MRI

Ib qho ntsuas qhov sib piv ntawm cov hlau nplaum (MRI) yog ib qho kev ntsuam xyuas uas siv cov hlau nplaum muaj zog thiab xov tooj cua tshaj tawm los tsim cov duab hauv lub cev. Nws tsis siv duab hluav taws xob ionizing (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 soj ntsuam tuaj yeem tsim tau ntau phav phav cov duab.

MRI ntau hom xws li:

• MRI Thawv
• Mob ncauj tsev me nyuam MRI
• Hauv siab MRI
• Kev Tshawb Fawb MRI
• Lub plawv MRI
• LAB MRI
• Pelvic MRI
• MRA (MR Angiography)
• MRV (MR Venography)

Tej zaum yuav kom koj hnav lub tsho tshaj sab hauv tsev kho mob lossis khaub ncaws yam tsis muaj zippers lossis txeeb khoom noj (xws li cov hws lossis lub tsho loj). Qee hom hlau tuaj yeem ua rau cov duab zim zuag.

Koj yuav tau pw ntawm lub rooj nqaim, uas zawv zawv mus rau hauv lub qhov ntxaij uas loj dua me.

Qee qhov kev xeem yuav tsum muaj xim xeb tshwj xeeb (sib piv). Feem ntau, cov xim yuav muab los ntawm txoj leeg (IV) hauv koj txhais tes lossis caj npab ua ntej ntsuas. Zas yuav pab cov kws ntsuas hluav taws xob pom qee thaj chaw kom pom tseeb.

Cov cuab yeej me, hu ua coils, tuaj yeem tso nyob ib ncig ntawm lub taub hau, caj npab, lossis ceg, lossis ib puag ncig lwm qhov chaw uas yuav tau kawm. Cov no pab xa thiab txais cov xov tooj cua, thiab txhim kho cov duab zoo.

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 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 ntawm thaj chaw ze (muaj claustrophobia). Tej zaum koj yuav tau muab tshuaj kom pab koj tsaug zog thiab tsis ntxhov siab, lossis koj tus kws kho mob yuav hais kom qhib MRI, uas lub tshuab tsis zoo li 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
• 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:

• Cov khoom xws li cov hniav nyiaj hniav kub, watches, credit card, thiab khoom siv tau hnov ​​tau ua kom puas ntsoog.
• Cwjmem, hnab looj tes, thiab tsom iav yuav ya hla chav.
• 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. Yog tias koj muaj teeb meem dag tsis tau tseem ceeb lossis ntxhov siab, koj yuav tau muab tshuaj rau koj los so koj. 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 daim pam lossis tog hauv ncoo. Lub tshuab ua suab nrov nrov nrov thiab lub suab nrov thaum tig mus. 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 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 pib dua koj li kev noj haus, kev ua si, thiab tshuaj.

Muaj MRI pab tau feem ntau:

• Kev kuaj mob muaj tus mob
• Coj tus kws kho mob mus rau thaj chaw yog thaum lub sijhawm kuaj ntshav
• Txheeb xyuas cov noob thiab qog, nrog rau mob qog noj
• Kawm cov hlab ntshav

MRI cov duab thaij tom qab zas tshwj xeeb (qhov tsis sib xws) xa mus rau koj lub cev yuav muab cov ntaub ntawv ntxiv txog cov hlab ntshav.

Qhov sib txawv ntawm lub ntsej muag sib nqus (angiogram) (MRA) yog ib hom kev sib nqus ntawm cov hlau nplaum uas tsim cov duab-3-seem ntawm cov hlab ntsha.

Ib qho txiaj ntsig tshwm sim txhais tau tias thaj chaw ntawm lub cev tau kawm nws zoo li qub.

Cov txiaj ntsig yog nyob ntawm ib feem ntawm lub cev tau kuaj thiab qhov xwm ntawm teeb meem. Txawv cov ntaub ntawv sib txawv xa rov qab sib txawv MRI cov cim. Piv txwv li, cov ntaub so ntswg noj qab haus huv xa rov qab lub suab sib txawv dua li cov nqaij mos. Sab laj rau koj tus kws kho mob yog muaj lus nug thiab kev txhawj xeeb.

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. Qhov tshuaj yeeb tshuaj no xav hais tias nws yuav nyab xeeb rau cov neeg feem coob. Gadolinium khaws cia rau hauv lub hlwb thiab lwm yam kabmob (suav nrog cov tawv nqaij hauv cov neeg muaj mob raum) tom qab siv. Tsawg tsawg zaus, kev hloov khoom nruab nrog cev thiab daim tawv nqaij tau tshwm sim hauv cov neeg mob preexisting raum tsis ua haujlwm.Qhov koj tus kws kho mob ua ntej kuaj yog tias koj muaj teeb meem lub 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.
