Multiple sclerosis chirwere chisingaperi chine kukuvara kwemyelin, chifukidziro chinodzivirira masero etsinga muuropi hwemunhu uye musana. Kukuvadza kunoonekwa paMRI scan (MRI high pressure medium injector). MRI yeMS inoshanda sei?
MRI high pressure injector inoshandiswa kubaya musiyano wepakati mukurapa imaging scanning kuti ivandudze kusiyana kwemifananidzo uye kufambisa kuongororwa kwemurwere. MRI scan bvunzo yekufungidzira inoshandisa magineti nemasaisai eredhiyo kugadzira mufananidzo nekuyera zviri mukati memvura mumatishu. Izvo hazvisanganisi kuratidzwa kwemwaranzi. Iyo inzira inoshanda yekufungidzira iyo vanachiremba vanogona kushandisa pakuongorora MS uye kutarisa mafambiro ayo. MRI inobatsira nekuti myelin, chinhu chinoparadzwa neMS, chine mafuta. Mafuta akafanana neoiri pakuti anodzinga mvura. Sezvo MRI inoyera zviri mukati memvura, nzvimbo dzemyelin dzakakuvadzwa dzicharatidza zvakajeka. Pama imaging scan, nzvimbo dzakakuvadzwa dzinogona kuoneka dzakachena kana kusviba, zvichienderana nerudzi rweMRI scanner kana kutevedzana. Mienzaniso yeMRI sequence types iyo vanachiremba vanoshandisa kuongorora MS inosanganisira: T1-inorema: The radiologist ichabaya munhu chinhu chinonzi gadolinium. Kazhinji, zvimedu zvegadolinium zvakakura zvakanyanya kuti zvipfuure nepakati pedzimwe nzvimbo dzehuropi. Zvisinei, kana munhu akakuvadzwa muuropi, zvimedu zvicharatidza nzvimbo yakakuvadzwa. A T1-weighted scan ichaita kuti maronda aratidzike akasviba kuti chiremba anogona kuaziva zviri nyore. T2-yakayereswa scans: MuT2-inorema scan, radiologist ichapa pulses dzakasiyana kuburikidza nemushini weMRI. Maronda ekare achaonekwa ruvara rwakasiyana kune zvitsva zvitsva. Kusiyana neT1-yakaremerwa scanning mifananidzo, maronda anooneka akareruka paT2-inorema mifananidzo. Fluid-attenuated inversion recovery (FLAIR): FLAIR mifananidzo inoshandisa kutevedzana kwakasiyana kwemapulses kupfuura T1 uye T2 imaging. Iyi mifananidzo inobata zvakanyanya kumaronda ehuropi ayo MS inowanzokonzera. Spinal cord imaging: Kushandisa MRI kuratidza musana kunogona kubatsira chiremba kuona maronda anoitika pano uyewo muuropi, izvo zvinokosha pakuita MS kuongororwa. Vamwe vanhu vanogona kunge vari panjodzi yekusawirirana negadolinium inoshandiswa neT1-weighted scans. Gadolinium inogonawo kuwedzera njodzi yekukuvadzwa kweitsvo muvanhu vanotova nekudzikira kweitsvo basa.
