Ingabe wena noma othile omaziyo unesifo esifana nesifo sokuwa? Noma wake wafuna ukwazi ukuthi zikuphi izingxenye ezibalulekile zobuchopho ezilawula inkulumo nokunyakaza ngaphambi kokuhlinzwa kobuchopho? Namuhla sikhuluma ngokuhlolwa okuthuthukisiwe kakhulu, okungenabuhlungu, nokuphephile odokotela abakusebenzisayo ezikhathini ezinjengalezi. Kubizwa ngokuthi i-MEG scan.
Kalula nje, iyini le MEG?
I-MEG, noma i-Magnetoencephalography, iwukuhlolwa okulinganisa amasimu kazibuthe amancane kakhulu akhiqizwa izimpawu zikagesi ezikhishwa amangqamuzana ethu obuchopho. Ukuze kube sobala, lena indlela yokudweba ubuchopho emisebenzini yethu yobuchopho.
Ingxenye engcono kakhulu ukuthi ayinabuhlungu nhlobo futhi ayihlaseli. Lokhu kusho ukuthi azikho izinaliti ezisetshenziswayo, akukho ukusikeka okwenziwe, futhi awuvezwa kunoma yimiphi imisebe, njenge-X-ray. I-MEG iyindlela ethuthuke kakhulu emhlabeni yokuqopha nokuhlola umsebenzi wobuchopho.
Kukuziphi izimo lapho kwenziwa khona ukuhlolwa kwe-MEG?
Odokotela bezinzwa kanye nodokotela abahlinza izinzwa basebenzisa lolu vivinyo lwe-MEG ngezizathu ezimbili eziyinhloko.
| Isikhathi sokusebenzisa isivivinyo | Inzuzo yakho |
|---|---|
| Ngesifo sokuwa | Lokhu kusetshenziselwa ukukhomba indawo eqondile ebuchosheni ebangela ukuxhuzula. Lolu lwazi lubaluleke kakhulu ekuhleleni ukuhlinzwa kwesifo sokuxhuzula. |
| Ukuhlinzwa kobuchopho | Ngaphambi kokuhlinzwa, njengokususa isimila sobuchopho, lokhu kuhlolwa kusiza ekutholeni kahle ukuthi izingxenye zobuchopho ezilawula imisebenzi ebalulekile njengokunyakaza, inkulumo, umbono kanye nokuthinta zitholakala kuphi. Lokhu kunganciphisa ingozi yokulimala kwalezi zindawo ezibalulekile ngesikhathi sokuhlinzwa. |
Ngaphezu kwalokho, i-MEG iyithuluzi elibalulekile ocwaningweni lwesayensi ukuze kuqondwe ngokujulile ukusebenza kobuchopho bomuntu.
Lo mshini usebenza kanjani?
Kulula kakhulu. Ama-neurons ebuchosheni bethu ayaxhumana ngokukhiqiza ama-voltage kagesi amancane kakhulu. Lapho la ma-electron egeleza, kudalwa insimu yamagnetic ewazungezile.
Umshini we-MEG usebenzisa izinzwa ezibucayi kakhulu ezingaphezu kuka-300 , ezibekwa kudivayisi efana nesigqoko osigqoka ekhanda lakho, ukuze uthole, urekhode, futhi uhlaziye lezi zinsimu zamagnetic. Lezi zinzwa zizwela kakhulu kangangokuthi zingakwazi ukuthola ngisho nezinsimu zamagnetic ezincane kakhulu ezivela ebuchosheni bethu. Lezi zinzwa zibizwa ngokuthi ama-SQUID (amadivayisi okuphazamisa i-quantum superconducting).
Lezi zinzwa kanye nesofthiwe yekhompyutha ekhethekile zisebenza ndawonye ukuqopha umsebenzi wobuchopho bakho nge-millisecond nge-millisecond, kungakhathaliseki ukuthi uhleli phansi noma wenza okuthile (isb., ubheka izithombe noma ufunda amagama). Okokugcina, lolu lwazi luhlanganiswa nesithombe sobuchopho bakho, esiboniswa esikrinini sekhompyutha njenge-"mephu" ekhombisa ukuthi yiziphi izingxenye zobuchopho bakho ezisebenzayo.
