Xav txog tias koj lossis ib tus neeg koj paub xav tau kev phais hlwb. Thawj qhov peb xav yog, "Auj, cov kws kho mob, koj paub li cas ua haujlwm yam tsis ua rau cov cheeb tsam tseem ceeb rau kev hais lus, kev txav mus los, thiab kev nco qab puas tsuaj?" Qhov ntawd yog ib lo lus nug loj. Hnub no peb tab tom tham txog kev luam theej tshwj xeeb uas pab nrog qhov ntawd, ib qho uas qhia daim ntawv qhia 'nyob' ntawm sab hauv ntawm lub hlwb. Qhov no hu ua fMRI, lossis Functional MRI scan.
Hauv lwm lo lus, fMRI yog dab tsi?
Tej zaum koj twb tau hnov txog kev thaij duab MRI lawm. Nws thaij tau cov duab peb-seem (3D) ntawm cov kab mob hauv peb lub cev kom pom tseeb heev. Nws tsis siv X-rays lossis hluav taws xob zoo li CT scans. Yog li ntawd, tsis muaj dab tsi yuav tsum ntshai.
Tam sim no, fMRI yog ib qho kev luam theej tshwj xeeb uas siv tib lub tshuab MRI. Tab sis qhov tshwj xeeb txog qhov no yog tias, ntxiv rau kev thaij duab ntawm lub hlwb, nws kuj qhia tau tias qhov twg ntawm lub hlwb ua haujlwm thaum lub sijhawm ntawd.
Nws ua haujlwm zoo li no: Thaum ib feem ntawm peb lub hlwb ua haujlwm, zoo li thaum peb tham, xav, lossis txav peb txhais tes, cov hlwb hlwb hauv qhov ntawd xav tau oxygen ntau dua. Ntau oxygen txhais tau tias ntshav ntws ntau dua. Lub tshuab fMRI tuaj yeem ntes tau qhov ntshav ntws ntau dua. Tom qab ntawd cov cheeb tsam uas nquag ua haujlwm zoo li ci dua ntawm daim duab scan.
Yog hais kom meej meej, daim duab MRI ib txwm zoo li daim ntawv qhia ntawm lub nroog uas qhia txog txoj kev thiab cov tsev. Tab sis fMRI zoo li 'daim ntawv qhia kev tsheb khiav tiag tiag' uas qhia ua xim tias txoj kev twg hauv lub nroog ntawd muaj tsheb khiav ntau tshaj plaws thiab muaj neeg coob tshaj plaws thaum lub sijhawm ntawd.
Cov kev siv ntawm cov scan no yog dab tsi?
Kev kos duab qhia txog kev ua haujlwm ntawm lub hlwb li no yog qhov tseem ceeb heev, tshwj xeeb tshaj yog rau kev npaj phais hlwb. Yog tias koj xav tau kev phais, tus kws phais hlwb tuaj yeem saib daim ntawv qhia fMRI no thiab npaj kev phais yam tsis ua rau puas tsuaj rau cov cheeb tsam uas tswj koj cov haujlwm tseem ceeb, xws li kev hais lus thiab kev txav mus los. Qhov no tuaj yeem ua tau rau cov neeg laus thiab cov menyuam yaus.
Piv txwv li, xav txog tias koj muaj ib lub qog hauv koj lub hlwb. Lub qog nyob ze ntawm qhov ntawm koj lub hlwb uas tswj koj cov ntiv tes li cas. Thaum lub sijhawm luam theej duab, koj raug hais kom txav koj cov ntiv tes. Daim duab fMRI qhia qhov chaw tseeb uas koj ua qhov kev nqis tes ua ntawd, uas ci ntsa iab. Tom qab ntawd tus kws phais paub tias yuav tsum tshem tawm lub qog kom zoo yam tsis txhob kov qhov chaw ntawd.
Cov xwm txheej tseem ceeb uas xav tau hom kev npaj no yog:
- Kab mob qaug dab peg: Yog tias muaj kab mob qaug dab peg uas tsis tau tswj los ntawm tshuaj, yog tias xav tau kev phais, yuav tsum tau saib xyuas kev ua haujlwm ntawm lub hlwb ua ntej phais.
