Ngatingodzidzai nezve fMRI scan (Functional MRI), iyo inotarisa nzvimbo dzinoshanda mukati meuropi.

Fungidzira kuti iwe kana mumwe munhu waunoziva anoda kuvhiyiwa uropi. Chinhu chekutanga chatinofunga ndechekuti, "Ah, vanachiremba, unoziva sei kushanda pasina kukuvadza nzvimbo dzakakosha pakutaura, kufamba, uye kurangarira?" Mubvunzo mukuru uyu. Nhasi tiri kutaura nezve scan yakakosha inobatsira nazvo, iyo inoratidza mepu 'mhenyu' yemukati meuropi. Izvi zvinonzi fMRI, kana Functional MRI scan.

Zvichitaurwa zviri nyore, chii chinonzi fMRI?

Ungave wakambonzwa nezveMRI scan. Inotora mifananidzo yakajeka yezvikamu zvitatu (3D) zvenhengo dziri mukati memiviri yedu. Haishandise X-ray kana radiation senge CT scans. Saka hapana chekutya.

Zvino, fMRI iongororo yakakosha inoshandisa muchina weMRI mumwe chete. Asi chinoshamisa pane iyi ndechekuti, pamusoro pekutora mufananidzo weuropi, inoratidzawo kuti ndeapi zvikamu zveuropi zvinoshanda panguva iyoyo.

Zvinoshanda seizvi: Kana chikamu cheuropi hwedu chichishanda, sepatinenge tichitaura, tichifunga, kana kufambisa ruoko rwedu, masero europi ari muchikamu ichocho anoda okisijeni yakawanda. Okisijeni yakawanda zvinoreva kuti ropa rakawanda rinoyerera. Muchina we fMRI unogona kuona kuti ropa rakawanda rinoyerera. Ipapo nzvimbo dziri kushanda dzinoonekwa dzakajeka pascan.

Ndezvipi zvinoshandiswa pakuongorora uku?

Kugadzira mepu yezvinoitika muuropi nenzira iyi kwakakosha zvikuru, kunyanya pakuronga kuvhiyiwa kweuropi. Kana uchida kuvhiyiwa, chiremba wepfungwa anogona kutarisa mepu iyi ye fMRI uye kuronga kuvhiyiwa pasina kukuvadza nzvimbo dzinodzora mabasa ako akakosha, akadai sekutaura nekufamba. Izvi zvinogona kuitwa pavakuru pamwe nevana.

Semuenzaniso, fungidzira kuti une bundu muuropi hwako. Bundu iri riri pedyo nechikamu cheuropi hwako chinodzora mafambiro aunoita minwe yako. Panguva yekuskena, unokumbirwa kufambisa minwe yako. Mufananidzo we fMRI unoratidza nzvimbo chaiyo yauri kuita chiito ichocho, izvo zvinovhenekera. Ipapo chiremba anovhiya anoziva kubvisa bundu nokungwarira asingabate nzvimbo iyoyo.

Mamiriro makuru ekuda kuronga rudzi urwu ndeaya:

• Pfari: Kana munhu aine pfari isingadzoreki nemishonga, kana zvichidikanwa kuvhiyiwa, mashandiro europi anofanira kutariswa asati avhiyiwa.
• Matumbu emuuropi: Usati wavhiyiwa kubvisa tumbumbu tune kenza kana tusina njodzi.
• Kurapa nemwaranzi:Pakurapa uropi nemwaranzi, deredza kukuvara kwenhengo dzine hutano.
• Mushure mekurapwa: Tarisa kana paine shanduko mukushanda kweuropi mushure mekurapwa kwakati.

Ndinofanira kugadzirira sei ndisati ndaskena?

Kugadzirira fMRI scan kwakakosha zvikuru nekuti muchina unoshandisa magineti akasimba kwazvo, saka unofanira kungwarira zvakanyanya nezvekuchengetedzwa kwako.

Chiremba wako achakutsanangurira izvi, asi kazhinji unofanira kuteerera zvinhu izvi.

