Kodi inuyo kapena munthu amene mumamudziwa ali ndi vuto monga khunyu? Kapena munayamba mwafuna kudziwa komwe mbali zofunika za ubongo zomwe zimalamulira kulankhula ndi kuyenda zili musanachite opaleshoni ya ubongo? Lero tikulankhula za mayeso apamwamba kwambiri, osapweteka, komanso otetezeka omwe madokotala amagwiritsa ntchito nthawi ngati izi. Amatchedwa MEG scan.
Mwachidule, kodi MEG iyi ndi chiyani?
MEG, kapena Magnetoencephalography, ndi mayeso omwe amayesa mphamvu zamaginito zobisika kwambiri zopangidwa ndi zizindikiro zamagetsi zomwe maselo athu a ubongo amapereka. Kunena zoona, iyi ndi njira yowunikira ubongo wathu.
Chabwino kwambiri n'chakuti sichipweteka konse komanso sichivulaza. Izi zikutanthauza kuti palibe singano zomwe zimagwiritsidwa ntchito, palibe kudula komwe kumachitika, ndipo simukumana ndi ma radiation aliwonse, monga X-ray. MEG ndiyo njira yapamwamba kwambiri padziko lonse lapansi yojambulira ndikuwunika momwe ubongo ukugwira ntchito.
Kodi mayeso a MEG amachitidwa nthawi ziti?
Madokotala a mitsempha ndi opaleshoni ya mitsempha amagwiritsa ntchito mayeso a MEG awa pazifukwa ziwiri zazikulu.
| Nthawi yogwiritsira ntchito mayesowa | Ubwino wake |
|---|---|
| Kwa khunyu | Izi zimagwiritsidwa ntchito podziwa malo enieni muubongo omwe amayambitsa khunyu. Izi ndizofunikira kwambiri pokonzekera opaleshoni ya khunyu. |
| Kwa opaleshoni ya ubongo | Opaleshoni isanachitike, monga kuchotsa chotupa cha muubongo, mayesowa amathandiza kudziwa komwe kuli ziwalo za ubongo zomwe zimayang'anira ntchito zofunika monga kuyenda, kulankhula, kuona, ndi kukhudza. Izi zitha kuchepetsa chiopsezo cha kuwonongeka kwa madera ofunikira awa panthawi ya opaleshoni. |
Kuphatikiza apo, MEG ndi chida chofunikira kwambiri pa kafukufuku wa sayansi kuti timvetsetse bwino momwe ubongo wa munthu umagwirira ntchito.
Kodi makina awa amagwira ntchito bwanji?
Ndi zophweka kwambiri. Ma neuron muubongo wathu amalankhulana wina ndi mnzake popanga ma voltage ang'onoang'ono amagetsi. Pamene mafunde amagetsi awa akuyenda, mphamvu ya maginito imapangidwa mozungulira iwo.
Makina a MEG amagwiritsa ntchito masensa opitilira 300 ozindikira kwambiri , omwe amaikidwa pa chipangizo chonga chisoti chomwe mumavala pamutu panu, kuti azindikire, kujambula, ndikuwunika mphamvu zamaginito izi. Masensawa ndi ozindikira kwambiri kotero kuti amatha kutenga ngakhale mphamvu zazing'ono kwambiri zamaginito zochokera muubongo wathu. Masensawa amatchedwa SQUIDs (zipangizo zosokoneza za quantum).
Masensa awa ndi mapulogalamu apadera apakompyuta amagwira ntchito limodzi kuti alembe zochitika muubongo wanu millisecond ndi millisecond, kaya mukukhala chete kapena mukuchita china chake (monga kuyang'ana zithunzi kapena kuwerenga mawu). Pomaliza, chidziwitsochi chimaphatikizidwa ndi chithunzi cha ubongo wanu, chomwe chimawonetsedwa pazenera la kompyuta ngati "mapu" osonyeza magawo a ubongo wanu omwe akugwira ntchito.
