Ibizamini bya radiologiya kuri sclerose nyinshi

Indwara ya sklerarose ni indwara idakira aho yangirika myelin, igifuniko kirinda ingirabuzimafatizo mu bwonko bw'umuntu no mu ruti rw'umugongo. Ibyangiritse bigaragara kuri scan ya MRI (MRI yihuta yo gutera inshinge). Nigute MRI ya MS ikora?

Injira ya MRI yumuvuduko mwinshi ikoreshwa mugutera inshusho itandukanye mugusuzuma amashusho yubuvuzi kugirango tunonosore itandukaniro ryishusho kandi byorohereze abarwayi. Isuzuma rya MRI ni ikizamini cyerekana amashusho ikoresha umurima wa rukuruzi hamwe numurongo wa radio kugirango ukore ishusho mugupima amazi arimo. Ntabwo ikubiyemo imirasire. Nuburyo bwiza bwo gufata amashusho abaganga bashobora gukoresha mugupima MS no gukurikirana iterambere ryayo. MRI ni ingirakamaro kuko myelin, ibintu MS isenya, bigizwe nuduce twinshi. Ibinure bimeze nkamavuta kuko yanga amazi. Nka MRI ipima ibirimo amazi, uduce twa myelin yangiritse tuzagaragara neza. Kuri scan yerekana amashusho, ahantu harangiritse hashobora kugaragara haba umweru cyangwa umwijima, bitewe n'ubwoko bwa scaneri ya MRI cyangwa ikurikiranye. Ingero zubwoko bwa MRI zikurikirana abaganga bakoresha mugupima MS harimo: T1 ifite uburemere: Radiologue azatera umuntu ibikoresho byitwa gadolinium. Mubisanzwe, ibice bya gadolinium nini cyane kuburyo bitanyura mubice bimwe byubwonko. Ariko, niba umuntu afite ibyangiritse mubwonko, ibice bizagaragaza aho byangiritse. Gusikana uburemere bwa T1 bizatera ibikomere kugaragara ko ari umwijima kugirango umuganga abimenye byoroshye. Gusuzuma uburemere bwa T2: Muri scan ya T2 ifite uburemere, radiologue azatanga impiswi zitandukanye akoresheje imashini ya MRI. Ibisebe bishaje bizagaragara ibara ritandukanye kubishya. Bitandukanye na T1 ifite uburemere bwa scan, ibisebe bigaragara ko byoroshye kumashusho ya T2 afite uburemere. Fluid-attenuated inversion recovery (FLAIR): Amashusho ya FLAIR akoresha urukurikirane rutandukanye rwa pulses kuruta amashusho ya T1 na T2. Aya mashusho yunvikana cyane kubikomere byubwonko MS isanzwe itera. Kwerekana uruti rw'umugongo: Gukoresha MRI kugirango werekane uruti rw'umugongo birashobora gufasha umuganga kumenya ibikomere bibera hano ndetse no mu bwonko, bifite akamaro mugupima MS. Abantu bamwe bashobora guhura nibibazo bya allergique kuri gadolinium scan ya T1 ifite uburemere bukoresha. Gadolinium irashobora kandi kongera ibyago byo kwangirika kwimpyiko kubantu basanzwe bafite igabanuka ryimikorere yimpyiko.
