Reka twige ku ikizamini cya Magnetoencephalography (MEG), gipima imikorere y'ubwonko bwawe.

Ese wigeze wumva iki kizamini cyitwa `(Magnetoencephalography)` cyangwa `(MEG)`? Wenda wowe cyangwa undi muntu uzi yabwiwe na muganga kubikora. Ntutinye, ubu buryo mu by'ukuri ni uburyo bugezweho bwo gupima, kandi ntacyo bwangiza ku mubiri wacu. Uyu munsi, tuzaganira kuri iki kizamini cya `(MEG)` mu buryo bworoshye ushobora gusobanukirwa.

MEG ni iki? Biroroshye cyane!

Mu magambo make, `(MEG)` ni ikizamini gipima imbaraga rukuruzi zikorwa n'amashanyarazi mu bwonko bwawe. Tekereza, ni nk'ubutumwa buto bw'amashanyarazi burimo guhanahana mu bwonko bwacu. Iyi ngufuri ikora imbaraga rukuruzi. Iyo ngufu rukuruzi ni yo iyi mashini `(MEG)` ipima.

Ibi bituma abaganga babona imikorere y'ubwonko bwawe nk'ikarita. Ibi birafasha cyane cyane mu ndwara nka epilepsy , aho bashobora kumenya neza aho indwara zo mu bwonko zituruka .

Igikuru ni uko iki kizamini kidatera ingaruka mbi ku mubiri (`noninvasive`). Ibyo bivuze ko udakeneye gushyiramo inshinge cyangwa kubagwa. Ntuhura n'imirasire nka `(X-rays)`. Mu buryo buriho ubu, ubu `(MEG)` ni bwo buryo bugezweho bwo kwandika no gusesengura imikorere y'ubwonko.

Ni izihe nyungu zo gukoresha ibizamini bya MEG?

Abaganga b'indwara z'imitsi n'abaganga b'imitsi bakoresha iki kizamini (MEG) kubera impamvu ebyiri z'ingenzi:

1. Suzuma imikorere y'ubwonko bwawe. Ibi bishobora gufasha kumenya neza aho indwara y'igicuri iherereye ku muntu urwaye igicuri. Ibi ni ingenzi cyane mu gutegura kubagwa. Tekereza Samantha arwaye igicuri kandi akeneye kubagwa. Hanyuma abaganga bakora MEG kugira ngo barebe igice cy'ubwonko indwara y'igicuri ituruka, hanyuma bakibanda kuri icyo gice gusa hanyuma bagakora kubagwa.

2. Suzuma uburyo ubwonko bwawe bwakira ibintu bigutera kumva ibintu biturutse hanze.Ibi bituma haboneka ikarita nyayo y'ibice by'ubwonko bifitanye isano n'ingendo, ibyiyumvo, ururimi, kureba, nibindi. Ibi ni ingirakamaro cyane mu gutegura kubaga abantu bafite ibibyimba byo mu bwonko.

Byongeye kandi, MEG ni igice cy'ingenzi cyane mu bushakashatsi ku mitsi n'indwara zo mu mutwe, aho abahanga mu bya siyansi bakora ubushakashatsi kugira ngo basobanukirwe neza imikorere y'ubwonko bw'umuntu.

Ikizamini cya MEG gikora gite? Ni siyansi gato, ariko byoroshye!

Uturemangingo tw’imitsi mu bwonko bwacu tubwirana binyuze mu gukora voltage nto z’amashanyarazi. Iyo izi ngufu z’amashanyarazi zitemba, zirema imbaraga za rukuruzi. Izo ngufu za rukuruzi ziraboneka, zikandikwa, kandi zigasesengurwa n’ibikoresho by’ingufu bya rukuruzi by’ibanga biri mu mashini ya MEG.

Ariko, iyi ngufu ya rukuruzi ikorwa n'ubwonko bwawe ni nke cyane. Kubwibyo, hakenewe sisitemu zidasanzwe zo gupima kugira ngo hafatwe icyo kimenyetso. Izi sisitemu zigizwe n'udupira duto kandi dufite ubushobozi bwo hejuru. Izi zihujwe n'ibikoresho byitwa SQUIDs - superconducting quantum interference devices. Hari utu tumashini turenga 300 muri two mu gikoresho gisa n'ingofero wambara mu gihe cy'ikizamini.

Mu gihe uryamye, rimwe na rimwe wumva amajwi, cyangwa ukora ikintu nko kureba amashusho, ibikoresho by'ubuhanga biri muri iyi ngofero, hamwe na porogaramu za mudasobwa zihariye, bikorana kugira ngo bimenye kandi bifate imikorere y'uturemangingo tw'imitsi. MEG yandika ibimenyetso bisanzwe n'ibidasanzwe mu bwonko buri milimetero . Izi ngufu za rukuruzi zerekwa kuri ecran ya mudasobwa hamwe n'ishusho y'ubwonko bwawe. Ibi bigufasha "gushushanya" aho ibikorwa bimwe na bimwe by'ubwonko bitangirira n'igihe bibera.

