Ake sifunde ngokuhlolwa kwe-Magnetoencephalography (MEG), okuchaza umsebenzi wobuchopho bakho.

Wake wezwa ngalolu vivinyo olubizwa ngokuthi `(Magnetoencephalography)` noma `(MEG)`? Mhlawumbe wena noma othile omaziyo utshelwe udokotela ukuthi enze lokhu. Ungesabi, empeleni lena indlela yokuhlola ethuthuke kakhulu, futhi ayilimazi imizimba yethu nganoma iyiphi indlela. Namuhla, sizoxoxa ngalolu vivinyo `(MEG)` ngendlela elula ongayiqonda.

Kuyini i-MEG? Kulula kakhulu!

Kalula nje, i -`(MEG)` iyisivivinyo esilinganisa amasimu kazibuthe akhiqizwa yimisinga kagesi ebuchosheni bakho. Cabanga nje, kufana nemiyalezo emincane kagesi eshintshaniswa ngaphakathi kobuchopho bethu. Logesi udala insimu kazibuthe. Lawo masimu kazibuthe yiwo lo mshini we-`(MEG)` olinganisa.

Lokhu kuvumela odokotela ukuthi babone umsebenzi wobuchopho bakho njengemephu. Lokhu kusiza kakhulu ezimweni ezifana nesifo sokuwa , lapho bengakwazi khona ukukhomba ngqo ukuthi ukuquleka kobuchopho kuvela kuphi.

Into ebaluleke kakhulu ukuthi lokhu kuhlolwa akulimazi umzimba (`okungenasihlaseli`). Lokho kusho ukuthi awudingi ukufaka izinaliti noma ukwenza ukuhlinzwa. Awuvezwa emisebeni efana `(X-ray)`. Phakathi kwezindlela zamanje, le `(MEG)` iyindlela ethuthuke kakhulu yokuqopha nokuhlaziya umsebenzi wobuchopho.

Yiziphi izindlela zokusebenzisa ukuhlolwa kwe-MEG?

Odokotela bezinzwa kanye nodokotela abahlinza izinzwa basebenzisa lokhu kuhlolwa (MEG) ngezizathu ezimbili eziyinhloko:

1. Hlola umsebenzi wobuchopho bakho ozenzakalelayo. Lokhu kungasiza ekutholeni indawo eqondile yokuxhuzula kumuntu onesifo sokuxhuzula. Lokhu kubaluleke kakhulu ekuhleleni ukuhlinzwa kwesifo sokuxhuzula. Cabanga nje uSamantha enesifo sokuxhuzula futhi udinga ukuhlinzwa. Bese odokotela benza i-MEG ukuze babone ukuthi isifo sokuxhuzula sivela kuyiphi ingxenye yobuchopho, bese beqondisa leyo ngxenye kuphela bese benza ukuhlinzwa.

2. Hlola indlela ubuchopho bakho obusabela ngayo ezintweni ezibangela ukucindezeleka kwangaphandle.Lokhu kuvumela ukudwetshwa kwemephu enembile yezindawo zobuchopho ezihlobene nokunyakaza, imizwa, ulimi, umbono, njll. Lokhu kuwusizo kakhulu ekuhleleni ukuhlinzwa kwabantu abanezimila zobuchopho.

Ngaphezu kwalokho, i-MEG iphinde ibe yingxenye ebaluleke kakhulu yocwaningo lwezinzwa nolwengqondo, lapho ososayensi benza khona ucwaningo ukuze bathole ukuqonda okujulile ngokusebenza kobuchopho bomuntu.

Ukuhlolwa kwe-MEG kusebenza kanjani? Kungokwesayensi kancane, kodwa kulula!

Amaseli ezinzwa ebuchosheni bethu ayaxhumana ngokukhiqiza ama-voltage amancane kagesi. Uma la mandla kagesi egeleza, adala insimu yamagnetic. Lawo mandla kazibuthe ayatholwa, aqoshwe, futhi ahlaziywe yizinzwa zamagnetic ezizwelayo emshinini we-MEG.

