Multiple sclerosis ndi matenda aakulu omwe amachititsa kuwonongeka kwa myelin, chophimba chomwe chimateteza maselo a mitsempha mu ubongo wa munthu ndi msana. Kuwonongeka kumawonekera pa MRI scan (MRI high pressure medium jekeseni). Kodi MRI ya MS imagwira ntchito bwanji?
MRI high pressure injector imagwiritsidwa ntchito kubaya sing'anga pazithunzi zachipatala kuti zitheke kusiyanitsa zithunzi ndikuthandizira kuzindikira kwa odwala. Kujambula kwa MRI ndi kuyesa kojambula komwe kumagwiritsa ntchito mphamvu ya maginito ndi mafunde a wailesi kuti apange chithunzi poyesa madzi omwe ali mu minofu. Simaphatikizapo kukhudzana ndi ma radiation. Ndi njira yojambulira yomwe madotolo angagwiritse ntchito poyezera MS ndikuwunika momwe ikuyendera. MRI ndiyothandiza chifukwa myelin, chinthu chomwe MS chimawononga, chimakhala ndi minofu yamafuta. Mafuta ali ngati mafuta chifukwa amathamangitsa madzi. Monga MRI imayeza madzi, madera a myelin owonongeka adzawonekera bwino. Pojambula zithunzi, malo owonongeka amatha kuwoneka oyera kapena akuda, malingana ndi mtundu wa scanner ya MRI kapena ndondomeko. Zitsanzo za mitundu yotsatizana ya MRI yomwe madokotala amagwiritsa ntchito pozindikira MS ndi izi: Zolemera T1: Katswiri wa radiologist amabaya munthu ndi zinthu zotchedwa gadolinium. Nthawi zambiri tinthu tating'onoting'ono ta gadolinium timakhala tokulirapo kwambiri moti sitingathe kudutsa mbali zina za ubongo. Komabe, ngati munthu wawonongeka mu ubongo, tinthu tating'onoting'ono timawonetsa malo owonongeka. Kujambula kolemera kwa T1 kumapangitsa kuti zotupa ziwoneke zakuda kuti adotolo azitha kuzizindikira mosavuta. Kujambula kolemera kwa T2: Pakujambula kolemera kwa T2, katswiri wa radiologist adzapereka mapiko osiyanasiyana kudzera mu makina a MRI. Zotupa zakale zidzawoneka zamtundu wosiyana ndi zatsopano. Mosiyana ndi zithunzi zojambulidwa zolemera za T1, zotupa zimawoneka zopepuka pazithunzi zolemedwa ndi T2. Fluid-attenuated inversion recovery (FLAIR): Zithunzi za FLAIR zimagwiritsa ntchito machitidwe osiyanasiyana amtundu kusiyana ndi kujambula kwa T1 ndi T2. Zithunzizi zimakhudzidwa kwambiri ndi zotupa za muubongo zomwe MS nthawi zambiri zimayambitsa. Kujambula kwa msana: Kugwiritsa ntchito MRI kusonyeza msana kungathandize dokotala kuzindikira zilonda zomwe zimachitika pano komanso mu ubongo, zomwe ndizofunikira popanga matenda a MS. Anthu ena akhoza kukhala pachiwopsezo chotengera gadolinium yomwe ma scans a T1-weighted amagwiritsa ntchito. Gadolinium imathanso kuonjezera chiopsezo cha kuwonongeka kwa impso mwa anthu omwe ali ndi kuchepa kwa impso.
