Xav txog koj tus phooj ywg tab tom phais kom tshem tawm ib lub qog hauv ib feem ntawm nws lub hlwb uas nyuaj heev. Cov kws kho mob ua tib zoo ua qhov phais. Tab sis lawv yuav paub tseeb li cas tias lub qog tau raug tshem tawm tag nrho lossis puas tseem muaj ib daim me me? Tom qab phais, yog tias koj ua qhov scan dua ob peb hnub tom qab, koj tuaj yeem paub tseeb. Yog tias tseem muaj ib daim me me, koj yuav tsum tau phais dua, puas yog? Cov thev naus laus zis tshwj xeeb no uas peb tab tom tham txog hnub no yog siv los daws cov teeb meem zoo li no.
Hais yooj yim xwb, iMRI yog dab tsi?
Lub npe tag nrho rau iMRI yog Intraoperative Magnetic Resonance Imaging . "Intraoperative" txhais tau tias "thaum lub sijhawm phais." Qhov no txhais tau tias nws yog MRI scan uas ua thaum lub sijhawm phais . Qhov no tso cai rau koj pab neeg phais pom cov kabmob, cov nqaij, thiab lwm yam hauv koj lub cev kom meej meej thaum lub sijhawm phais.
Xav txog ib tug kws kho mob uas tab tom tshem ib lub qog tawm ntawm lub hlwb. Nws tuaj yeem ua qhov MRI scan tam sim ntawd tom qab tshem lub qog tawm, ua ntej phais tiav, kom pom, "Kuv puas tau tshem tag nrho cov qog? Los yog tseem muaj tej daim me me seem?" Yog tias daim scan qhia tias tseem muaj ib daim me me seem, nws tuaj yeem tshem qhov ntawd tam sim ntawd.
Qhov zoo tshaj plaws ntawm qhov no yog tias kev paub tias muaj qee qhov ntawm cov qog nqaij hlav tshuav tom qab phais mob tuaj yeem txo qhov kev pheej hmoo ntawm kev yuav tsum tau phais zaum ob.
Qhov txawv ntawm MRI ib txwm thiab iMRI yog dab tsi?
Qhov txawv tseem ceeb thiab tsuas yog qhov txawv ntawm ob qho no yog lub sijhawm nws siv los ua nws .
- Ib daim MRI li niaj zaus: Qhov no yog ua los kuaj mob lossis npaj phais. Koj mus rau hauv lub tshuab MRI li niaj zaus thiab ua qhov kev luam theej no.
- Ib qho iMRI: Qhov no ua thaum lub sijhawm phais mob , sab hauv chav phais.
Hais yooj yim xwb, ib qho ua tiav ua ntej kev phais, thiab lwm qhov ua tiav thaum lub sijhawm phais nws tus kheej.
Vim li cas cov kws kho mob thiaj siv cov thev naus laus zis no thaum lub sijhawm phais?
Qee qhov kev phais mob, tshwj xeeb tshaj yog kev phais lub hlwb, yog qhov nyuaj heev. Txawm tias qhov sib txawv ntawm ib millimeter tuaj yeem muaj kev cuam tshuam loj heev. Tus kws kho mob xav tau daim duab meej dua, pom tseeb dua thaum lub sijhawm phais mob dua li qhov lawv pom nrog lawv tus kheej lub qhov muag lossis los ntawm lub tshuab microscope. Thaum ntawd qhov tseem ceeb ntawm iMRI thiaj li pom tseeb.
Nov yog qee qhov kev siv thev naus laus zis iMRI feem ntau:
| Hom kev phais mob | Kev pab los ntawm iMRI |
|---|---|
| Kev Tshem Tawm Mob Hlwb | Txhawm rau kom paub tseeb tias qhov mob qog nqaij hlav puas raug tshem tawm tag, lossis puas tuaj yeem tshem tawm ntau qhov chaw yam tsis ua rau cov nqaij noj qab haus huv puas tsuaj. Qhov no tseem ceeb heev rau cov qog nqaij hlav xws li glioma . |
| Mob qog ntawm lub qog pituitary | Thaum tshem tawm cov qog nqaij hlav nyob ib puag ncig lub qog pituitary, ib feem ntawm lub hlwb uas rhiab heev, los xyuas seb puas muaj kev puas tsuaj rau cov hlab ntsha tseem ceeb thiab cov hlab ntsha nyob ze. |
| Kev Txhawb Nqa Lub Hlwb tob (DBS) | Thaum muab cov electrodes ntxig rau hauv lub hlwb tob rau cov mob xws li tus kab mob Parkinson , kom ntseeg tau tias lawv tau muab tso rau qhov chaw raug. |
| Kev Phais Mob Qaug Dab Peg | Txhawm rau txheeb xyuas qhov tsis zoo ntawm lub hlwb uas ua rau muaj tus mob qaug dab peg thiab xyuas seb nws puas tau raug tshem tawm tag. |
| Kev phais lub taub hau | Hauv txhua qhov kev phais mob nyuaj uas cuam tshuam nrog lub hlwb, yuav tsum kuaj xyuas seb lub hlwb puas zoo (o, los ntshav) thaum kawg ntawm kev phais. |
Lub tshuab iMRI no ua haujlwm li cas?
Kev thaij duab MRI yog ib lub tshuab uas siv cov hlau nplaum thiab cov nthwv dej xov tooj cua los thaij duab sab hauv lub cev. Qhov ntawd yog qhov tshwm sim hauv iMRI. Koj yuav tsis hnov nws vim tias koj raug tshuaj loog thiab feem ntau tsis nco qab kiag li.
