Lumbar MRI scan

Daim duab thaij lub lumbar magnetic resonance imaging (MRI) siv lub zog los ntawm cov hlau nplaum muaj zog los tsim cov duab ntawm qhov qis ntawm txha nraub qaum (qaum caj qaum).

MRI tsis siv hluav taws xob (x-ray).

Ib leeg MRI cov duab yog hu ua cov hlais. Cov duab tuaj yeem khaws cia rau hauv computer lossis luam tawm ntawm zaj duab xis. Ib qho kev kuaj xyuas tsim tau ntau cov duab.

Cov kev xeem muaj xws li:

• Kuaj MRI thaij me me (caj dab MRI)
• MRI

Koj yuav tau hnav khaub ncaws hauv tsev kho mob lossis khaub ncaws yam tsis muaj snaps lossis zippers (xws li cov hws lossis lub tsho loj). Nco ntsoov tias koj hle koj lub moos, hniav nyiaj hniav kub thiab nyob ua si. Qee hom hlau tuaj yeem ua rau cov duab tsaus muag.

Koj yuav tau pw saum lub rooj nqaim uas nqes mus ua ib txoj raj zoo li loj.

Qee qhov kev xeem yuav tsum muaj xim xeb tshwj xeeb (sib piv). Yuav luag txhua lub sijhawm, koj yuav tau txais qhov zas xim los ntawm txoj hlab ntsha (IV) hauv koj txhais tes lossis sab caj npab ua ntej sim. Koj tuaj yeem tau txais cov xim los ntawm kev txhaj tshuaj. Zas yuav pab cov kws ntsuas hluav taws xob pom qee thaj chaw kom pom tseeb.

Thaum lub sij hawm MRI, tus neeg siv lub tshuab yuav saib xyuas koj los ntawm lwm chav. Qhov kev kuaj mob feem ntau kav 30 mus rau 60 feeb, tab sis yuav siv sijhawm ntev dua.

Koj yuav raug hais kom tsis txhob noj lossis haus dab tsi rau 4 rau 6 teev ua ntej kev thaij.

Qhia koj tus kws kho mob yog tias koj ntshai qhov chaw kaw (muaj claustrophobia). Koj yuav tau muab tshuaj kom pab koj tsaug zog thiab tsis ntxhov siab. Koj tus kws kho mob yuav qhia ib qho MRI "qhib", hauv lub tshuab kom tsis ze ntawm lub cev.

Ua ntej sim, qhia rau koj tus kws kho mob yog tias koj muaj:

• Hlwb aneurysm txiav
• Qee yam ntawm cov khoom cua plawv tus kheej
• Lub plawv defibrillator los yog ua pa nplawm
• Pob ntseg hauv (cochlear) kev cog hniav hauv
• Kab mob hauv lub raum lossis lim ntshav (tej zaum koj yuav tsis tuaj yeem txais kev sib piv)
• Nyuam qhuav tso cov pob qij txha txuas
• Qee hom vascular stents
• Ua haujlwm nrog ntawv hlau yav dhau los (tej zaum koj yuav xav tau kev ntsuam xyuas los kuaj xyuas cov ntawv hlau hauv koj lub qhov muag)

Vim tias MRI muaj cov hlau nplaum muaj zog, cov khoom hlau tsis pub nkag mus rau hauv chav tsev nrog MRI scanner:

• Cwjmem, hnab looj tes, thiab tsom iav yuav ya hla chav.
• Cov khoom xws li cov hniav nyiaj hniav kub, watches, credit card, thiab khoom siv tau hnov ​​tau ua kom puas ntsoog.
• Pins, hairpins, hlau zippers, thiab cov khoom siv hlau zoo ib yam tuaj yeem cuam tshuam cov duab.
• Kev tshem hniav ua haujlwm yuav tsum tau coj tawm ua ntej lub scan xwb.

Kev kuaj MRI ua rau tsis muaj mob. Koj yuav xav tau dag tseem yog ntau dhau kev ua haujlwm tuaj yeem plooj MRI cov duab thiab ua rau tsis raug.

