Poʻo MRI

ʻO kahi poʻo MRI (magnetic resonance imaging) kahi hōʻike kiʻi e hoʻohana i nā mākēneka mana a me nā nalu lekiō e hana i nā kiʻi o ka lolo a me nā aʻa a puni.

ʻAʻole ia e hoʻohana i ka radiation.

Hana ʻia ʻo Head MRI i ka haukapila a i ʻole kikowaena radiology.

Moe ʻoe i ka papaʻaiki liʻiliʻi, e pāheʻe ai i kahi scanner e like me ke ʻano o ke ana.

Pono kekahi mau hoʻokolohua MRI i kahi kala kūikawā, i kapa ʻia he mea hoʻohālikelike. Hāʻawi pinepine ʻia ke kala i ka wā o ka hoʻāʻo ma o ke aa (IV) i kou lima a i ʻole ka forearm. Kōkua ka wai kala i ka radiologist e ʻike maopopo i kekahi mau wahi.

I ka wā o ka MRI, nānā ka mea nāna ʻoe e hoʻohana i ka mīkini iā ​​ʻoe mai kahi lumi ʻē aʻe. ʻO ka hoʻāʻo pinepine ka lōʻihi o 30 a 60 mau minuke, akā lōʻihi paha ka lōʻihi.

E noi ʻia ʻoe ʻaʻole e ʻai a inu paha i kekahi mea no 4 a 6 mau hola ma mua o ka scanner.

E haʻi i kāu mea mālama ola inā makaʻu ʻoe i nā wahi kokoke (loaʻa claustrophobia). Loaʻa paha iā ʻoe ka lāʻau e kōkua ai iā ʻoe e hiamoe a hoʻoliʻiliʻi liʻiliʻi. A i ʻole e hōʻike paha kāu mea hāʻawi i kahi MRI "wehe", kahi i kokoke ʻole ai ka mīkini i ke kino.

Hiki iā ʻoe ke noi e ʻaʻahu i kahi kapa komo no ka haukapila a lole paha me ka ʻole o nā kaula hao (e like me ka sweatpants a me kahi pālule). Hiki i kekahi ʻano metala ke kumu i nā kiʻi blurry.

Ma mua o ka hoʻāʻo, e haʻi i kāu mea hāʻawi inā loaʻa iā ʻoe:

• Nā kiʻi anurysm lolo
• Kahi puʻuwai puʻuwai hana
• ʻO ka defibrillator puʻuwai a i ʻole pacemaker
• Hoʻokomo nā pepeiao loko (cochlear)
• ʻO ka maʻi kīkī a i ʻole ma ka dialysis (ʻaʻole hiki iā ʻoe ke loaʻa ka hoʻohālikelike)
• I hoʻonoho ʻia i hui pū ʻia
• Kahi kīʻaha koko
• Hana ʻia me ka metala i ka wā i hala (pono ʻoe i nā hoʻokolohua e nānā no nā ʻāpana metala i kou mau maka)

Loaʻa i ka MRI nā mākēneki ikaika. ʻAʻole ʻae ʻia nā mea metala i loko o ka lumi me ka scanner MRI. Pākuʻi ʻia kēia:

• Nā peni, nā ʻeke ʻeke, a me nā aniani aniani
• Nā mea e like me nā mea nani, nā uaki, nā kāleka hōʻaiʻē, a me nā mea kōkua lohe
• Nā pine, nā pale lauoho, nā ziper metala, a me nā mea hao like
• Hana niho hiki ke hemo

Inā ʻoe e makemake i ka kala, e ʻike ʻoe i ka kui kui kuʻi i kou lima ke hoʻokomo ʻia ke kala i ka aa koko.

ʻAʻohe ʻeha kahi hōʻike MRI. Inā pilikia ʻoe i ka moe ʻana a i ʻole makaʻu loa, hāʻawi ʻia ʻoe i lāʻau e hoʻomaha ai. Hiki i ka neʻe nui loa ke hoʻomālamalama i nā kiʻi a hana i nā hewa.

He paʻakikī a anuanu paha ka papaʻaina, akā hiki iā ʻoe ke noi no kahi kapa a uluna paha. Hana ka mīkini i ka leo nui a kani i ka kani ke kani ʻia. Hiki iā ʻoe ke noi i nā plug pepeiao e kōkua i ka hoʻohaʻahaʻa ʻana i ka walaʻau.