Ungalungiselela kanjani ukuhlolwa kwe-MEG?
Udokotela wakho uzokunikeza noma yimiphi imiyalelo ekhethekile oyidingayo ngaphambi kwalolu vivinyo.
- Udokotela uzobuza ukuthi udinga yini ukuyeka ukudla noma ukuphuza isikhashana ngaphambi kokuhlolwa.
- Bazokweluleka nangokuthi udinga ukwenza noma yiziphi izinguquko emithini oyiphuzayo.
- Ungafaki izimonyo ngosuku lokuhlolwa, futhi ungasebenzisi ijeli noma isifutho ezinweleni zakho. Lezi zinto zingaphazamisa imiphumela yokuhlolwa.
- Awukwazi ukuletha noma yiziphi izinto zensimbi egumbini lokuhlolwa. Lokhu kusho ukuthi kufanele ususe noma yibuphi ubucwebe, izibuko, izikhonkwane zezinwele, noma amabhulashi angaphansi kwentambo. Uma kudingeka, isibhedlela sizokunikeza ingubo ekhethekile yezokwelapha ongayigqoka.
Okubaluleke kakhulu: Qaphela izingxenye zensimbi emzimbeni wakho
Uma unemishini yezokwelapha efakwe unomphela emzimbeni wakho noma ngaphandle kwawo, kufanele nakanjani utshele udokotela wakho ngayo ngaphambi kokuhlolwa. Amanye amadivayisi aqukethe insimbi futhi angaphazamisa insimu yamagnetic, ngakho-ke ungase ungakwazi ukwenza lokhu kuhlolwa.
Uma unezinye zalezi zinto ezilandelayo emzimbeni wakho, ungakhohlwa ukutshela udokotela wakho ngakho.
| Imishini kanye nezimo okufanele uziqaphele |
|---|
| - Ama-valve enhliziyo okwenziwa |
| - Ama-Pacemaker noma ama-defibrillator enhliziyo |
| - Izinsiza zokuzwa (izifakelo ze-Cochlear) |
| - Izibambo zamazinyo zensimbi |
| - Izikhonkwane zensimbi, izikulufo, amapuleti, ama-stents, noma ama-staple afakwa emzimbeni ngemva kokuhlinzwa |
| - Izindawo zokufaka izidakamizwa ezifakwe |
| - Ama-coil athile ensimbi asetshenziselwa i-aneurysms yobuchopho |
| - Izitho zokwenziwa noma amalunga okufakelwa ensimbi |
Kwenzekani ngesikhathi sokuhlolwa?
Indlela ukuhlolwa kwe-MEG okwenziwa ngayo ingahluka kancane kuye ngesizathu salokho, kodwa ngokuvamile kwenzeka kanje.
1. Ukulungiselela: Uzosusa zonke izinto zensimbi emzimbeni wakho bese ugqoka ingubo yasesibhedlela.
2. Ezinganeni ezincane: Ezinganeni ezincane, kungadingeka ukuthi zinikeze umuthi wokudambisa noma umuthi wokubulala izinzwa ojwayelekile, njengoba kungaba nzima ukuthi zihlale zinganyakazi ngesikhathi sokuhlolwa.
3. Ukubeka: Linganisa indawo eqondile yekhanda lakho uma kuqhathaniswa nesigqoko, bese ufaka amakhoyili amathathu noma amane amancane okubeka ngetheyiphu yesikhashana ezindaweni ezintathu noma ezine ekhanda lakho.
4. Ukususa izimpawu zikamazibuthe: Okulandelayo, idivayisi eyindilinga ebizwa ngokuthi "i-degausser" ihanjiswa emzimbeni wakho ukuze kususwe izimpawu zikamazibuthe ezingafuneki okungenzeka ukuthi ziqongelelene endaweni yomzimba wakho.
5. Ukuhlala phansi ukuze uvivinywe: Uzobe usuhlaliswa esihlalweni esikhethekile esixhunywe emshinini we-MEG, noma uzolaliswa embhedeni.