Kodi mungakonzekere bwanji mayeso a MEG?
Dokotala wanu adzakupatsani malangizo apadera omwe mukufuna musanayese mayesowa.
- Dokotala adzakufunsani ngati muyenera kupewa kudya kapena kumwa kwa kanthawi musanayesedwe.
- Adzakulangizaninso ngati mukufunika kusintha mankhwala omwe mukumwa.
- Musamadzole zodzoladzola pa tsiku loyesa, ndipo musagwiritse ntchito gel kapena spray pa tsitsi lanu. Zinthu zimenezi zingasokoneze zotsatira za mayeso.
- Simungathe kubweretsa zinthu zachitsulo m'chipinda choyezetsera. Izi zikutanthauza kuti muyenera kuchotsa zodzikongoletsera, magalasi, mapini a tsitsi, kapena mabra apansi pa waya. Ngati pakufunika kutero, chipatala chidzakupatsani diresi lapadera lachipatala kuti muvale.
Chofunika kwambiri: Dziwani ziwalo zachitsulo m'thupi lanu
Ngati muli ndi zipangizo zachipatala zomwe zaikidwa mkati kapena kunja kwa thupi lanu kwamuyaya, muyenera kuuza dokotala wanu za izo musanayesedwe. Zipangizo zina zimakhala ndi chitsulo ndipo zingasokoneze mphamvu ya maginito, kotero simungathe kuchita mayesowa.
Ngati muli ndi zotsatirazi m'thupi lanu, musaiwale kuuza dokotala wanu za izi.
| Zipangizo ndi mikhalidwe yoti muzindikire |
|---|
| - Ma valve a mtima opangidwa |
| - Othandizira pacemaker kapena oletsa mtima |
| - Zipangizo zothandizira kumva (zopangira cochlear) |
| - Zothandizira mano achitsulo |
| - Mapini achitsulo, zomangira, mbale, ma stenti, kapena zinthu zofunika zomwe zimayikidwa m'thupi pambuyo pa opaleshoni |
| - Madoko olowetsera mankhwala opangidwa |
| - Ma coil ena achitsulo omwe amagwiritsidwa ntchito pa aneurysms ya ubongo |
| - Ziwalo zopangira kapena zolumikizira zachitsulo zopangira |
Kodi chimachitika ndi chiyani panthawi ya mayeso?
Momwe mayeso a MEG amachitikira zimatha kusiyana pang'ono kutengera chifukwa chake, koma nthawi zambiri zimakhala motere.
1. Kukonzekera: Mudzachotsa zinthu zonse zachitsulo m'thupi lanu ndikuvala diresi lachipatala.
2. Kwa ana aang'ono: Kwa ana aang'ono, zingakhale zofunikira kupereka mankhwala oletsa ululu kapena mankhwala oletsa ululu, chifukwa zingakhale zovuta kuti akhale chete panthawi yoyezetsa.
3. Malo Oyikira: Yesani malo enieni a mutu wanu poyerekeza ndi chisoti, ndipo ikani zozungulira zitatu kapena zinayi zazing'ono zoyikira ndi tepi yanthawi yochepa pamalo atatu kapena anayi pamutu panu.
4. Kuchotsa zizindikiro zamaginito: Kenako, chipangizo chozungulira chotchedwa "degausser" chimayendetsedwa mozungulira thupi lanu kuti chichotse zizindikiro zamaginito zosafunikira zomwe zingakhale zitasonkhana m'thupi lanu.
5. Kukhala pansi pa mayeso: Kenako mudzalamulidwa kukhala pampando wapadera wolumikizidwa ndi makina a MEG, kapena mudzalamulidwa kugona pabedi.
6. Kuvala chisoti:Tsopano, chisoti chokhala ndi masensa a MEG chayikidwa pamutu panu. Izi zimachepetsa chiopsezo cha claustrophobia. Kuti mupeze zotsatira zabwino, sungani mutu wanu pafupi ndi chisoti momwe mungathere.