Nov yog nws ua haujlwm li cas, hais yooj yim:
Ntau tshaj ib nrab ntawm peb lub cev yog ua los ntawm dej. Dej yog ua los ntawm cov hydrogen thiab cov pa oxygen. Sab hauv cov hydrogen atom no yog ib qho me me hu ua proton . Cov protons no muaj hluav taws xob, thiab lawv kuj tig.
Lub tshuab MRI xa ib lub zog sib nqus loj heev hla koj lub cev. Qhov tshwm sim yog tias tag nrho cov protons no hauv koj lub cev sib dhos ua ke rau tib qho kev taw qhia, zoo li lub koob qhia kev taw qhia mus rau sab qaum teb.
Tom qab ntawd, lub tshuab MRI xa ib nthwv dej ntawm cov nthwv dej xov tooj cua los ntawm lub zog sib nqus no. Qhov no zoo li lub qhov rooj ntawm lub koob yees duab thaij duab. Cov nthwv dej xov tooj cua no cuam tshuam qhov sib phim ntawm cov protons ib ntus. Thaum cov nthwv dej xov tooj cua nres, cov protons rov qab mus rau lawv qhov sib phim qub. Qhov kev hloov pauv no raug khaws los ntawm lub tshuab scanner hauv lub tshuab. Cov ntaub ntawv raug xa mus rau lub khoos phis tawj, uas tsim cov duab peb-seem (3D) meej heev.
Kuv yuav npaj li cas rau iMRI?
Qhov tseeb, koj tsis tas yuav npaj rau iMRI vim nws tshwm sim thaum koj phais. Txhua yam koj yuav tsum ua yog npaj rau koj qhov kev phais kom zoo. Ua raws li koj tus kws kho mob cov lus qhia raws nraim li lawv yuav qhia koj.
Koj yuav raug tshuaj loog thaum lub sijhawm ua haujlwm, yog li koj yuav tsaug zog. Yuav muaj qee lub suab nrov thaum lub tshuab MRI ua haujlwm, tab sis koj yuav tsis hnov nws vim yog tshuaj loog. Qee zaum, muaj cov txheej txheem tsim. Hauv cov xwm txheej zoo li no, pab pawg kho mob yuav npaj koj rau cov txheej txheem thiab xyuas kom meej tias koj xis nyob thaum lub sijhawm luam theej duab.
Tej yam koj yuav tsum qhia rau koj tus kws kho mob ua ntej phais:
- Yog li ntawd, yog tias koj cev xeeb tub .
- Yog tias koj muaj ib yam dab tsi uas muaj hlau cog rau hauv koj lub cev. Piv txwv li, lub tshuab pacemaker, cov phaj hlau tso rau hauv lub cev, cov pob qij txha cuav, thiab lwm yam. Cov hlau nplaum muaj zog hauv MRI tuaj yeem ua rau cov no txav mus los lossis ua haujlwm tsis zoo. Qhov no txaus ntshai. Yog li ntawd, yog tias koj tau qhia txog qhov no ua ntej, pab pawg kho mob yuav ua cov kev ntsuas kev nyab xeeb tsim nyog.
- Ua ntej phais mob, koj yuav tsum tshem tawm txhua yam khoom hlau ntawm koj lub cev, xws li cov hniav nyiaj hniav kub, cov pob ntseg, cov koob txuas plaub hau, thiab cov xov hlau hauv koj lub ris tsho hauv qab .
Cov txiaj ntsig ntawm iMRI yog dab tsi?
Muaj ntau qhov zoo tseem ceeb rau kev siv cov thev naus laus zis iMRI.
- Cov duab meej heev: Thaj chaw ntawm lub cev uas raug phais tuaj yeem pom meej heev thiab ntxaws ntxaws.
- Cov ntaub ntawv tiag tiag: Cov duab no tuaj yeem saib tau thaum lub sijhawm phais, ua rau kev txiav txim siab tau yam tsis muaj kev ncua.
- Kev Soj Ntsuam Kev Hloov Pauv: Koj tuaj yeem pom tam sim ntawd seb thaj chaw ntawd tau hloov pauv li cas thaum lub sijhawm phais (piv txwv li tom qab tshem tawm ib qho qog).
- Tiv thaiv cov teeb meem: Cov duab meej no tuaj yeem txo cov teeb meem uas yuav tshwm sim tom qab phais mob.
- Tsis muaj hluav taws xob: Cov thev naus laus zis MRI tsis siv hluav taws xob zoo li X-rays lossis CT scans, yog li nws tsis ua rau lub cev puas tsuaj.
Tus kws kho mob tuaj yeem pom cov txiaj ntsig no hauv ob peb feeb ntawm kev luam theej duab, uas tso cai rau nws mus rau kauj ruam tom ntej ntawm kev phais yam tsis muaj kev ncua.
Cov Lus Qhia Txog Kev Coj Mus Tsev
- Ib qho iMRI yog ib daim duab MRI tshwj xeeb uas ua thaum lub sijhawm phais.
- Lub hom phiaj tseem ceeb ntawm qhov no yog muab sijhawm rau cov kws kho mob ua phais kom pom sab hauv lub cev kom meej meej thiab muaj sia nyob.
- Qhov no pab kom paub tseeb tam sim ntawd seb puas tau muab lub qog tshem tawm tag, tshwj xeeb tshaj yog hauv kev phais mob nyuaj xws li kev tshem tawm lub qog hauv hlwb.
- Qhov no txo qhov xav tau kev phais zaum ob ntau heev.
- Yog tias koj yuav phais nrog iMRI, nco ntsoov qhia rau koj tus kws kho mob ua ntej txog cov khoom siv hlau, xws li lub tshuab pacemakers, uas koj tau cog rau hauv koj lub cev.
