Magnetoencephalography

Magnetoencephalography (mag-NEE-toe-en-sef-uh-low-graf-ee) ni uburyo bupima imikorere y'ubwonko. Urugero, ishobora gusuzuma ibice by'ubushyuhe bwa magneti bivuka mu mimerere y'amashanyarazi mu bwonko kugira ngo ibone ibice by'ubwonko bitera indwara z'ubwonko. Irashobora kandi gufasha mu kumenya aho ibintu by'ingenzi biri, nko kuvuga cyangwa gukora. Magnetoencephalography ikunze kwitwa MEG.

Iyo aribwo kubaga bikenewe, byiza cyane ni uko abagize itsinda ry’ubuvuzi bwawe bose bumva byose bashoboye ku bwonko bwawe. MEG ni uburyo budakomeretsa bwo gusobanukirwa ibice by’ubwonko bitera indwara zifata umutwe n’ibice bigira ingaruka ku mikorere y’ubwonko bwawe. MEG kandi ifasha itsinda ry’abaganga bawe kumenya ibice by’ubwonko bagomba kwirinda. Amakuru MEG itanga atuma gupanga igikorwa cyo kubaga biroroshye. Mu gihe kizaza, MEG ishobora gufasha mu kuvura indwara yo kunanirwa kw’ubwonko, imvune y’ubwonko iterwa n’impanuka, indwara ya Parkinson, indwara yo kwibagirwa, ububabare buhoraho, indwara y’ubwonko iterwa n’indwara y’umwijima n’izindi ndwara.

MEG ntikoresha amabuye y'imanywa. Ahubwo, iyi isuzuma ikoresha ibikoresho bipima neza uburyo bwa magnetique buva mu bwonko bwawe. Nta kintu na kimwe kizwi cyangiza ubuzima mu gupima ibi. Ariko, kugira umuringa mubiri bwawe cyangwa mu myenda yawe bishobora kubuza gupima neza kandi bishobora kwangiza ibikoresho bya MEG. Itsinda ry'abaganga bawe rigenzura ko nta muringa uri mubiri bwawe mbere y'isuzuma.

Ushobora kuzagabanya ibyo kurya n'amazi mbere y'ikizamini. Ushobora kandi kuzasabwa kureka imiti ukoresha buri munsi mbere y'ikizamini. Kurikiza amabwiriza uzahabwa n'abaganga bawe. Ugomba kwambara imyenda iruhura idafite amabuto ya métal, imisumari cyangwa imigozi. Ushobora kuzasabwa guhindura imyenda mbere y'ikizamini. Ntukambe imyambaro, ibikoresho bya métal, n'ibirungo byo kwisiga ndetse n'ibicuruzwa by'imisatsi kuko bishobora kuba birimo ibintu bya métal. Niba ibikoresho biri hafi y'umutwe bigutera ubwoba, baze ubaze abaganga bawe kubijyanye no gufata imiti ituma uryamye mbere y'ikizamini. Abana bato n'abana bashobora guhabwa imiti ituma baryama cyangwa anesthésie kugira ngo babafashe guhora bahagaze neza mu gihe cya MEG. Umuhanga mu buvuzi ashobora gusobanura ibyo umwana wawe akeneye n'ibyo ashobora guhitamo.

Ibikoresho bikoresha mu bipimo bya MEG bihambira ku mutwe nk'ingofero y'imodoka. Itsinda ry'abaganga bawe rigenzura uko umutwe wawe uhuye n'imashini mbere yo gukora ikizamini. Umwe mu itsinda ry'abaganga bawe ashobora kuguha ikintu cyo gushyira ku mutwe kugira ngo imashini ibe ishyizwe neza. Uricara cyangwa urasega neza mu gihe itsinda ry'abaganga bawe rigenzura uko bihuye. Ikizamini cya MEG kibera mu cyumba cyubatse mu buryo bwo kuburizamo ibikorwa bya magnetique bishobora gutuma ikizamini kidapima neza. Uba uri wenyine muri icyo cyumba mu gihe cy'ikizamini. Ushobora kuvugana n'abaganga mu gihe cy'ikizamini no nyuma yacyo. Ubusanzwe, ibizamini bya MEG ntibibabaza. Umuganga wawe ashobora gukora ikizamini cya electroencephalogram (EEG) icyarimwe na MEG. Niba ari uko, itsinda ry'abaganga bawe rizashyira izindi sensors ku mutwe wawe hakoreshejwe ingofero cyangwa kaseti. Niba ugiye gukorerwa iskaneri ya MRI kimwe na MEG, itsinda ry'abaganga bawe rishobora gukora MEG mbere kugira ngo bagabanye amahirwe yuko amabuye y'amaganete akomeye akoreshwa muri MRI ashobora kugira ingaruka ku ikizamini rya MEG.