Kodwa, le nsimu yamagnetic ekhiqizwa ubuchopho bakho ibuthakathaka kakhulu. Ngakho-ke, kudingeka izinhlelo ezikhethekile zezinzwa ukuze kubanjwe leso siginali. Lezi zinhlelo zakhiwe ngamakhoyili amancane, anesinqumo esiphezulu. Lawa axhunywe kumadivayisi abizwa ngokuthi ama-SQUID - amadivayisi okuphazamisa i-quantum aqhubayo. Kunezinzwa ezingaphezu kuka-300 ngaphakathi kwedivayisi efana nesigqoko osigqoka ngesikhathi sokuhlolwa.

Ngesikhathi ulele unganyakazi, ngezinye izikhathi ulalele imisindo, noma wenza okuthile okufana nokubuka izithombe, izinzwa ezikulesi sigqoko, kanye nesofthiwe yekhompyutha ekhethekile, zisebenza ndawonye ukuthola nokurekhoda umsebenzi wamaseli ezinzwa. I-MEG iqopha izimpawu ezijwayelekile nezingavamile ebuchosheni njalo ngemizuzwana emi-3 . Lawa masimu kazibuthe abese eboniswa esikrinini sekhompyutha kanye nesithombe sokwakheka kobuchopho bakho. Lokhu kukuvumela ukuthi "ukwazi" ukuthola ukuthi imisebenzi ethile yobuchopho iqala kuphi nokuthi yenzeka nini.

Ulungiselela kanjani ukuhlolwa kwe-MEG?

Uma uhlolwa i-MEG, udokotela wakho uzokutshela uma kudingeka uyeke ukudla noma ukuphuza ngaphambi kokuhlolwa. Uzokutshela futhi uma kudingeka wenze noma yiziphi izinguquko emithini yakho noma endleleni yakho yansuku zonke.

• Ungafaki izimonyo noma imikhiqizo yezinwele ngosuku lokuhlolwa. Kungase kuphazamise ukuhlolwa.
• Futhi, awukwazi ukuletha noma yiziphi izinto zensimbi egumbini lokuhlolwa. Isibonelo, ubucwebe, izibuko, izikhonkwane zezinwele, amabhulashi angaphansi kwensimbi, kanye nezingubo ezinezesekeli zensimbi. Uma kudingeka, uzonikezwa ingubo yezokwelapha ozoyigqoka.

Okubalulekile:Uma unemishini yezokwelapha efakwe ngaphakathi noma ngaphandle komzimba wakho, kufanele utshele udokotela wakho ngaphambi kokuhlolwa. Uma inensimbi, uma inanoma yini engaphazamisa amandla kazibuthe, noma uma ingenakususwa, ungase ungakwazi ukwenza lokhu kuhlolwa. Amanye ala madivayisi afaka:

>

* Ama-valve enhliziyo okwenziwa.

* Izitho zokwenziwa noma amalunga okufakelwa ensimbi.

* Ama-defibrillator enhliziyo kanye nama-pacemaker.

* Izinkinga ezithile zobuchopho.

* Ama-coil athile ensimbi afakwa ngaphakathi kwemithambo yegazi.

* Izimila ze-Cochlear.

* Amachweba okufaka imithi afakwe.

* Izinto ezivuselela imizwa ezifakwe.

* Izibambo zamazinyo zensimbi.

* Izikhonkwane zensimbi, izikulufo, amapuleti, ama-stents noma izinto zokuhlinzwa.

* Ama-shunt angahlelwa.

Yini ongayilindela ngesikhathi sokuhlolwa kwe-MEG?

Kuye ngesizathu sokuhlolwa kwe-MEG, kungase kube nokwehluka okuncane enkambisweni yokuhlola. Ngokuvamile, yilokhu okwenzekayo:

1. Kuzodingeka ususe zonke izinto zensimbi emzimbeni wakho bese ugqoka ingubo yezokwelapha .

2. Izinsana nezingane ezincane kungadingeka zinikezwe umuthi wokudambisa ubuhlungu noma umuthi wokubulala izinzwa ojwayelekile ukuze zihlale zinganyakazi ngesikhathi sokuhlolwa kwe-MEG. Uma kunjalo, kuzofakwa ithubhu elincane elibizwa ngokuthi i-IV emthanjeni ongalweni ukuze kunikezwe umuthi.

