Mob plab MRI scan
Kev kuaj xyuas lub ntsej muag lub ntsej muag yog ib qho kev ntsuam xyuas uas siv cov hlau nplaum muaj zog thiab xov tooj cua loj. Cov nthwv dej tsim cov duab ntawm sab hauv lub plab. Nws tsis siv hluav taws xob (xoo hluav taws xob).
Ib qho sib nqus cov duab tshav ib leeg (MRI) hu ua cov hlais. Cov duab tuaj yeem khaws rau hauv lub koos pij tawj, saib ntawm lub ntsuas, lossis luam theej duab rau lub disc. Ib qho kev xeem yuav tsim tau ntau pua lossis qee zaum ntau pua tus duab.
Tej zaum yuav kom koj hnav lub tsho tshaj sab hauv tsev kho mob lossis khaub ncaws yam tsis muaj hlua khau hlau lossis txeeb khoom noj (xws li cov hws lossis lub tsho). Qee hom hlau tuaj yeem ua rau cov duab zim zuag.
Koj yuav tau pw saum lub rooj nqaim. Lub rooj zawv zawg hauv qhov loj me zoo li lub cav ntsuas kom tsim tau.
Qee qhov kev xeem yuav tsum muaj xim xeb tshwj xeeb (sib piv). Feem ntau, cov xim zas yog muab thaum lub sijhawm kuaj los ntawm txoj hlab ntshav (IV) hauv koj txhais tes lossis caj npab. 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 ntev li 30 mus rau 60 feeb, tab sis nws yuav siv sijhawm ntau 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 ntawm thaj chaw ze (muaj claustrophobia). Koj yuav tau muab tshuaj kom pab koj tsaug zog thiab tsis ntxhov siab. Koj tus kws kho mob kuj tseem yuav hais kom qhib MRI, hauv lub tshuab kom tsis zoo li koj lub cev.
Ua ntej sim, qhia rau koj tus kws kho mob yog tias koj muaj:
- Khoom cua plawv dhia ua ke
- Hlwb aneurysm txiav
- 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 khov kho, cov khoom hlau tsis pub nkag mus rau hauv chav tsev nrog MRI scanner. Zam kev nqa khoom xws li:
- Cov hnab tshos, cov npiv, thiab cov tsom iav
- Tshawb nrhiav, ntawv qiv nyiaj, ntawv nyiaj kub, thiab cov khoom siv hnov lus
- Cov plaub hau, cov zipp hlau, cov pins, thiab cov khoom sib xws
- Cov kev cog hniav uas tshem tau
Kev kuaj MRI ua rau tsis muaj mob. Koj tuaj yeem yuav muab tshuaj rau koj noj kom koj lub siab yog tias koj tseem muaj teeb meem dag lossis tseem muaj kev ntxhov siab. Tsiv ntau dhau tuaj yeem ua rau pom MRI cov duab thiab ua rau muaj qhov yuam kev.
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 kom pab txo 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 koj dhau sijhawm.
Tsis muaj lub sijhawm rov zoo li, tsuas yog koj tau muab tshuaj los pab koj so kom txaus. Tom qab kuaj MRI, koj tuaj yeem rov qab mus rau koj li qub kev noj haus, ua si, thiab tshuaj.
MRI lub plab muab cov ncauj lus kom ntxaws ntawm lub plab thaj chaw los ntawm ntau txoj kev pom. Nws feem ntau yog siv los qhia meej qhov kev tshawb pom los ntawm kev ntsuas dhau los ntawm ultrasound lossis CT scan kuaj.
Kev xeem no yuav raug siv los saib:
- Cov ntshav ntws hauv plab
- Cov hlab ntshav hauv plab
- Qhov ua rau mob plab lossis o tuaj
- Qhov ua rau kev kuaj ntshav tsis txaus, xws li teeb meem lub siab lossis raum
- Cov qog ua ntshav hauv plab
- Cov cev nqaij daim tawv nyob hauv daim siab, ob lub raum, adrenals, tus txiav, los yog tus po
MRI tuaj yeem paub qhov txawv qog ntawm cov nqaij zoo li qub. Qhov no tuaj yeem pab tus kws kho mob paub ntau dua ntawm cov qog xws li qhov loj me, mob hnyav thiab kis tau. Qhov no hu ua staging.
Qee qhov nws tuaj yeem muab cov lus qhia zoo dua qub txog cov neeg nyob hauv plab dua CT.
Qhov tshwm sim txawv txav tuaj yeem yog vim:
- Lub plab anortic aneurysm
- Qeb
- Mob qog lossis mob qog uas cuam tshuam rau cov qog adrenal, nplooj siab, leeg, plab, txiav, ob lub raum, ureters, hnyuv
- Coob o loj los yog mob siab
- Gallbladder lossis kua tsib cov teeb meem
- Hemangiomas
- Hydronephrosis (lub raum o tuaj ntawm qab zis)
- Mob raum
- Raum puas tsuaj lossis kab mob
- Raum pob zeb
- Tshab pom ntshav qab zib
- Obstructed vena cava
- Portal txoj hlab ntshav tav (nplooj siab)
- Thaiv lossis nqaim ntawm cov hlab ntshav uas xa ob lub raum
- Hlab ntsha leeg ntshav hlab ntsha
- Kev tso tseg lub raum lossis lub siab
- Cov mob ua paug rau daim siab
- Kev xa tawm ntawm cov qog nqaij hlav uas pib sab nraud lub plab
MRI tsis siv duab hluav taws xob ionizing. Tsis muaj kev phiv los ntawm cov teb sib nqus thiab xov tooj cua vuag tau tshaj tawm.
Qhov feem ntau ntawm cov sib piv (zas xim) siv yog gadolinium. Nws muaj kev nyab xeeb heev. Kev fab tshuaj tsis haum tab sis tuaj yeem tshwm sim. Yog tias koj muaj keeb kwm muaj kev txhaum fab hnyav rau lwm cov tshuaj koj yuav tsum qhia koj tus kws kho mob. Ib qho ntxiv, gadolinium tuaj yeem tsim kev puas tsuaj rau cov neeg muaj teeb meem lub raum uas xav tau lim ntshav. Qhia koj tus kws kho mob ua ntej kuaj yog tias koj muaj teeb meem raum.
Cov teb muaj zog loj heev uas tsim thaum lub MRI tuaj yeem ua rau lub plawv dhia ceev thiab lwm yam kev cog hniav kom tsis txhob ua haujlwm ib yam nkaus. Cov hlau nplaum tseem tuaj yeem ua rau ib daig hlau nyob hauv koj lub cev txav lossis hloov.