- Cov qog hauv hlwb: Ua ntej phais kom tshem tawm cov qog mob cancer lossis cov qog tsis muaj teeb meem.
- Kev kho mob hluav taws xob:Thaum kho lub hlwb nrog kev siv hluav taws xob, txo qhov kev puas tsuaj rau cov khoom noj qab haus huv.
- Tom qab kev kho mob: Saib seb puas muaj kev hloov pauv hauv kev ua haujlwm ntawm lub hlwb tom qab qee yam kev kho mob.
Kuv yuav tsum npaj li cas ua ntej kev luam theej duab?
Kev npaj rau kev luam theej duab fMRI yog qhov tseem ceeb heev vim tias lub tshuab siv lub hlau nplaum muaj zog heev, yog li koj yuav tsum ceev faj heev txog koj txoj kev nyab xeeb.
Koj tus kws kho mob yuav piav qhia qhov no rau koj, tab sis feem ntau koj yuav tsum tau ua tib zoo mloog txog cov no.
- Tsis txhob haus dab tsi uas muaj caffeine (kas fes, tshuaj yej, qee yam dej qab zib) rau hnub uas yuav luam theej duab, vim nws yuav cuam tshuam rau cov txiaj ntsig ntawm kev luam theej duab.
- Qhia rau koj tus kws kho mob txog cov tshuaj uas koj noj. Nws yuav qhia koj seb puas yuav tsum noj ua ntej kev luam theej duab.
- Tsis txhob hnav lossis nqa dab tsi uas yog hlau . Tsis yog tsuas yog hlau uas muaj hlau nplaum xwb, tab sis kuj yog hlau uas tsis muaj hlau nplaum uas tuaj yeem cuam tshuam rau qhov meej ntawm daim duab luam theej.

Muaj dab tsi tshwm sim thaum lub sijhawm luam theej duab?
Ua qhov scan yog ib qho txheej txheem yooj yim heev.
Koj yuav raug yuam kom pw saum txaj, thiab tus neeg saib xyuas txaj yuav ua tib zoo coj koj mus rau hauv lub tshuab loj, voj voog. Ib lub cuab yeej tshwj xeeb (lub kauj taub hau) yuav raug muab tso rau ntawm koj lub taub hau, zoo li lub kaus mom hlau. Qhov no yuav pab ua kom cov duab ntawm koj lub hlwb meej dua. Koj tseem yuav tau txais lub mloog pob ntseg los pab koj thaiv lub suab nrov ntawm lub tshuab. Cov neeg ua haujlwm yuav muaj peev xwm tham nrog koj thiab muab cov lus qhia rau koj los ntawm cov mloog pob ntseg no.
Zoo li kuv tau hais ua ntej lawm, hauv kev thaij MRI ib txwm, koj tsuas yog raug hais kom nyob twj ywm xwb. Tab sis hauv kev thaij fMRI, koj raug hais kom ua tej haujlwm me me thaum lub sijhawm thaij duab.
Piv txwv li, koj yuav raug qhia tias:
- Co koj cov ntiv tes me ntsis.
- Hais ib kab lus luv luv.
- Saib ib daim duab ntawm qhov screen.
Thaum koj ua txoj haujlwm no, lub tshuab fMRI yuav sau cov cheeb tsam ntawm koj lub hlwb uas ua haujlwm. Koj tuaj yeem ua txoj haujlwm no tau ob txoj kev.
1. Lub kaw lus thaiv: Hauv qhov no, koj raug hais kom ua ib yam dab tsi rau ob peb feeb, tom qab ntawd tos ob peb feeb thiab tom qab ntawd ua dua.
2. Lub kaw lus tshwm sim: Qhov no tso cai rau koj ua ntau yam haujlwm sib txawv ib zaug.
Qee zaum lawv hais kom koj tsis txhob ua dab tsi li, tsuas yog zaum ntawd nrog koj ob lub qhov muag kaw lossis qhib xwb. Qhov no hu ua kev ntsuas "so state". Nws ntsuas kev ua haujlwm ntawm lub hlwb thaum koj so.