Witegura ute ikizamini cya MEG?

Niba uri gupimwa na MEG, muganga wawe azakubwira niba ukeneye guhagarika kurya cyangwa kunywa mbere yo kwipimisha. Azakubwira kandi niba ukeneye guhindura imiti yawe cyangwa gahunda yawe ya buri munsi.

• Ntukambike amavuta yo kwisiga cyangwa gukoresha imisatsi ku munsi w'ikizamini. Bishobora kubangamira ikizamini.
• Nanone, ntushobora kuzana ibintu by'icyuma mu cyumba cy'isuzuma. Urugero, imitako, indorerwamo, udupira two mu mutwe, amasutiye yo munsi y'icyuma, n'imyenda irimo ibikoresho by'icyuma. Nibiba ngombwa, uzahabwa ikanzu yo kwa muganga yo kwambara.

Icy'ingenzi:Niba ufite ibikoresho byo kwa muganga byashyizwe mu mubiri wawe cyangwa hanze yawo, ugomba kubibwira muganga mbere yo kubipima. Niba birimo icyuma, niba bifite ikintu gishobora kubangamira imbaraga za rukuruzi, cyangwa niba bidashobora gukurwaho, ushobora kutashobora gukora iki kizamini. Bimwe muri ibyo bikoresho birimo:

Ni iki wakwitega mu gihe cy'ikizamini cya MEG?

Bitewe n'impamvu y'ikizamini cya MEG, hashobora kubaho impinduka nto mu buryo bwo gupima. Ubusanzwe, ibi ni byo bibaho:

1. Uzakenera gukuramo ibintu byose by'icyuma ku mubiri wawe no kwambara ikanzu y'abaganga .

2. Impinja n'abana bato bashobora gukenera guhabwa ikinya cyangwa ikinya rusange kugira ngo babashe kuguma bahagaze mu gihe cyo gupimwa kwa MEG. Niba bimeze bityo, umuyoboro muto witwa IV uzashyirwa mu mutsi uri mu kuboko kugira ngo batange umuti.

3. Kugira ngo umuganga arebe neza ko umutwe wawe uri mu mwanya ukwiye ugereranije n'ibyuma bipima ku ngofero, ashobora gushyira ku mutwe wawe uduce duto dutatu cyangwa tune (`positioning coils`) by'agateganyo ahantu hatatu cyangwa hane . Hanyuma, bazapima aho uduce duto tw'uduce duto duherereye akoresheje igikoresho cyihariye gisa n'inkoni.

4. Kugira ngo umuganga akureho ibimenyetso bito bya rukuruzi bishobora kuba bifatanye n'umubiri wawe mu bidukikije, azamura igikoresho kizengurutse (cyitwa `degausser`) hejuru y'umubiri wawe.

5. Hanyuma, uzategekwa kuryama ku meza yo gupimisha yimukanwa, cyangwa ugashyirwa mu ntebe yihariye ihujwe n'imashini ya `(MEG)`.

6. Muganga azashyira ingofero ifite sensor za `(MEG)` ku mutwe wawe. Iyo wambaye iyi ngofero, uzumva ufite `claustrophobia` nke cyane. Ikintu cy'ingenzi ni uko ushyira umutwe wawe mu ngofero kugira ngo ubwonko bwawe bube hafi cyane y'ibyuma bipima `(MEG)`.

7. Bitewe n'impamvu yo gupimwa, ushobora gusabwa kuryama ntuje cyangwa kuryama.Ni ingenzi cyane kugerageza kugumana umutwe mu gihe cy'ikizamini.

8. Kugira ngo umenye neza ibice by'ubwonko bwawe, ikizamini kigusaba gukora imirimo imwe n'imwe. Urugero, gusoma amagambo kuri ecran, gusubiza ibibazo, cyangwa gukanda buto inshuro nyinshi.

9. Hari igihe umuganga ashobora kuguha amashanyarazi make kugira ngo apime uko ubwonko bwawe bubyitwaramo. Bizagutera kumva urimo gukururwa, ariko ntacyo bizagutwara.

10. Iyo umuganga amaze kubona amakuru yose akeneye, isuzuma riba rirangiye. Inzobere isesengura raporo.

Mu gihe cyo gupima, ntuzumva ikintu icyo ari cyo cyose kivuye kuri mashini ya MEG cyangwa ngo wumve ububabare ubwo aribwo bwose. Hari sisitemu yo guhamagara abantu mu buryo bubiri hamwe na sisitemu yo kugenzura amashusho mu cyumba, bityo ushobora kuvugana n'umuntu ukora ikizamini igihe icyo ari cyo cyose, maze bakakuvugisha.

Abaganga bamwe bashobora kandi gukora isuzuma rya EEG (electroencephalogram) cyangwa MRI (magnetic resonance imaging) hamwe n'ikizamini cya MEG. Muri icyo gihe, hashobora kongerwamo izindi ntambwe ku gikorwa.