3. Ukuze aqinisekise ukuthi ikhanda lakho lisendaweni efanele uma kuqhathaniswa nezinzwa ezikulesi sigqoko, udokotela angase anamathisele okwesikhashana ama-coil amathathu noma amane amancane (`ama-coil okubeka`) ekhanda lakho ezindaweni ezintathu noma ezine . Bese, bazolinganisa izindawo zala ma-coil ngedivayisi ekhethekile 'efana nenduku'.

4. Ukuze asuse izimpawu ezincane zikagesi ezingase zixhunywe emzimbeni wakho endaweni ezungezile, udokotela uzohambisa idivayisi eyindilinga (ebizwa ngokuthi i-`degausser`) phezu komzimba wakho.

5. Ngemuva kwalokho, uzolaliswa etafuleni lokuhlola elihambayo, noma ubekwe esihlalweni esikhethekile esixhunywe emshinini we-`(MEG)`.

6. Udokotela uzofaka isigqoko esinezinzwa ze-`(MEG)` ekhanda lakho. Uma ufaka lesi sigqoko, uzozizwa ungenaso i-`claustrophobia` encane kakhulu. Into ebaluleke kakhulu ukuthi ufake ikhanda lakho ngaphakathi kwesigqoko ukuze ubuchopho bakho busondele kakhulu ezinzwa zomshini we-`(MEG)`.

7. Kuye ngesizathu sokuhlolwa, ungase ucelwe ukuthi ulale unganyakazi noma ulale phansi.Kubaluleke kakhulu ukuzama ukugcina ikhanda lakho linganyakazi ngesikhathi sokuhlolwa.

8. Ukuze kudwetshwe izindawo ezizwayo zobuchopho bakho, ukuhlolwa kukucela ukuthi wenze imisebenzi ethile. Isibonelo, ukufunda amagama esikrinini, ukuphendula imibuzo, noma ukucindezela inkinobho ngokuphindaphindiwe.

9. Ngezinye izikhathi, udokotela angakunika ugesi omncane ukuze alinganise ukuthi ubuchopho bakho busabela kanjani kuwo. Kuzokwenza uzizwe sengathi uyakhangwa, kodwa ngeke kube buhlungu.

10. Uma udokotela esenolwazi lonke aludingayo, ukuhlolwa kuyaqedwa. Uchwepheshe ube esehlaziya imibiko.

Ngesikhathi sokuhlolwa, ngeke uzwe noma yimuphi umuzwa ovela emshinini we-MEG noma uzwe noma yimuphi ubuhlungu. Kukhona uhlelo lwe-intercom olunezindlela ezimbili kanye nohlelo lokuqapha ividiyo egumbini, ngakho ungakhuluma nomuntu owenza ukuhlolwa nganoma yisiphi isikhathi, futhi angakhuluma nawe.

Abanye odokotela bangase benze ne-EEG (electroencephalogram) noma i-MRI (magnetic resonance imaging) kanye nokuhlolwa kwe-MEG. Kuleso simo, kungase kwenezelwe izinyathelo ezengeziwe enkambisweni.

Ukuhlolwa kwe-``(MEG)`` kuvame ukuthatha cishe ihora noma amabili ukuqedwa.

Kwenzekani ngemva kokuhlolwa kwe-MEG?

Uma wena noma ingane yakho ninikezwe umuthi wokudambisa noma wokubulala izinzwa ngesikhathi sokuhlolwa , udokotela uzokugada imizuzu engama-30 kuya emahoreni amabili ngemva kokuhlolwa ukuqinisekisa ukuthi uyalulama kahle. Kuzodingeka othile akuyise ekhaya ngemoto.

Ngaphandle kokuthi unikezwe imithi yokudambisa ubuhlungu, asikho isikhathi esikhethekile sokululama esidingekayo. Ungaqhubeka nemisebenzi yakho evamile.

Ingabe zikhona izingozi zokuhlolwa kwe-MEG?

Lezi yizindaba ezinhle kakhulu! Azikho izingozi ezitholakala njengamanje ngokuhlolwa kwe-`(MEG)`. Ngakho-ke asikho isizathu sokwesaba.

Kuthatha isikhathi esingakanani ukwazi imiphumela yokuhlolwa kwe-MEG?