Qee zaum, cov tshuaj sib piv hu ua gadolinium yuav raug txhaj rau hauv cov leeg ntshav hauv koj txhais caj npab kom ua rau daim duab luam theej meej dua.
Feem ntau, tag nrho cov kev kuaj fMRI yuav siv sijhawm li ib teev .
Cov txiaj ntsig thiab qhov tsis zoo ntawm kev luam theej duab yog dab tsi?
Ib yam li lwm yam kev kuaj mob, fMRI muaj nws cov txiaj ntsig thiab qee qhov kev xav txog.
| Cov txiaj ntsig | Qhov Tsis Zoo / Kev Pheej Hmoo |
|---|---|
| Zoo heev rau kev npaj phais: Nws pab cov kws phais ua phais yam tsis ua rau cov feem tseem ceeb ntawm lub hlwb puas tsuaj. | Qis qeeb: Kev ua haujlwm ntawm lub hlwb hloov pauv hauv milliseconds. Tab sis fMRI siv sijhawm li ib vib nas this los thaij duab, yog li nws tsis tuaj yeem ntes tau kev hloov pauv sai heev. |
| Muaj Kev Nyab Xeeb: Tsis muaj hluav taws xob. Tsis yog kev kuaj mob uas cuam tshuam. | Cov kev pheej hmoo tsawg heev: Qhov kev pheej hmoo tseem ceeb yog cuam tshuam nrog cov hlau. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus qhia kev nyab xeeb kom meej. Cov kev phiv los ntawm cov khoom siv sib piv tsis tshua muaj. |
| Zoo dua li lwm yam kev xeem: Qhov no yog qhov tseeb dua thiab muaj tsawg dua cov kev phiv dua li qee qhov kev xeem cim lub hlwb. | Tsis yog txhua qhov chaw:Cov tshuab fMRI tsis muaj nyob rau hauv txhua lub tsev kho mob. Tej zaum koj yuav tau mus rau ib lub tsev kho mob loj dua rau qhov kev kuaj no. |
Qhov txawv ntawm fMRI thiab EEG yog dab tsi?
Ib qho EEG (Electroencephalogram) kuj yog ib qho kev xeem uas ntsuas kev ua haujlwm ntawm lub hlwb. Tab sis muaj qhov sib txawv loj ntawm ob qho no.
- fMRI qhia txog kev ua haujlwm ntawm lub hlwb ua ib daim duab . Peb tuaj yeem pom tseeb tias thaj chaw twg ntawm lub hlwb ua haujlwm.
- EEG qhia txog kev ua haujlwm ntawm lub hlwb ua cov nthwv dej kos rau ntawm daim ntawv lossis lub vijtsam.
Hais yooj yim xwb, thaum fMRI teb cov lus nug "qhov twg?", EEG rhiab heev rau cov lus nug "thaum twg?", uas yog, rau kev hloov pauv sai ntawm kev ua ub no.
Cov Lus Qhia Txog Kev Coj Mus Tsev
- fMRI yog ib qho kev ntsuas siab dua ntawm kev ntsuas MRI ib txwm muaj. Ntxiv rau kev thaij duab ntawm lub hlwb, nws kuj qhia tau tias qhov twg ntawm lub hlwb ua haujlwm thaum lub sijhawm ntawd.
- Qhov siv tseem ceeb ntawm qhov no yog ua ntej phais lub hlwb, los npaj phais kom tsis txhob ua puas rau cov cheeb tsam uas tswj cov haujlwm tseem ceeb xws li kev hais lus thiab kev txav mus los.
- Kev nyab xeeb yog qhov tseem ceeb tshaj plaws thaum mus rau kev kuaj fMRI. Nco ntsoov qhia rau koj tus kws kho mob thiab cov neeg ua haujlwm txog tej khoom hlau sab hauv lossis sab nraud koj lub cev.
- Qhov no yog ib txoj kev nyab xeeb thiab muaj txiaj ntsig zoo heev. Yog tias koj muaj lus nug txog qhov no, tsis txhob yig nug koj tus kws kho mob.
