Dab tsi yog qhov MRI scan?
Sib nqus resonance imaging tau dhau los ua ntau thiab siv ntau hauv cov tsev kho mob loj, tab sis qee cov neeg mob tseem tsis paub ntau txog nws. Cia peb nthuav tawm qhov paub tsis meej ntawm kev kuaj MRI ua ke nrog koj.
Sib Nqus Resonance Imaging (MRI) yog dab tsi?
Sib nqus resonance imaging, nyob rau hauv layman cov ntsiab lus, yog siv ib tug magnetic teb ntawm koj lub cev kom cov hydrogen nuclei nyob rau hauv koj lub cev fim cov kev taw qhia ntawm lub magnetic teb, thiab ces tshem tawm cov magnetic teb los ntes lub zog tso tawm los ntawm cov nuclei rov qab mus rau lawv. thawj lub xeev los tsim MR signals. Tom qab ntawd cov kab mob sib txawv tuaj yeem paub qhov txawv.
Puas muaj hluav taws xob hauv kev kuaj MRI?
Tsis muaj hluav taws xob. Lub hauv paus ntsiab lus ntawm magnetic resonance feem ntau yog nyob ntawm high-frequency magnetic teb generated los ntawm tam sim no excitation, uas yog txawv los ntawm lub hauv paus ntsiab lus ntawm ionizing hluav taws xob tsim los ntawm X-ray kuaj. Tam sim no, kev tshawb fawb txog kev kho mob tsis tau pom tias kev sib nqus resonance feem ntau siv hauv kev kho mob yuav muaj kev cuam tshuam tsis zoo rau tib neeg lub cev.
Dab tsi yog qhov sib txawv ntawm qhov yooj yim thiab txhim kho MRI scans?
Feem ntau hais lus, scan dawb yog ib qho kev kuaj xyuas yam tsis muaj kev txhaj tshuaj, thiab kev kuaj xyuas zoo dua yog qhov peb feem ntau hais tias yuav tsum tau txhaj tshuaj ua ntej kev tshuaj ntsuam, lub hom phiaj yog txhaj tshuaj gadolinium-muaj qhov sib txawv ntawm tus neeg sawv cev rau hauv cov hlab ntsha. Kev txhim kho scan yog ua tiav ntawm lub hauv paus ntawm lub scan dawb. Lub hom phiaj yog los sib piv cov kev hloov pauv ntawm qhov mob ua ntej thiab tom qab kev txhim kho thiab muab pov thawj ntxiv rau kev kuaj mob. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tias muaj qhov tsis ntev los no scan rau kev sib piv ua ntej qhov kev txhim kho scan.
Qhov zoo ntawm MRI yog dab tsi?
1. Qhov zoo tshaj plaws yog qhov MRI tuaj yeem paub qhov txawv ntawm cov ntaub so ntswg zoo heev. Piv txwv li: nws tuaj yeem paub qhov txawv ntawm cov nqaij mos xws li cov leeg, leeg, fascia, thiab rog, thiab tuaj yeem paub qhov txawv ntawm cov teeb meem grey thiab cov teeb meem dawb.
2. Muaj peev xwm ntawm ntau qhov kev taw qhia (xws li transverse, coronal, sagittal, tsis hloov txoj hauj lwm ntawm tus neeg soj ntsuam).
3. Multi-plane, multi-parameter imaging technology, yog li nws muaj peev xwm ua kom pom tseeb qhov chaw thiab thaj tsam ntawm qhov txhab thiab kev sib raug zoo nrog cov ntaub so ntswg thiab cov kab mob nyob ib puag ncig, kom cov kab mob tuaj yeem raug txiav txim siab. Yog li ntawd, nws muaj qhov tshwj xeeb zoo nyob rau hauv qhov zoo, thaj chaw thiab kev kuaj xyuas ntau ntawm cov kab mob.
4. Nws yog lub tshuab tsis muaj kev cuam tshuam, thiab tsis muaj kev puas tsuaj rau X-ray, thiab nws yeej zam lwm yam kev kuaj xyuas, xws li X-ray lossis radionuclide scanning imaging thiab lwm yam hluav taws xob puas tsuaj rau tib neeg lub cev.