7. Pa nthawi ya mayeso: Nthawi zina mudzapemphedwa kukhala chete, ndipo mwina mungagone. Pakujambula ubongo, mudzapemphedwa kuwerenga mawu pa sikirini, kuyankha mafunso, kapena kuchita ntchito zazing'ono, monga kukanikiza batani. Nthawi zina, chala chanu chingapatsidwe mphamvu yamagetsi kuti chiyese momwe ubongo wanu umayankhira. Izi zingamveke ngati kukugwedezani pang'ono, koma sizipweteka.
8. Kulankhulana: Chipinda choyesera chili ndi intercom ndi makina ojambulira makanema, kotero mutha kulankhula ndi katswiri woyesa nthawi iliyonse.
Mayeso onsewa amatenga ola limodzi kapena awiri.
Kodi chimachitika ndi chiyani pambuyo pa mayeso?
Ngati inu kapena mwana wanu munapatsidwa mankhwala oletsa ululu, ogwira ntchito zachipatala adzakuyang'anirani kwa pafupifupi theka la ola mpaka maola awiri. Mudzafunika wina woti akuthandizeni kupita kunyumba.
Ngati simunamwe mankhwala oletsa ululu, palibe vuto. Mutha kupitiriza ndi zochita zanu zachizolowezi mayeso akangotha.
Palibe zoopsa zodziwika zokhudzana ndi mayeso a MEG. Ndi mayeso otetezeka kwambiri.
Kodi kusiyana pakati pa MEG, MRI ndi EEG ndi kotani?
Ngakhale kuti mayeso onse atatuwa amachitikira ku ubongo, chidziwitso chomwe amachiyesa ndi kutipatsa n’chosiyana.
| Mayeso | Kodi kuyezedwa nchiyani? | Mbali yaikulu |
|---|---|---|
| MEG | Maginito opangidwa ndi ntchito zamagetsi muubongo. | Malo enieni ndi nthawi yomwe ubongo umagwira ntchito zimawonetsedwa molondola kwambiri. Palibe kusokonekera kwa chizindikiro kuchokera ku chigaza. |
| MRI (Kujambula kwa Magnetic Resonance) | Kapangidwe ka ubongo ndi minofu . | Imapereka chithunzi chomveka bwino cha momwe ubongo umaonekera, ziwalo zake, zotupa, ndi zina zotero. Siimayesa momwe ubongo umagwirira ntchito. |
| EEG (Electroencephalogram) | Ntchito yamagetsi ya ubongo. | Zizindikiro zamagetsi zimatha kusokonekera pang'ono zikamadutsa m'chigaza ndi minofu ina, ndipo sizili zolondola ngati MEG. |
Nthawi zina madokotala amaphatikiza chidziwitso kuchokera ku mayeso a MEG ndi MRI kuti apange mapu ogwira ntchito a ubongo. Izi zimatchedwa MSI (Magnetic Source Imaging).
Uthenga Wopita Nawo Kunyumba
- MEG ndi njira yoyesera yopanda ululu, yopanda poizoni, komanso yotetezeka kwambiri yomwe imawonetsa momwe ubongo umagwirira ntchito.
- Izi zimagwiritsidwa ntchito makamaka pofufuza malo enieni a khunyu ndikukonzekera opaleshoni ya ubongo .
- Ndikofunikira kuti mudziwitse dokotala za zipangizo zilizonse zachitsulo zomwe zaikidwa m'thupi lanu musanayesedwe.
- Kuyesa kwa MEG kumatha kuzindikira bwino komwe ubongo ukugwira ntchito kuposa EEG.
- Ngati dokotala wanu akulangizani mtundu uwu wa mayeso, musaope kufunsa dokotala wanu mafunso aliwonse omwe muli nawo.
