Kiʻi resonance ʻume mākeneka: he aha ia, he aha ia a pehea e hana ai

Anter

• No ke aha ia
• Pehea e hana ai
• Nā ʻano o MRI

Mākēneki resonance kiʻi (MRI), i ʻike ʻia me ke kiʻi nukelea kiʻi resonance (NMR), he hōʻike kiʻi hiki ke hōʻike i nā ʻōnaehana kūloko o nā lālā me ka wehewehe ʻana, he mea nui e kuhi i nā pilikia olakino like ʻole, e like me ka aneurysms, nā tumors, nā hoʻololi o nā hono a i ʻole nā ​​ʻeha ʻē aʻe i nā ʻōpū o loko.

I mea e hana ai i ka hoʻokolokolo ʻana, hoʻohana ʻia kahi mīkini nui, kahi e hana ai i nā kiʻi wehewehe kiʻekiʻe o nā mea kūloko ma o ka hoʻohana ʻana i ka māla magnet, ka mea e hoʻonāukiuki ai nā mole o ke kino, hopu ʻia e ka hāmeʻa a lawe ʻia i kahi kamepiula. Lōʻihi ka hōʻike ma kahi o 15 a 30 mau minuke a, maʻamau, ʻaʻohe pono o ka hoʻomākaukau, ʻoiai pono paha e hoʻohana i kahi ʻokoʻa, i kekahi mau hihia, ma o ka hoʻopili ʻana o ka lāʻau i loko o ke aa koko.

Mīkini MRI

Mākēneki resonance kiʻi o ka iwi poʻo

No ke aha ia

Hōʻike ʻia ke kiʻi resonance ʻume mākenēki i nā hihia aʻe:

• E ʻike i nā maʻi neurological, e like me ka Alzheimer, ka maʻi tumo o ka lolo, nā sclerosis he nui a i ʻole ka hahau ʻana, no ka laʻana;
• E nānā i ka hoʻohaunaele a i ʻole nā ​​maʻi i ka lolo, nā aʻalolo a i ʻole nā ​​ami.
• Nānā i nā hōʻeha musculoskeletal, e like me ka tendonitis, nā ʻeha ligament, nā cist, e like me kā Tarlov cyst a i ʻole nā ​​herniated discs, no ka laʻana;
• Hoʻomaopopo i nā lehulehu a i ʻole nā ​​tumors i loko o nā kino o ke kino;
• E nānā i nā loli i nā kīʻaha koko, e like me nā aneurysms a i ʻole nā ​​huʻa.

Pono e mālama i kekahi mau akahele ma mua o ka hana ʻana i kēia hoʻokolohua, no ka mea, ʻaʻole hiki ke loaʻa kekahi ʻano o nā mea hao e pili kokoke ana i ka māla ʻume mākenēki o ka hāmeʻa, e like me nā hairpins, nā aniani a i ʻole nā ​​kikoʻī lole, a pēlā e hōʻalo ai i nā pōʻino. No kēia kumu like, ʻaʻa ʻia kēia hōʻike no ka poʻe i loaʻa kekahi ʻano prostesis, pacemakers a i ʻole nā ​​pine metallic i hoʻokomo ʻia i loko o ke kino.

Ma waho aʻe o ka maikaʻi maikaʻi o nā kiʻi i hoʻokumu ʻia e ke kiʻi resonance ʻumeʻume, ʻo kahi pono ʻē aʻe ka hoʻohana ʻole ʻana o ka radiation ionizing e loaʻa nā hopena, ʻokoʻa i ka tomography i helu ʻia. E hoʻomaopopo he aha ia a no ka manawa e pono ai kahi scan CT.

Pehea e hana ai

ʻO ke kiʻi resonance ʻume mākenēki mau ma waena o 15 a 30 mau minuke, a hiki ke hala i 2 mau hola e pili ana i ka wahi e nānā ʻia. No kēia, pono e noho i loko o ka hāmeʻa e hoʻokuʻu i ka māla magnet, a ʻaʻole ʻeha ia, akā, he mea nui ʻaʻole e neʻe i kēia wā, ʻoiai hiki i kekahi neʻe ke hoʻololi i ka maikaʻi o ka hoʻokolokolo.

I ka poʻe hiki ʻole ke kū mālie, e like me nā keiki, ka poʻe me claustrophobia, dementia a i ʻole schizophrenia, no ka laʻana, pono paha e hana i ka hoʻāʻo me ka sedation e hoʻoulu ai i ka hiamoe, a i ʻole e maikaʻi ʻole ka hōʻike.

Hoʻohui ʻia, i kekahi mau hihia, pono paha e hoʻopili i kahi ʻokoʻa i ka aa o ka mea maʻi, e like me Gallium, ʻoiai he ala ia e hoʻonui ai i ka wehewehe ʻana o nā kiʻi, ʻo ka mea nui e ʻike i nā meaola a i ʻole nā ​​kīʻaha koko.

Nā ʻano o MRI

Pili nā ʻano o MRI i ka pūnaewele i hoʻopilikia ʻia, ʻo ka mea maʻamau e pili pū me:

• Nā kiʻi resonance ʻume mākenēki o ke pelvis, ʻōpū a i ʻole pahu. lawelawe ia e kuhikuhi i nā tumors a i ʻole nā ​​lehulehu i nā ʻāpana e like me ka ʻōpū, ʻōpū, ovaries, prostate, bladder, pancreas, a puʻuwai paha, e laʻa me;
• Kiʻi resonance ʻume mākenēki o ka iwi poʻo: kōkua i ka loiloi i nā lolo o ka lolo, ke kahe ʻana o ka naʻau, ka thrombosis cerebral, nā ʻōpū o ka lolo a me nā hoʻololi a i ʻole nā ​​maʻi ʻē aʻe i ka lolo a i ʻole kāna mau moku;
• Spine MRI: kōkua i ka hōʻoia ʻana i nā pilikia ma ka iwi kuamoʻo a me ka iwi kuamoʻo, e like me nā tumors, ka helu ʻana, hernias a i ʻole nā ​​ʻāpana iwi, ma hope o nā haki - E ʻike pehea e ʻike ai i ka arthrosis i ka iwi kuamoʻo, no ka laʻana;
• MRI o nā hono, e like me ka poʻohiwi, ke kuli a me nā kuʻekuʻe wāwae: lawelawe ia e loiloi i nā aʻa palupalu i loko o ka ami, e like me ka bursa, nā uaua a me nā ligament.

No laila ke kiʻi imaging magnetic me ka resonance kiʻi maikaʻi loa e nānā i nā ʻāpana palupalu o ke kino, akā naʻe, ʻaʻole hōʻike pinepine ʻia e nānā i nā leona i nā wahi ʻoʻoleʻa, e like me nā iwi, ʻo ia hoʻi, ma kēia mau hihia, nā hoʻokolohua e like me x-ray a i ʻole. kuhikuhi hou ʻia ka tomography., ʻo kahi laʻana.
