Imajin se yu ɔ pɔsin we yu sabi nid fɔ gɛt ɔpreshɔn na in bren. Di fɔs tin we wi kin tink na, "O, dɔktɔ dɛm, aw una no fɔ ɔpreshɔn we nɔ go pwɛl di say dɛm we impɔtant fɔ tɔk, muvmɛnt, ɛn mɛmori?" Dat na big kwɛstyɔn. Tide wi de tok bɔt wan spɛshal skan we de ɛp wit dat, wan we de sho wan ‘layv’ map fɔ di insay pat na di bren. Dɛn kɔl dis fMRI, ɔ Functional MRI scan.
Fɔ tɔk am simpul wan, wetin na fMRI?
Sɔntɛm yu dɔn yɛri bɔt MRI skan. I de tek rili klia tri-dimɛnshɔnal (3D) pikchɔ dɛn fɔ di ɔgan dɛn we de insay wi bɔdi. I nɔ de yuz X-ray ɔ raytin lɛk CT skan. So natin nɔ de fɔ fred.
Naw, fMRI na spɛshal skan we de yuz di sem MRI mashin. Bɔt wetin spɛshal bɔt dis wan na dat, apat frɔm we i de tek pikchɔ fɔ di bren, i de sho bak us pat dɛn na di bren we de wok da tɛm de.
I de wok lɛk dis: We wan pat pan wi bren de wok, lɛk we wi de tɔk, tink, ɔ muv wi an, di bren sɛl dɛn na da pat de nid mɔ ɔksijɛn. Mɔ ɔksijɛn min se blɔd de flɔ mɔ. Di fMRI mashin kin no se blɔd de flɔ mɔ ɛn mɔ. Dɔn di say dɛn we de wok de sho brayt mɔ pan di skan.
Fɔ tɔk di kɔrɛkt tin, we pɔsin de du MRI ɔltɛm, i tan lɛk map fɔ wan siti we de sho di strit dɛn ɛn di bildin dɛn. Bɔt fMRI tan lɛk ‘layv trafik map’ we de sho wit kɔlɔ us strit dɛn na da siti de gɛt mɔ trafik ɛn we pipul dɛn kin ful-ɔp pas ɔl da tɛm de.
Wetin na di yus dɛm fɔ dis skan?
Fɔ map di bren aktiviti dis we rili impɔtant, mɔ fɔ plan fɔ ɔpreshɔn di bren. If yu nid fɔ du ɔpreshɔn, di nyurosɔjɔn kin luk dis fMRI map ɛn plan di ɔpreshɔn ɛn nɔ pwɛl di say dɛn we de kɔntrol yu impɔtant wok dɛn lɛk fɔ tɔk ɛn muv. Dɛn kin du dis pan big pipul dɛn ɛn bak pan pikin dɛn.
Fɔ ɛgzampul, imajin se yu gɛt tumbu na yu bren. Di tumbu de nia di pat na yu bren we de kɔntrol aw yu de muv yu finga dɛn. We dɛn de du di skan, dɛn kin aks yu fɔ muv yu finga dɛn. Di fMRI imej de sho di ekzak eria usay yu de du da akshɔn de, we de layt. Dɔn di dɔktɔ we de du di ɔpreshɔn no fɔ tek tɛm pul di tumbu we i nɔ tɔch da say de.
Di men tin dɛn we dɛn nid fɔ du dis kayn plan na:
- Epilepsy: If yu gɛt epilepsy we mɛrɛsin nɔ de kɔntrol, if dɛn nid fɔ du ɔpreshɔn, dɛn fɔ wach aw di bren de wok bifo dɛn du di ɔpreshɔn.
- Bren tumor: Bifo dɛn du ɔpreshɔn fɔ pul di tumor dɛn we gɛt kansa ɔ we nɔ gɛt wan prɔblɛm.
- Redyushɔn tɛrapi: .We yu de trit di bren wit raytin, nɔ pwɛl di pat dɛn we gɛt wɛlbɔdi.
- Afta tritmɛnt: Si if chenj de na di bren wok afta sɔm tritmɛnt.
Aw a fɔ pripia bifo di skan?
Fɔ pripia fɔ fMRI skan rili impɔtant bikɔs di mashin de yuz magnet we rili strɔng, so yu nid fɔ rili tek tɛm bɔt yu sef.
Yu dɔktɔ go ɛksplen dis to yu, bɔt bɔku tɛm yu fɔ pe atɛnshɔn to dɛn tin ya.
- Nɔ drink ɛnitin we gɛt kafin (kɔfi, ti, sɔm sɔft drink) di de we dɛn de skan, bikɔs i kin afɛkt di skan rizɔlt.
- Tɛl yu dɔktɔ bɔt ɛni mɛrɛsin we yu de tek. I go advays yu if yu fɔ tek dɛn bifo di skan.
- Nɔ wɛr ɔ kɛr ɛnitin we gɛt mɛtal . Nɔto jɔs mɛtal we gɛt magnɛtik, bɔt mɛtal we nɔ gɛt magnɛtik kin afɛkt di klia we aw di skan de.

Dɔn bak, if yu gɛt klaustrophobia (frayd fɔ smɔl, lɔk ples), tɛl yu dɔktɔ bifo tɛm. If nid de, di dɔktɔ kin gi yu smɔl mɛrɛsin fɔ mek yu at kol.
Wetin kin apin we dɛn de du di skan?
Fɔ du di skan na tin we rili simpul.
