Reka twige ku bijyanye na MEG scan (Magnetoencephalography) isuzuma imikorere y'ubwonko.

Ese wowe cyangwa umuntu uzi ufite indwara nk'igicuri? Cyangwa wigeze wifuza kumenya neza aho ibice by'ingenzi by'ubwonko bigenzura imvugo n'ingendo biri mbere yo kubagwa ubwonko? Uyu munsi turimo kuvuga ku isuzuma rigezweho cyane, ritababaza, kandi ritekanye abaganga bakoresha mu bihe nk'ibi. Ryitwa MEG scan.

Mu magambo make, uyu MEG ni iki?

MEG, cyangwa Magnetoencephalography, ni ikizamini gipima imbaraga z'ubukuru zidasanzwe zikorwa n'ibimenyetso by'amashanyarazi bitangwa n'uturemangingo tw'ubwonko bwacu. Mu by'ukuri, ubu ni uburyo bwo gushushanya imikorere y'ubwonko bwacu.

Igishimishije ni uko nta bubabare na buke kandi ntibwanduza. Ibi bivuze ko nta nshinge zikoreshwa, nta gukomeretsa kwakozwe, kandi nta mirasire iyo ari yo yose iterwa n'imirasire, nka X-rays. MEG ni bwo buryo bugezweho ku isi bwo kwandika no gusuzuma imikorere y'ubwonko.

Ni mu bihe ibihe ikizamini cya MEG gikorerwa?

Abaganga b'indwara z'imitsi n'abaganga b'imitsi bakoresha iki kizamini cya MEG kubera impamvu ebyiri z'ingenzi.

Byongeye kandi, MEG ni igikoresho cy'ingenzi mu bushakashatsi bwa siyansi kugira ngo umuntu asobanukirwe neza imikorere y'ubwonko bw'umuntu.

Iyi mashini ikora ite?

Biroroshye cyane. Uturemangingo tw’ubwonko bwacu turakorana binyuze mu gukora voltage ntoya cyane z’amashanyarazi. Iyo iyi miyaga y’amashanyarazi itemba, imbaraga rukuruzi zibaho zizengurutse.

Imashini ya MEG ikoresha sensor zirenga 300 zifite ubushobozi bwo kumva ibintu cyane , zishyirwa ku gikoresho gisa n'ingofero wambara ku mutwe wawe, kugira ngo zimenye, zifate amajwi, kandi zisesengure izi powers za rukuruzi. Izi sensors zifite ubushobozi bwo kumva ibintu ku buryo zishobora gufata ndetse n'ipowers ntoya cyane za rukuruzi ziva mu bwonko bwacu. Izi sensors zitwa SQUIDs (superconducting quantum interference devices).

Izi sensor na porogaramu zidasanzwe za mudasobwa zikorana kugira ngo zifate imikorere y'ubwonko bwawe muri milisegonda ku milisegonda, waba wicaye cyangwa ukora ikintu runaka (urugero, ureba amashusho cyangwa usoma amagambo). Amaherezo, aya makuru ahuzwa n'ishusho y'ubwonko bwawe, igaragara kuri ecran ya mudasobwa nk'"ikarita" igaragaza ibice by'ubwonko bwawe bikora.

Ni gute wakwitegura ikizamini cya MEG?

Muganga wawe azaguha amabwiriza adasanzwe ukeneye mbere y'iki kizamini.

• Muganga azakubaza niba ukeneye kwirinda kurya cyangwa kunywa igihe runaka mbere yo kwipimisha.
• Bazanakugira inama niba hari icyo ugomba guhindura ku miti ufata.
• Ntukishyiremo amavuta yo kwisiga ku munsi w'ikizamini, kandi ntugakoreshe gel cyangwa spray ku musatsi wawe. Ibi bintu bishobora kubangamira ibisubizo by'ikizamini.
• Ntushobora kuzana ibintu by'icyuma mu cyumba cyo gupimiramo. Ibi bivuze ko ugomba gukuramo imitako, indorerwamo, udupira two mu mutwe, cyangwa amasutiye yo munsi y'icyuma. Nibiba ngombwa, ibitaro bizaguha ikanzu yihariye yo kwambara.

