Ceg MRI scan

Ceg MRI (sib nqus resonance duab) luam theej duab ntawm txhais ceg siv cov hlau nplaum khov kho los tsim duab ntawm ceg. Qhov no suav nrog pob luj taws, ko taw, thiab cov nqaij mos uas nyob ib puag ncig.

Ceg ceg MRI tseem tsim tau cov duab ntawm lub hauv caug.

MRI tsis siv duab 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.

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

Koj yuav tau pw ntawm lub rooj nqaim uas zawv zawg mus rau hauv lub qhov zoo li lub cav ntsuas.

Qee qhov kev ntsuam xyuas siv cov zas xim tshwj xeeb (sib piv). Yuav luag txhua lub sijhawm, koj yuav tau txais qhov zas xim los ntawm txoj hlab ntsha hauv koj txhais tes lossis sab tes ua ntej ntsuas. Qee zaum, cov xim zas pliav raug muab rau hauv kev sib koom ua ke. 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 cov ntawv hlau (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 tau dag tseem. Ntau dhau ntawm lub zog 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 tso cai rau koj mus hais lus rau ib tug neeg thaum twg los tau. Qee tus MRI muaj cov TV thiab lub mloog pob ntseg tshwj xeeb 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.

Qhov kev ntsuam xyuas no tau qhia cov ncauj lus kom ntxaws ntawm cov ntu ntawm txhais ceg uas nyuaj rau pom tseeb ntawm CT scans.

Koj tus kws kho mob yuav xaj kom MRI ntawm txhais ceg yog tias koj muaj:

• Ib qhov nyhav uas tuaj yeem hnov ​​ntawm kev kuaj lub cev
• Qhov txawv txav ntawm xoo hluav taws xob lossis xoo pob txha mos
• Kev yug los ntawm txhais ceg, pob taws, lossis ko taw
• Mob pob txha thiab ua npaws
• Cov pob txha tawg
• Txo cov lus taw ntawm qhov pob qij txha
• Mob, o, lossis liab ntawm ib txhais ceg
• Liab lossis o ntawm pob taws ua ke
• Mob ceg thiab keeb kwm mob cancer
• Ceg, ko taw, lossis pob taws tsis zoo dua nrog kev kho mob
• Instability ntawm koj pob luj taws thiab ko taw

Qhov tshwm sim ib txwm txhais tau tias koj txhais ceg zoo li OK.

Qhov ntsuas tsis zoo yuav yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Qeb
• Achilles tendonitis
• Mob caj dab
• Cov pob txha tawg lossis pob txha lov
• Kab mob hauv cov pob txha
• Ligament, leeg, lossis pob txha mos raug mob
• Kev puas tsuaj rau cov leeg
• Txha caj qaum (avascular necrosis)
• Plantar fascia rupture (Pom: Plantar fascitis)
• Posterior tibial tendon dysfunction
• Kua muag los sis tawg ntawm Achilles leeg nyob rau hauv lub pob taws
• Mob qog nqaij hlav los yog mob qog nqaij hlav hauv cov pob txha, cov leeg, lossis cov nqaij mos

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. Kev ua xua tau muaj tsawg tsawg. 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 ib daig hlau nyob 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.

Kev ntsuam xyuas uas yuav ua tau kom tsis txhob muaj MRI suav nrog:

• Cov pob txha scan
• CT scan ntawm txhais ceg
• Positron emission tomography (PET) scan
• Xoo hluav taws xob ntawm ceg

Kev xaj mab yuav zoo dua thaum muaj xwm ceev. Qhov ntsuas sai dua li MRI thiab feem ntau muaj nyob hauv chav xwm txheej ceev.
