ʻO ka maʻi sclerosis he maʻi olakino maʻamau kahi e pōʻino ai ka myelin, ka uhi e pale ai i nā pūnaʻi aʻalolo i loko o ka lolo a me ke kuamoʻo o ke kanaka. ʻIke ʻia ka pōʻino ma kahi MRI scan (MRI high pressure medium injector). Pehea ka hana MRI no MS?
Hoʻohana ʻia ka injector kiʻekiʻe kiʻekiʻe MRI e hoʻokomo i ke ʻano like ʻole i ka nānā ʻana i ka lāʻau lapaʻau e hoʻomaikaʻi i ka ʻokoʻa kiʻi a hoʻomaʻamaʻa i ka maʻi maʻi. ʻO ka MRI scan kahi hoʻāʻo kiʻi e hoʻohana ana i kahi māla magnetic a me nā hawewe lekiō e hana i kahi kiʻi ma ke ana ʻana i ka wai i loko o nā kiko. ʻAʻole pili i ka hoʻolaha ʻana i ka radiation. He ala hana kiʻi kūpono ia e hiki ai i nā kauka ke hoʻohana no ka ʻike ʻana iā MS a me ka nānā ʻana i kona holomua. Pono ka MRI no ka mea, ʻo ka myelin, ka mea a MS e luku ai, he ʻiʻo momona. Ua like ka momona me ka aila no ka mea e pale ana i ka wai. E like me ke ana ʻana o ka MRI i ka wai, e hōʻike ʻia nā wahi o ka myelin i pōʻino. Ma ke kiʻi kiʻi, hiki ke ʻike ʻia nā wahi i hōʻino ʻia a i ʻole keʻokeʻo a ʻeleʻele paha, ma muli o ke ʻano o ka MRI scanner a i ʻole ke kaʻina. ʻO nā laʻana o nā ʻano kaʻina hana MRI a nā kauka e hoʻohana ai no ka hoʻomaʻamaʻa ʻana i ka MS: T1-kaumaha: Na ka radiologist e hoʻokomo i ke kanaka me kahi mea i kapa ʻia ʻo gadolinium. ʻO ka mea maʻamau, ʻoi aku ka nui o nā ʻāpana o ka gadolinium e hele i kekahi mau wahi o ka lolo. Eia naʻe, inā loaʻa i ke kanaka ka pōʻino i loko o ka lolo, e hōʻike ana nā ʻāpana i ka wahi i poino. ʻO ka mākaʻikaʻi T1-kaumaha ka mea e ʻike ʻia ai ka pōʻeleʻele i hiki i ke kauka ke ʻike maʻalahi iā lākou. Nā mākaʻikaʻi T2-kaumaha: Ma kahi mākaʻikaʻi T2-kaumaha, e lawelawe ka mea radiologist i nā pulu like ʻole ma o ka mīkini MRI. He ʻokoʻa ka waihoʻoluʻu o nā ʻeha kahiko i nā ʻeha hou. ʻAʻole like me nā kiʻi scan paona-T1, ʻike ʻia nā ʻeha ma nā kiʻi paona T2. Fluid-attenuated inversion recovery (FLAIR): Hoʻohana nā kiʻi FLAIR i kahi kaʻina like ʻole o nā pulse ma mua o ke kiʻi T1 a me T2. Paʻa loa kēia mau kiʻi i nā ʻeha o ka lolo i hana pinepine ʻia e MS. ʻO ke kiʻi kiʻi spinal cord: ʻO ka hoʻohana ʻana i kahi MRI e hōʻike i ke kuamoʻo hiki ke kōkua i ke kauka e ʻike i nā ʻeha e hiki mai ana ma ʻaneʻi a me ka lolo, he mea nui i ka hana ʻana i kahi hōʻailona MS. Hiki paha i kekahi poʻe ke loaʻa i ka maʻi maʻi i ka gadolinium i hoʻohana ʻia e T1-weighted scans. Hiki i ka Gadolinium ke hoʻonui i ka hopena o ka pōʻino o ka puʻupaʻa i nā poʻe i loaʻa i kahi emi o ka hana kīkī.