• Usanwe chero chinhu chine caffeine (kofi, tii, zvinwiwa zvisina kudhakwa) pazuva rekuongororwa, sezvo zvingakanganisa mhedzisiro yekuongororwa.
• Udza chiremba wako nezvemishonga yauri kutora. Iye achakuudza kana uchifanira kuinwa kana kusainwa usati waongororwa.
• Usapfeke kana kutakura chero chinhu chesimbi . Haisi simbi ine magineti chete, asiwo simbi isina magineti inogona kukanganisa kujeka kwescan.

Zvinhu zvaunofanira kuudza chiremba wako zvechokwadi

Ichi ndicho chinhu chinonyanya kukosha. Kana uine simbi kana michina yemagetsi mumuviri wako, unofanira kuzivisa chiremba wako nevashandi vari kuita scan nezvazvo usati waskena.

Uyewo, kana uine claustrophobia (kutya nzvimbo diki dzakavharika), udza chiremba wako pachine nguva. Kana zvichidikanwa, chiremba anogona kukupa mushonga mudiki wekudzikamisa pfungwa dzako.

Chii chinoitika panguva yekuskena?

Kuita scan iri nyore kwazvo.

Uchaitwa kuti urare pamubhedha, uye mushandi wepamubhedha achakutungamirira nokungwarira mumuchina mukuru, wakatenderera. Mudziyo wakakosha (head coil) uchaiswa pamusoro wako, sengowani. Izvi zvichabatsira kuita kuti mifananidzo yehuropi hwako ijeke. Uchapihwawo mahedhifoni kuti akubatsire kunzwa ruzha kubva kumuchina. Vashandi vachakwanisa kutaura newe uye kukupa mirairo kuburikidza nemahedhifoni aya.

Sezvandambotaura, muMRI yenguva dzose, unongoudzwa kuti ugare wakadzikama. Asi mufMRI, unokumbirwa kuita mabasa madiki panguva yekuskena.

Semuenzaniso, uchaudzwa kuti:

• Chinja minwe yako zvishoma.
• Taura chirevo chipfupi.
• Tarisa mufananidzo uri pachiratidziro.

Paunenge uchiita basa iri, muchina we fMRI unonyora nzvimbo dzehuropi hwako dziri kushanda. Unogona kuita basa iri nenzira mbiri.

1. Sisitimu yekuvhara: Muizvi, unoudzwa kuti uite chimwe chinhu kwemasekonzi mashoma, wobva wamirira kwemasekonzi mashoma wozochiita zvakare.

2. Sisitimu yezviitiko: Izvi zvinokutendera kuti uite mabasa akasiyana-siyana panguva imwe chete.

Dzimwe nguva unokumbirwa kuti usaite chinhu, ingogara ipapo wakavhara maziso ako kana kuti wakavhurika. Izvi zvinonzi "resting state scan". Inoyera mashandiro europi paunenge wakazorora.

Dzimwe nguva, mushonga unoderedza kupenya unonzi gadolinium unogona kuiswa mutsinga iri muruoko rwako kuti scan inyatsojeka.

Kuongororwa kwe fMRI yese kunowanzo tora awa imwe chete .

Ndezvipi zvakanakira uye zvakaipa zve scan?

Kufanana nechero bvunzo dzekurapa, fMRI ine zvayakanakira uye zvimwe zvinhu zvinofungwa nezvazvo.

Chii chakasiyana pakati pe fMRI ne EEG?

EEG (Electroencephalogram) inzira yekuyera mashandiro ehuropi. Asi pane musiyano mukuru pakati pezviviri izvi.

• fMRI inoratidza mashandiro ehuropi semufananidzo . Tinogona kuona chaizvo kuti ndeapi nzvimbo dzehuropi dziri kushanda.
• EEG inoratidza mashandiro ehuropi semafungu anotorwa papepa kana pachikirini.

Zvichitaurwa zviri nyore, nepo fMRI ichipindura mubvunzo wekuti "kupi?", EEG inonyanya kupindura mubvunzo wekuti "rini?", kureva kuti, kuchinja nekukurumidza kwemabasa.
