Caj npab MRI scan

Kev ntsuas caj npab MRI (sib nqus resonance) kev soj ntsuam siv cov hlau nplaum muaj zog los tsim cov duab ntawm qaum thiab sab caj npab. Qhov no suav nrog lub lauj tshib, dab teg, tes, ntiv tes, thiab cov leeg puag ncig thiab lwm cov ntaub so ntswg.

Nws tsis siv hluav taws xob (xoo hluav taws xob).

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 tau hnav khaub ncaws hauv tsev kho mob lossis khaub ncaws yam tsis muaj xaim hlau lossis txeeb khoom noj (xws li cov hws lossis lub tsho loj). Nco ntsoov tias koj hle koj lub moos, 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 loj uas zoo li lub cav thaij rau.

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. 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 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 muab cov duab ntshiab ntawm cov ntu ntawm sab caj npab uas nyuaj rau pom kom meej rau ntawm CT scans.

Koj tus kws khomob yuav hais cov lus kuaj no yog 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
• Caj npab thiab keeb kwm mob cancer
• Caj npab los yog caj dab mob tsis zoo dua nrog kev kho mob
• Kab mob pob txha (osteomyelitis)
• Mob pob txha thiab ua npaws
• Cov pob txha tawg
• Txo cov lus tsa suab lossis "txhav" txhav ntawm pob tes los yog lauj tshib sib koom tes
• Liab lossis o ntawm pob tes los yog lauj tshib pob qij txha
• Kev raug mob rau pob txha mos thiab ligaments

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

Qhov ntsuas tsis zoo yuav yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Qeb
• Bursitis ntawm lub lauj tshib lossis dab teg
• Cov pob txha tawg lossis pob txha lov
• Ganglion cyst hauv dab teg
• Kab mob hauv cov pob txha
• Ligament, leeg, lossis pob txha mos raug mob ntawm pob tes los yog lauj tshib
• Kev puas tsuaj rau cov leeg
• Txha caj qaum (avascular necrosis)
• 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 yog tias koj muaj 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 fab tshuaj rau qhov muaj cov khoom 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 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 ntawm caj npab suav nrog:

• CT scan ntawm caj npab
• Leeg xoo hluav taws xob

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.
