MEG leh MRI hi eng nge an danglamna?

Heng pahnih hi thluak test ni mahse, a danglamna tlem a awm.

• Thluak MRI (magnetic resonance imaging) hian magnet lian tak leh computer hmangin structural information khawlkhawmin i thluak thlalak a siam thin. Chu chu thluak hi eng ang nge a nih tih leh a peng hrang hrangte inrem dan tihna a ni.
• MEG hian i thluaka nerve cell (neurons) atanga magnetic field lo chhuakte chu special sensor za tam tak leh computer hmangin record a ni.Heng field te hi thluak wave angin an lang thin.

Doctor-te chuan MRI leh MEG te chu an hmang dun a, Magnetic Source Imaging (MSI) tih chu an ti fo thin. MSI hian thluak hnathawh dan functional map a siam thei a ni.

MEG hi functional MRI (fMRI) nen pawh a danglam bawk. fMRI hian hna thenkhat i tih hian i thluak hmun thenkhata thisen kal dan inthlak danglamna a en thin. MEG leh fMRI te hian thluak hnathawh hi an en a, mahse MEG hian hnathawhna hmun bik a lantir thung. fMRI hian hmun tlangpui a tarlang. Tin, MEG hian hun kal zelah thluak hnathawh a inthlak dan (temporal characteristics) a lantir thiam zawk bawk.

MEG leh EEG hi eng nge an danglamna?

Heng diagnostic test pahnih inthlauhna hmasa ber chu:

• EEG (electroencephalography) hian i thluak electric hnathawh dan a record a.
• MEG hian i thluaka magnetic field (electric activity avanga lo awm) te chu a record thin.

A danglamna dang chu MEG hian EEG aiin thluak hnathawh record-naah a sensitive zawk a, a dik zawk bawk. I luruh leh cerebrospinal fluid (CSF) hian EEG-in a record electrical activity chu a tichhe thei a ni. Mahse, heng tissue te hian magnetic field te chu an tichhe lo. Hei hian MEG chu i thluak “image” tha zawk, a nih loh leh spatial resolution . Chu chu, thil tih dan pangngai lo awmna hmunte a finfiah thei tihna a ni.

A châng chuan doctor-te chuan thluak hnathawhna hmun aṭanga lo chhuak tih hriat belh nân MEG rualin EEG an ti ṭhin.

I tan thuchah pawimawh tak a ni.

I hmuh angin he test hi Magnetoencephalography (MEG) tia koh a ni a, test tangkai tak, hlauhawm lo leh him tak a ni a, doctor-te chuan i thluak hmun sensitive tak takte map-ah a pui a, seizure ang chi thil awmna hmun dik tak a hriat theih nan a pui bawk.

``(MEG)`` test i neih a, i ngaihtuahna leh rinhlelhna i neih chuan i doctor zawt ngei ang che. I zawhnate chhang tur leh thlawp turin an awm reng a ni. Engmah hlau suh!