Kungathatha ochwepheshe izinsuku eziningana, ngezinye izikhathi amasonto, ukubukeza imiphumela yokuhlolwa kwe-MEG. Lokhu kungenxa yokuthi odokotela basebenzisa ukuhlolwa kwe-MEG ukuhlela ukuhlinzwa kobuchopho okuyinkimbinkimbi, okungabandakanya ochwepheshe abaningana abasebenza ndawonye.

Uma sebesungule uhlelo, ithimba lakho lezokwelapha lizoxoxa nawe ngemiphumela bese lixoxa ngokuthi yini okufanele uyenze ngokulandelayo.

Uyini umehluko phakathi kwe-MEG ne-MRI?

Nakuba kokubili lokhu kuyizilingo zobuchopho, kunomehluko omncane.

• I-MRI (magnetic resonance imaging) yobuchopho isebenzisa i-magnet enkulu kanye nekhompyutha ukudala izithombe zobuchopho bakho ngokuqoqa ulwazi lwesakhiwo. Okusho ukuthi, ubuchopho bubukeka kanjani nokuthi izingxenye zihlelwe kanjani.
• I-MEG ihilela ukuqopha amasimu kazibuthe avela kumaseli ezinzwa (ama-neurons) ebuchosheni bakho usebenzisa amakhulu ezinzwa ezikhethekile kanye nekhompyutha.Lezi zinsimu zibonakala njengamaza obuchopho.

Odokotela bavame ukuhlanganisa i-MRI ne-MEG ukuze benze inqubo ebizwa ngokuthi i-Magnetic Source Imaging (MSI) . I-MSI ingakha amamephu asebenzayo okusebenza kobuchopho.

I-MEG nayo ihlukile kwi -MRI esebenzayo (fMRI). I-fMRI ibheka izinguquko ekugelezeni kwegazi ezindaweni ezithile zobuchopho bakho uma wenza imisebenzi ethile. Kokubili i-MEG ne-fMRI kubheka umsebenzi wobuchopho, kodwa i-MEG ikhombisa izindawo ezithile zomsebenzi. I-fMRI ikhombisa izindawo ezijwayelekile. Ngaphezu kwalokho, i-MEG ingcono ekuboniseni ukuthi umsebenzi wobuchopho ushintsha kanjani ngokuhamba kwesikhathi (izici zesikhashana).

Uyini umehluko phakathi kwe-MEG ne-EEG?

Umehluko wokuqala phakathi kwalezi zivivinyo ezimbili zokuxilonga ngu:

• I-EEG (i-electroencephalography) iqopha umsebenzi kagesi wobuchopho bakho.
• I-MEG iqopha amasimu kazibuthe ebuchosheni bakho (abangelwa umsebenzi kagesi).

Omunye umehluko ukuthi i-MEG inozwela kakhulu futhi inembile ekuqopheni umsebenzi wobuchopho kune-EEG. Ugebhezi lwakho kanye noketshezi lomgogodla (CSF) kungaphambukisa umsebenzi kagesi oqoshwe yi-EEG. Kodwa-ke, lezi zicubu aziphambukisi amasimu kazibuthe. Lokhu kunikeza i-MEG "isithombe" esingcono sobuchopho bakho, noma isixazululo sendawo . Okusho ukuthi, ingakhomba izindawo zomsebenzi ongajwayelekile.

Ngezinye izikhathi odokotela benza i-EEG kanye ne-MEG ukuze baqoqe ulwazi olwengeziwe mayelana nokuthi umsebenzi wobuchopho uvelaphi.

Umyalezo obalulekile kuwe.

Njengoba ubona, lolu vivinyo, olubizwa nge-Magnetoencephalography (MEG), luwuvivinyo oluwusizo kakhulu, olungenangozi, noluphephile olusiza odokotela ukuthi babhale izindawo ezibucayi zobuchopho bakho futhi bathole indawo eqondile yezinto ezifana nokuxhuzula.

Uma une-"(MEG)`` yokuhlola futhi unemibuzo noma ukungabaza ngakho, qiniseka ukuthi ubuza udokotela wakho. Bakhona ukuphendula imibuzo yakho futhi bakusekele. Ungesabi lutho!