Lub rooj yuav tawv lossis txias, tab sis koj tuaj yeem thov kom pam vov lossis pam vov. Lub tshuab ua suab nrov nrov nrov thiab ua kom nrov nrov thaum muab tua. Koj tuaj yeem hnav lub pob ntseg ua kom pab tiv thaiv lub suab nrov.

Lub intercom nyob rau hauv chav tsev cia koj mus hais lus rau ib tug neeg lub sijhawm twg los tau. Qee tus MRI muaj cov TV thiab lub mloog pob ntseg tshwj xeeb uas koj tuaj yeem siv los pab lub sijhawm.

Tsis muaj lub sijhawm rov zoo li, tsuas yog koj tau muab tshuaj rau kom ib ce ntaug. Tom qab kuaj MRI, koj tuaj yeem rov qab mus rau koj li qub noj haus, ua si, thiab tshuaj.

Koj yuav tsum muaj MRI los yog koj muaj:

• Qes qis lossis mob hauv plab uas tsis zoo dua tom qab kho
• Ceg tsis muaj zog, loog, lossis lwm yam tsos mob uas tsis txhim kho lossis mob heev ntxiv

Koj tus kws kho mob kuj yuav xaj kom xa MRI yog koj muaj:

• Mob nraub qaum thiab ua npaws
• Kev yug los ntawm caj qaum qis dua
• Raug mob los yog mob mus rau tus txha nqaj qaum
• Mob qes qis thiab keeb kwm lossis cov cim qhia tias mob qog nqaij hlav
• Ntau yam sclerosis
• Teeb meem tswj hwm lossis plam koj lub zais zis
• Disk herniation

Ib qho txiaj ntsig uas niaj hnub no txhais tau tias koj lub nqaj qaum thiab cov leeg nyob ze ze ua li cas OK.

Feem ntau ntawm cov sijhawm, cov txiaj ntsig tsis meej yog vim:

• Herniated lossis "plam" disk (lumbar radiculopathy)
• Kev nqaim ntawm txha caj qaum (txha caj qaum)
• Kev ua tsis ncaj rau ntawm cov pob txha thiab pob txha mos hauv pob txha nraub qaum (spondylitis)

Lwm qhov kev ntsuas tau tsis txaus siab tuaj yeem yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Ankylosing spondylitis, uas yog hom mob caj dab
• Mob pob txha
• Cauda equina mob ntsws
• Kev poob ntawm qaum rov qab vim yog osteoporosis
• Disk o (diskitis)
• Tus txha nqaj qaum
• Mob hlwb txha caj qaum
• Cov pob txha caj qaum
• Lus hauv no teb Syringomyelia

Tham nrog koj tus kws kho mob txog koj cov lus nug thiab kev txhawj xeeb.

MRI tsis muaj hluav taws xob. Kuj tsis muaj xov xwm tshwm sim los ntawm cov kev sib nqus thiab xov tooj cua loj.

Nws tseem muaj kev nyab xeeb uas tau MRI ua thaum cev xeeb tub. Tsis muaj kev mob tshwm sim los sis cov kev mob tshwm sim tau pom.

Qhov feem ntau ntawm cov sib piv (zas xim) siv yog gadolinium. Nws muaj kev nyab xeeb heev. Ua xua rau cov xim no tsis tshua muaj. Txawm li cas los xij, gadolinium tuaj yeem tsim kev puas tsuaj rau cov neeg uas muaj teeb meem lub raum uas xav tau lim ntshav. Yog tias koj muaj teeb meem lub raum, thov qhia koj tus kws kho mob ua ntej kuaj.

Lub teb muaj zog sib nqus tsim thaum lub sij hawm MRI tuaj yeem ua rau lub plawv ceev thiab lwm yam kev cog hniav tsis ua hauj lwm zoo li. Nws kuj tseem tuaj yeem ua rau lwm cov hlau hauv koj lub cev txav lossis hloov. Vim kev nyab xeeb, thov tsis txhob nqa ib yam dab tsi uas muaj hlau rau hauv chav ntsuas scanner.