Ikizamini cya ``(MEG)`` gisanzwe kimara isaha imwe cyangwa ebyiri kugira ngo kirangire.

Ni iki kibaho nyuma y'ikizamini cya MEG?

Niba wowe cyangwa umwana wawe mwahawe ikinya cyangwa ikinya cyo gusinziriza mu kizamini , muganga azagukurikirana iminota 30 kugeza ku masaha abiri nyuma yo gupimwa kugira ngo arebe neza ko mukize neza. Hari uzakenera kugutwara mu rugo.

Keretse uhawe imiti igabanya ububabare, nta gihe cyihariye cyo gukira gisabwa. Ushobora gusubira mu mirimo yawe isanzwe.

Ese hari ingaruka zishobora guterwa n'ikizamini cya MEG?

Iyi ni inkuru nziza cyane! Nta ngaruka zigaragara ubu mu kizamini cya `(MEG)`. Rero nta mpamvu yo gutinya.

Bitwara igihe kingana iki kugira ngo umuntu amenye ibisubizo by'ikizamini cya MEG?

Bishobora gufata inzobere iminsi myinshi, rimwe na rimwe ibyumweru, kugira ngo basuzume ibyavuye mu kizamini cya MEG. Ibi biterwa nuko abaganga bakoresha ibizamini bya MEG kugira ngo bategure kubagwa mu bwonko mu buryo bugoye, bishobora kuba birimo inzobere nyinshi zikorana.

Iyo bamaze gutegura gahunda, itsinda ry’abaganga bawe rizaganira nawe ku bisubizo byavuye mu bushakashatsi, riganire ku cyo gukora nyuma yaho.

Ni irihe tandukaniro riri hagati ya MEG na MRI?

Nubwo ibi byombi ari ibizamini by'ubwonko, hari itandukaniro rito.

• MRI (imaging magnetic resonance imaging) y'ubwonko ikoresha rukuruzi nini na mudasobwa kugira ngo ikore amashusho y'ubwonko bwawe ikusanya amakuru y'imiterere. Ni ukuvuga uko ubwonko bumeze n'uko ibice biteguye.
• MEG ikubiyemo kwandika imbaraga rukuruzi zituruka mu turemangingo tw’imitsi (neurons) mu bwonko bwawe hakoreshejwe amagana y’ibikoresho byihariye by’ikoranabuhanga na mudasobwa.Iyi mirima igaragara nk'imiraba y'ubwonko.

Abaganga bakunze guhuza MRI na MEG kugira ngo bakore igikorwa cyitwa Magnetic Source Imaging (MSI) . MSI ishobora gukora amakarita y'imikorere y'ubwonko.

MEG nayo itandukanye na MRI ikora (fMRI). FMRI ireba impinduka mu mikorere y'amaraso mu bice bimwe na bimwe by'ubwonko bwawe iyo ukora imirimo runaka. MEG na fMRI byombi bireba ibikorwa by'ubwonko, ariko MEG igaragaza ibice byihariye by'ibikorwa. FMRI igaragaza ibice rusange. Byongeye kandi, MEG irushaho kwerekana uburyo ibikorwa by'ubwonko bihinduka uko igihe kigenda (imiterere y'igihe).

Ni irihe tandukaniro riri hagati ya MEG na EEG?

Itandukaniro rya mbere hagati y'ibi bizamini bibiri byo gusuzuma indwara ni:

• EEG (electroencephalography) yandika imikorere y'amashanyarazi y'ubwonko bwawe.
• MEG yandika imbaraga za rukuruzi mu bwonko bwawe (ziterwa n'imikorere y'amashanyarazi).

Irindi tandukaniro ni uko MEG irushaho kumva no kwandika ibikorwa by'ubwonko kurusha EEG. Agahanga kawe n'amazi yo mu bwonko (CSF) bishobora guhindura imikorere y'amashanyarazi yanditswe na EEG. Ariko, izi ngingo ntizihindura imikorere y'imbaraga rukuruzi. Ibi biha MEG "ishusho" nziza y'ubwonko bwawe, cyangwa ubushobozi bwo kureba aho ibintu biherereye . Ni ukuvuga ko ishobora kwerekana ahantu hadasanzwe hakorerwa ibikorwa.

Hari igihe abaganga bakora EEG hamwe na MEG kugira ngo bakusanye amakuru arambuye ku bijyanye n'aho imikorere y'ubwonko ituruka.

Ubutumwa bw'ingenzi kuri wewe.

Nkuko mubibona, iki kizamini, cyitwa Magnetoencephalography (MEG), ni ikizamini cy'ingirakamaro cyane, kitangiza kandi cyizewe gifasha abaganga gupima ibice by'ubwonko bwawe no kumenya aho ibintu nk'ibicurane biherereye.

Niba wakoze ikizamini cya ``(MEG)`` kandi ukaba ufite impungenge cyangwa gushidikanya kuri cyo, menya neza ko wabaza muganga wawe. Barahari kugira ngo bagusubize ibibazo byawe kandi bagufashe. Ntugatinye ikintu icyo ari cyo cyose!