Dɛn go mek yu ledɔm na bed, ɛn di pɔsin we de wok na di bed go tek tɛm gayd yu fɔ go insay wan big mashin we gɛt sɛkɔla. Dɛn go put spɛshal tin (ed kɔyl) na yu ed, lɛk ɛlmɛt. Dis go ɛp fɔ mek di pikchɔ dɛn na yu bren klia. Dɛn go gi yu ɛdfɔn bak fɔ ɛp yu fɔ blok di nɔys we de kɔmɔt na di mashin. Di wan dɛn we de wok de go ebul fɔ tɔk to yu ɛn gi yu instrɔkshɔn tru dɛn ɛdfɔn ya.
As a don tok bifo, fo regular MRI, dem jos tel yu fo ste stil. Bɔt insay fMRI, dɛn kin aks yu fɔ du smɔl smɔl wok dɛn we dɛn de du di skan.
Fɔ ɛgzampul, dɛn go tɛl yu se:
- Wiggle yu finga dɛn smɔl.
- Se wan shɔt sɛntɛns.
- Luk wan pikchɔ we de na di skrin.
As yu de du dis wok, di fMRI mashin de rikodɔ di say dɛn na yu bren we de wok. Yu kin du dis wok tu we dɛn.
1. Blɔk sistɛm: Insay dis, dɛn kin tɛl yu fɔ du sɔntin fɔ sɔm sɛkɔn, dɔn wet fɔ sɔm sɛkɔn ɛn du am bak.
2. Ivent sistem: Dis de mek yu ebul fɔ du sɔm difrɛn wok dɛn wan tɛm.
Sɔntɛnde dɛn kin aks yu fɔ nɔ du natin, jɔs sidɔm de wit yu yay we yu lɔk ɔ opin. Dɛn kɔl dis "rɛst stet" skan. I de mɛzhɔ di bren aktiviti we yu de rɛst.
Sɔntɛnde, dɛn kin injɛkt wan kɔntrast ɛjɛn we dɛn kɔl gadolinium insay wan vein na yu an fɔ mek di skan klia.
Di wan ol fMRI skan kin tek lɛk wan awa so .
Wetin na di bɛnifit ɛn bad tin dɛn we di skan gɛt?
Lɛk ɛni mɛdikal tɛst, fMRI gɛt in bɛnifit ɛn sɔm tin dɛn we pɔsin fɔ tink bɔt.
| Bɛnifit dɛn | Di bad tin dɛn we kin apin / Risk dɛn |
|---|---|
| I fayn fɔ plan fɔ du ɔpreshɔn: I kin ɛp dɔktɔ dɛn fɔ du ɔpreshɔn we nɔ go pwɛl impɔtant pat dɛn na di bren. | Slow spid: di wok we di bren de du de chenj insay milisekɔnd. Bɔt fMRI kin tek lɛk wan sɛkɔn fɔ tek pikchɔ, so i nɔ kin ebul fɔ kech di chenj dɛn we kin apin kwik kwik wan. |
| Sef: Nɔ gɛt raytin. Nɔto wan invasive tɛst. | Di risk dɛn rili smɔl: Di men risk gɛt fɔ du wit di mɛtal. So, i impɔtant fɔ fala di tin dɛn we dɛn tɛl yu fɔ du fɔ mek yu nɔ gɛt prɔblɛm. Sayd ifekt frɔm kɔntrast matirial nɔ kin rili bɔku. |
| I bɛtɛ pas ɔda tɛst dɛn: Dis kin kɔrɛkt ɛn i nɔ kin gɛt bɛtɛ sayd ɛfɛkt pas sɔm ɔda tɛst dɛn we dɛn kin du fɔ mek yu bren map. | Nɔto ɔlsay:fMRI mashin nɔ de na ɔl di ɔspitul dɛn. Yu kin gɛt fɔ go na big ɔspitul fɔ dis tɛst. |
Wetin na di difrɛns bitwin fMRI ɛn EEG?
EEG (Electroencephalogram) na tɛst bak we de sho aw di bren de wok. Bɔt big difrɛns de bitwin dɛn tu.
- fMRI de sho di bren aktiviti as pikchɔ . Wi kin si di rayt say dɛn na di bren we de wok.
- EEG de sho di bren aktiviti lεk wev dεm we dεn drכ pan pepa כ skrin.
Fɔ tɔk am simpul wan, we fMRI de ansa di kwɛshɔn "we?", EEG de mɔ sɛnsitiv to di kwɛshɔn "we?", dat na to chenj dɛn we de apin kwik kwik wan na di aktiviti.
Mɛsej we dɛn kin kɛr go na os
- fMRI na wan advans vεshכn fכ wan rεgulεr MRI skan. Apat frɔm we i de tek pikchɔ fɔ di bren, i de sho bak us pat dɛn na di bren we de wok da tɛm de.
- Di men tin we dɛn kin yuz dis na bifo dɛn du ɔpreshɔn pan di bren, fɔ plan di ɔpreshɔn so dat i nɔ go pwɛl di say dɛn we de kɔntrol impɔtant wok dɛn lɛk fɔ tɔk ɛn muv.
- Sefty na nɔmba wan we yu de go fɔ fMRI skan. Mek shɔ se yu tɛl yu dɔktɔ ɛn di wan dɛn we de wok de bɔt ɛni mɛtal tin we de insay ɔ ausayd yu bɔdi.
- Dis na wan we we rili sef ɛn we yusful. If yu gɛt ɛni kwɛstyɔn bɔt dis, nɔ shek fɔ aks yu dɔktɔ.