6. Ukugqoka isigqoko sokuzivikela:Manje, isigqoko esinezinzwa ze-MEG sibekwe ekhanda lakho. Lokhu kunciphisa ingozi ye-claustrophobia. Ukuze uthole imiphumela emihle kakhulu, gcina ikhanda lakho liseduze nesigqoko ngangokunokwenzeka.
7. Ngesikhathi sokuhlolwa: Ngezinye izikhathi uzocelwa ukuthi uhlale phansi unganyakazi, futhi ungase ulale. Ekuhlolweni kobuchopho, uzocelwa ukuthi ufunde amagama esikrinini, uphendule imibuzo, noma wenze imisebenzi emincane, njengokucindezela inkinobho. Ngezinye izikhathi, umunwe wakho unganikezwa isikhuthazo esincane sikagesi ukuze ulinganise ukuthi ubuchopho bakho busabela kanjani. Lokhu kungase kuzwakale njengokukhafula okuncane, kodwa akubuhlungu.
8. Ukuxhumana: Igumbi lokuhlola line-intercom kanye nesistimu yevidiyo, ngakho-ke ungakhuluma nochwepheshe wokuhlola nganoma yisiphi isikhathi.
Lonke lolu vivinyo luthatha cishe ihora elilodwa noma amabili.
Kwenzekani ngemva kokuhlolwa?
Uma wena noma ingane yakho ninikezwe umuthi wokudambisa ubuhlungu, abasebenzi bezokwelapha bazoniqapha cishe isigamu sehora kuya emahoreni amabili. Uzodinga umuntu ozokusiza ukuthi uye ekhaya.
Uma ungaphuzi utshwala, akukho nkinga. Ungaqhubeka nemisebenzi yakho evamile ngokushesha nje lapho isivivinyo sesiphelile.
Azikho izingozi ezaziwayo ezihlobene nokuhlolwa kwe-MEG. Kuwukuhlolwa okuphephile kakhulu.
Uyini umehluko phakathi kwe-MEG, i-MRI kanye ne-EEG?
Nakuba zonke lezi zivivinyo ezintathu zenziwa ebuchosheni, ulwazi abalulinganisayo nabasinika lona luhlukile.
| Ukuhlolwa | Kulinganiswa ini? | Isici esiyinhloko |
|---|---|---|
| I-MEG | Amasimu kazibuthe akhiqizwa umsebenzi kagesi ebuchosheni. | Indawo eqondile kanye nesikhathi somsebenzi wobuchopho kuboniswa ngokunemba okuphezulu. Akukho ukuphazamiseka kwesignali okuvela ekhanda. |
| I-MRI (Umfanekiso Wokuqabulana Kwamagnetic) | Isakhiwo sobuchopho kanye nezicubu . | Inikeza isithombe esicacile sokuthi ubuchopho bubukeka kanjani, izingxenye zabo, amathumba, njll. Ayilinganisi ukusebenza. |
| I-EEG (i-Electroencephalogram) | Umsebenzi kagesi wobuchopho. | Izimpawu zikagesi zingaphambuka kancane njengoba zidlula ekhanda nakwezinye izicubu, futhi aziqondile njenge-MEG. |
Ngezinye izikhathi odokotela bahlanganisa ulwazi oluvela kokubili ekuhlolweni kwe-MEG kanye ne-MRI ukuze bakhe imephu yokusebenza kobuchopho. Lokhu kubizwa ngokuthi i-MSI (Magnetic Source Imaging).
Umlayezo Wokuya Nawe Ekhaya
- I-MEG iyisivivinyo esingenabuhlungu, esingenamisebe, futhi esiphephile kakhulu esibala ukusebenza kobuchopho.
- Lokhu kusetshenziselwa kakhulu ukukhomba indawo eqondile yokuquleka kanye nokuhlinzwa kobuchopho okuhleliwe .
- Kubalulekile ukuthi wazise udokotela nganoma yimaphi amadivayisi ensimbi afakwe emzimbeni wakho ngaphambi kokuhlolwa.
- Ukuhlolwa kwe-MEG kukwazi kakhulu ukuhlonza indawo yokusebenza kobuchopho ngokunembile kune-EEG.
- Uma udokotela wakho encoma lokhu kuhlolwa, ungesabi ukubuza udokotela wakho noma yimiphi imibuzo onayo.