Cov kab mob dab tsi yog MRIs tsim nyog rau kev kuaj xyuas?
Lub taub hau: qog, kab mob vascular (infarction, hemorrhage), o, trauma, kev loj hlob malformation, dawb teeb meem lesion, thiab lwm yam.
Caj Dab: Ntau yam benign thiab malignant qog ntawm caj dab.
Lub hauv siab: cov qog nqaij hlav hauv nruab nrab, lub plawv thiab cov hlab ntsha loj, thiab lwm yam.
Mob plab: mob qog nqaij hlav, hemangiomas, cysts, inflammatory lesions, pancreatic hlav, mob raum, cysts, qog adrenal, splenomegaly, thiab lwm yam.
Pelvic kab noj hniav: zes qe menyuam, qog ntawm zes qe menyuam, endometriosis, uterine fibroids, uterine cancer, benign prostatic hyperplasia, prostate cancer, seminal vesicle lesions, zais zis hlav, thiab lwm yam.
Pob txha caj qaum: txha caj qaum, herniated intervertebral disc, intraspinal qog, tus txha caj qaum, tus txha caj qaum kev loj hlob deformity, tus txha caj qaum o, vertebral lub cev qog, vertebral lub cev inflammatory kab mob, thiab lwm yam.
Ntsig thiab pob qij txha: meniscus raug mob, leeg raug mob, sib koom ua ke effusion, pob txha qog, avascular necrosis ntawm lub taub hau femoral, kab mob osteoinflammatory, nqaij hlav, thiab lwm yam.
Cov kev ceev faj rau kev kuaj MRI yog dab tsi?
1. Chav tsev hlau nplaum yog ib puag ncig muaj zog sib nqus. Txhawm rau ua kom muaj kev nyab xeeb ntawm tus kheej, cov neeg mob (xws li cov neeg hauv tsev neeg) uas nruab lossis nqa cov khoom thiab cov khoom siv hauv qab no hauv lub cev tsis tuaj yeem nkag mus rau hauv chav hlau nplaum: lub plawv pacemaker, defibrillator, dag lub plawv valve, aneurysm phais hlau clips, txhua yam khoom siv hluav taws xob cog rau hauv. lub cev, hlau sutures, hnov pob ntseg, cochlear implants, insulin twj tso kua mis, gastric tube tsis zoo siab lub thawv, tshem tau hniav hniav, sab hauv shrapnel los yog hlau xuab zeb, thiab lwm yam.
2. Tsis pub dhau tsib meters nyob ib ncig ntawm lub tshuab MRI, muaj cov hlau nplaum muaj zog. Cov neeg mob thiab cov neeg hauv tsev neeg raug txwv tsis pub nqa cov khoom ferromagnetic thiab cov khoom siv hluav taws xob mus rau hauv chav kuaj, xws li: watches, mobile phones, keys, lighters, npib, hair clips, tsom iav, thiab lwm yam. Lub txaj thiab lub rooj zaum log yog txwv tsis pub nkag mus hauv chav hlau nplaum. .
3. Cov neeg mob hnyav nrog claustrophobia, cev xeeb tub, tsis xis nyob, mob hnyav, kev pab lub neej thiab kev cawm tsis tuaj yeem kuaj MRI.
4. Cov neeg mob uas muaj keeb kwm ntawm kev phais thiab cov neeg mob uas muaj cov hniav cuav, tattoos, IUDs, eyeliner tattoos, thiab lwm yam yuav tsum qhia rau tus kws kho mob ua ntej kuaj.
5. Rau cov neeg mob nyob rau hauv lub caj dab, lub hauv siab, lub duav, lub plab, lub duav thiab lwm qhov chaw ntawm kev ntsuam xyuas, cov khaub ncaws nrog hlau hooks, hlau buckles, thiab zippers yuav tsum tau muab tshem tawm ua ntej, thiab nws yog advisable mus hnav khaub ncaws ua los ntawm cov paj rwb ntshiab; yoo mov rau 6 teev ua ntej kuaj MRCP, Tsis muaj dej.
6. Cov neeg mob ua npaws (lub cev kub siab tshaj 38 degrees Celsius) tsis haum rau qhov kev kuaj no.
