev txhawj xeeb loj tshaj plaws uas qee tus neeg muaj nrog CT scans (thiab X-rays rau qhov teeb meem ntawd) yog qhov muaj peev xwm raug hluav taws xob.
Qee cov kws tshaj lij tau hais tias ionizing hluav taws xob tawm los ntawm CT scans yuav ua rau muaj kev pheej hmoo mob qog noj ntshav hauv qee tus neeg. Tab sis qhov tseeb txaus ntshai yog sib cav. Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj tau hais tias raws li kev paub txog kev tshawb fawb tam sim no, kev pheej hmoo ntawm mob qog noj ntshav los ntawm CT hluav taws xob yog "tsis paub tseeb."
Txawm li cas los xij, vim muaj kev pheej hmoo ntawm CT hluav taws xob, cov poj niam cev xeeb tub feem ntau tsis haum rau CT scan tshwj tsis yog tias tsim nyog.
Qee zaum, cov kws kho mob tuaj yeem txiav txim siab siv MRI es tsis txhob siv CT kom txo qhov kev pheej hmoo ntawm hluav taws xob. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov neeg uas muaj kev noj qab haus huv uas xav tau ntau qhov kev ntsuas ntawm lub sijhawm ntev.
MRI
MRI stands rau magnetic resonance Imaging. Hauv luv luv, MRI siv cov hlau nplaum thiab xov tooj cua los tsim cov duab hauv koj lub cev.
Qhov tseeb txoj kev nws ua hauj lwm muaj ib tug ntev physics zaj lus qhia. Tab sis nyob rau hauv lub ntsiab lus, nws yog me ntsis zoo li no: Peb lub cev muaj dej ntau, uas yog H20. H hauv H20 sawv cev rau hydrogen. Hydrogen muaj cov protons - cov khoom siv tau zoo. Feem ntau, cov protons tig mus rau ntau qhov kev taw qhia. Tab sis thaum lawv ntsib cov hlau nplaum, ib yam li hauv lub tshuab MRI, cov protons tau rub mus rau cov hlau nplaum thiab pib ua kab.
MRI: Nws zoo li cas?
MRI yog lub tshuab tubular. Ib qho kev kuaj MRI raug siv li 30 mus rau 50 feeb, thiab koj yuav tsum nyob twj ywm thaum lub sijhawm ua haujlwm. Lub tshuab tuaj yeem ua suab nrov, thiab qee tus neeg yuav tau txais txiaj ntsig los ntawm kev hnav pob ntseg lossis siv lub mloog pob ntseg mloog suab paj nruag thaum lub sijhawm scan. Nyob ntawm koj tus kws kho mob cov kev xav tau, lawv tuaj yeem siv cov tshuaj tua kab mob hauv cov hlab ntsha.
MRI: Nws yog dab tsi?
MRI yog qhov zoo heev ntawm kev sib txawv ntawm cov ntaub so ntswg. Piv txwv li, cov kws kho mob tuaj yeem siv tag nrho lub cev CT los nrhiav cov qog. Tom qab ntawd, MRI tau ua kom nkag siab zoo dua txhua pawg pom ntawm CT.
Koj tus kws kho mob tseem tuaj yeem siv MRI txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam.
Qee cov hlab ntsha tuaj yeem pom nrog MRI, thiab koj tuaj yeem pom tias muaj kev puas tsuaj lossis mob rau cov hlab ntsha hauv qee qhov ntawm lub cev. Peb tsis tuaj yeem pom cov hlab ntsha ncaj qha ntawm CT P scan. Ntawm CT, peb tuaj yeem pom cov pob txha nyob ib ncig ntawm cov hlab ntsha lossis cov ntaub so ntswg ncig cov hlab ntsha kom pom tias lawv muaj kev cuam tshuam rau thaj chaw uas peb xav kom cov hlab ntsha. Tab sis rau kev saib ncaj qha ntawm cov hlab ntsha, MRI yog qhov kev sim zoo dua.
MRIs tsis zoo rau saib qee yam, xws li pob txha, ntshav, ntsws thiab hnyuv. Nco ntsoov tias MRI tso siab rau ib feem ntawm kev siv cov hlau nplaum los cuam tshuam cov hydrogen hauv dej hauv lub cev. Yog li ntawd, cov khoom ntom ntom zoo li lub raum pob zeb thiab pob txha tsis tshwm sim. Yuav tsis muaj ib yam dab tsi uas muaj huab cua, zoo li koj lub ntsws.
MRI: Muaj peev xwm txaus ntshai
Thaum MRI tej zaum yuav yog cov txheej txheem zoo dua los saib qee cov qauv hauv lub cev, nws tsis yog rau txhua tus.
Yog tias koj muaj qee yam hlau hauv koj lub cev, MRI ua tsis tau. Qhov no yog vim MRI yog qhov tseem ceeb ntawm cov hlau nplaum, yog li nws tuaj yeem cuam tshuam rau qee yam kev cog hniav hlau. Cov no suav nrog qee cov pacemakers, defibrillators lossis shunt khoom.
Cov hlau xws li kev hloov pauv yog feem ntau MR-kev nyab xeeb. Tab sis ua ntej tau txais MRI scan, xyuas kom koj tus kws kho mob paub txog cov hlau hauv koj lub cev.
Tsis tas li ntawd, kev kuaj MRI xav kom koj nyob twj ywm rau lub sijhawm, uas qee tus neeg tsis tuaj yeem zam. Rau lwm tus, qhov raug kaw ntawm lub tshuab MRI tuaj yeem ua rau muaj kev ntxhov siab lossis claustrophobia, uas ua rau cov duab nyuaj heev.
Puas yog ib qho zoo dua lwm tus?
CT thiab MRI tsis yog ib txwm zoo dua, nws yog ib qho teeb meem ntawm qhov koj tab tom nrhiav thiab koj ua siab ntev npaum li cas. Ntau zaus, tib neeg xav tias ib qho zoo dua li lwm tus. Tab sis nws yeej nyob ntawm seb koj tus kws kho mob cov lus nug yog dab tsi.
