Wetin rili na MRI (Magnetic Resonance Imaging)?

Fɔ tɔk am simpul wan, MRI na tɛst we nɔ de mek wi fil pen ɛn we de mek wi ebul fɔ si di tin dɛn we de insay wi bɔdi lɛk di ɔgan dɛn ɛn di tisu dɛn klia wan . I de yuz big magnet, redio wev, ɛn kɔmpyuta fɔ mek ditayli pikchɔ dɛn bɔt di insay pat na wi bɔdi. Di tin we impɔtant pas ɔl na dat i nɔ de yuz ɛkstrem rayt, ɔ raytin.

Bɔku tɛm, if pɔsin nid fɔ skan am ɔltɛm, mɔ fɔ say dɛn lɛk in bren, dɔktɔ dɛn kin pik dis MRI. Di rizin fɔ dis na bikɔs bikɔs redyushɔn nɔ de, i nɔ de du bɔku bad tin if dɛn du am bɔku tɛm.

Wetin na ‘Open MRI’?

Naw, tu kayn MRI mashin dɛn de. Wan na di kayn ‘Open MRI’. Insay dis, yu de ledɔm na bed, ɛn tu flat magnet dɛn de ɔp ɛn dɔŋ yu. Dis kin mek big ples de na ɔl tu di say dɛn. Sɔm pipul dɛn kin fil lɛk se dɛn nɔ gɛt wanwɔd we dɛn go insay di ɔda kayn MRI mashin. Fɔ dɛn, di ‘Open MRI’ rili fayn bikɔs i nɔ kin kramp.