Icy'ingenzi: Menya neza ibice by'icyuma biri mu mubiri wawe

Niba ufite ibikoresho by’ubuvuzi byashyizwe mu mubiri wawe burundu cyangwa hanze yawo, ugomba kubibwira muganga wawe mbere yo kubipima. Hari ibikoresho birimo icyuma kandi bishobora kwangiza imbaraga za rukuruzi, bityo ushobora kutabishobora.

Ni iki kibaho mu gihe cy'ikizamini?

Uburyo ikizamini cya MEG gikorwa bushobora gutandukana gato bitewe n'impamvu yacyo, ariko akenshi bigenda gutya.

1. Kwitegura: Uzakuramo ibintu byose by'icyuma ku mubiri wawe maze wambare ikanzu yo kwa muganga.

2. Ku bana bato: Ku bana bato, bishobora kuba ngombwa kubaha imiti igabanya ububabare cyangwa igabanya ikinya, kuko bishobora kubagora kuguma bahagaze mu gihe cyo gupimwa.

3. Aho umutwe wawe uherereye: Pima aho umutwe wawe uherereye ugereranyije n'ingofero, hanyuma ushyireho utuzingo duto dutatu cyangwa tune duto dukoresheje kaseti y'agateganyo ahantu hatatu cyangwa ane ku mutwe wawe.

4. Gukuraho ibimenyetso bya rukuruzi: Hanyuma, igikoresho kizengurutse cyitwa "degausser" kizunguruka umubiri wawe kugira ngo gikureho ibimenyetso bya rukuruzi bidakenewe bishobora kuba byarundanyije mu mubiri wawe.

5. Kwicara mu ikizamini: Hanyuma uzategekwa kwicara mu ntebe yihariye ihujwe n'imashini ya MEG, cyangwa uzategekwa kuryama ku buriri.

6. Kwambara ingofero:Noneho, ingofero ifite sensor za MEG irashyizwe ku mutwe wawe. Ibi bigabanya ibyago byo kwandura claustrophobia. Kugira ngo ubone umusaruro mwiza, shyira umutwe wawe hafi y'ingofero uko bishoboka kose.

7. Mu gihe cy'ikizamini: Hari igihe uzasabwa kwicara ntuje, ndetse ushobora no gusinzira. Mu gupima ubwonko, uzasabwa gusoma amagambo kuri ecran, gusubiza ibibazo, cyangwa gukora utundi duto, nko gukanda buto. Hari igihe urutoki rwawe rushobora guhabwa akantu gato k'amashanyarazi kugira ngo rupime uko ubwonko bwawe bwitwara. Ibi bishobora kumvikana nk'aho ari ugutera akanya gato, ariko ntibibabaza.

8. Itumanaho: Icyumba cyo gupimiramo gifite intercom na sisitemu ya videwo, bityo ushobora kuvugana n'umuhanga mu gupimisha igihe icyo ari cyo cyose.

Iki kizamini cyose kimara isaha imwe cyangwa ebyiri.

Bigenda bite nyuma y'ikizamini?

Niba wowe cyangwa umwana wawe mwahawe ikinini cyo kuruhuka, abaganga bazagukurikirana mu gihe kingana n'igice cy'isaha kugeza ku masaha abiri. Uzakenera umuntu uzagufasha gutaha.

Niba utari ufite ikiruhuko, nta kibazo kirimo. Ushobora gukomeza imirimo yawe isanzwe ikizamini kirangiye.

Ni irihe tandukaniro riri hagati ya MEG, MRI na EEG?

Nubwo ibi bizamini uko ari bitatu bikorerwa ku bwonko, amakuru bapima kandi bakaduha aratandukanye.

Hari igihe abaganga bahuza amakuru aturuka ku bipimo bya MEG na MRI kugira ngo bakore ikarita y'imikorere y'ubwonko. Ibi byitwa MSI (Magnetic Source Imaging).