ʻO kahi intercom i loko o ka lumi e ʻae iā ʻoe e kamaʻilio me kekahi i kēlā me kēia manawa. Loaʻa i kekahi mau MRI nā kīwī a me nā pepeiao pepeiao kūikawā i hiki ke kōkua iā ʻoe e hoʻolilo i ka manawa a pale paha i ka leo o ka scanner.

ʻAʻohe manawa hoʻōla, ke hāʻawi ʻole ʻia ʻoe i lāʻau e hoʻomaha ai. Ma hope o ka scan MRI, hiki iā ʻoe ke hoʻi i kāu papaʻai maʻamau, hana, a me nā lāʻau.

Hāʻawi kahi MRI i nā kiʻi kikoʻī o ka lolo a me nā aʻa nerve.

Hiki ke hoʻohana ʻia kahi MRI lolo e hōʻoia a nānā i nā maʻi a me nā maʻi e hoʻopili i ka lolo, e like me:

• Hewa hānau
• Kahe ʻana (kahe kahe a kahe paha o ka subarachnoid i kaʻiʻo o ka lolo iā ia iho)
• ʻO Aneurysms
• ʻO ka maʻi, e like me ka abscess o ka lolo
• Tumors (cancerous a me noncancerous)
• Nā maʻi Hormonal (e like me ka acromegaly, galactorrhea, a me Cushing syndrome)
• Sclerosis lehulehu
• Hahau

Hiki i kahi scan MRI o ke poʻo ke hoʻoholo i ke kumu o:

• Nāwaliwali o ka mākala a me ka helu a me ke kani ʻana
• Hoʻololi i ka noʻonoʻo a i ʻole ka lawena
• Lohe hoʻolohe
• Headaches ke loaʻa kekahi mau ʻōuli ʻē aʻe a i ʻole nā ​​hōʻailona
• Pilikia ʻōlelo
• Nā pilikia ʻike
• Dementia

Hiki ke hana ʻia kekahi ʻano MRI kūikawā i kapa ʻia he angiography resonance magnet (MRA) e nānā i nā kīʻaha koko i ka lolo.

Nā hopena kūpono ʻole ma muli o:

• Nā kīʻaha koko kūpono ʻole i ka lolo (malterations o ke poʻo)
• Tumor o ke aʻalolo e hoʻopili i ka pepeiao i ka lolo (acoustic neuroma)
• Kahe i ka lolo
• Maʻi maʻi lolo
• ʻŌhū o ka lolo
• ʻOrspala lolo
• Poino i ka lolo mai kahi ʻeha
• ʻO ka hōʻiliʻili wai a puni ka lolo (hydrocephalus)
• ʻO ka maʻi o nā iwi iwi poʻo (osteomyelitis)
• Ka nalowale o kaʻiʻo lolo
• Sclerosis lehulehu
• Ka hahau a i ʻole ka hoʻouka ischemic kuewa (TIA)
• Nā pilikia kūkulu i ka lolo

ʻAʻole hoʻohana ʻo MRI i ka pāhawewe. I kēia lā, ʻaʻole i hōʻike ʻia nā hopena ʻē aʻe mai nā māla magnet a me nā nalu lekiō.

ʻO ka ʻano maʻamau o ka ʻokoʻa (kala) i hoʻohana ʻia ʻo gadolinium. Palekana loa ia. ʻAʻole hiki ke hana i nā hopena āpau i ka lāʻau. Eia nō naʻe, hiki i ka gadolinium ke lilo i mea hōʻino i ka poʻe me nā pilikia puʻupaʻa e noho ana ma ka dialysis. Inā loaʻa iā ʻoe nā pilikia o ka hakuʻala, e haʻi i kāu mea hoʻolako ma mua o ka hoʻāʻo.

Hiki i nā māla magnetika ikaika i hana ʻia i ka MRI ke hana i nā pacemaker puʻuwai a me nā implants ʻē aʻe ʻaʻole e holo pū kekahi. Hiki iā ia ke hoʻoneʻe i kahi ʻāpana o ka hao i loko o kou kino.

Palekana ʻo MRI i ka wā hāpai. I nā manawa he nui ʻoi aku ka maʻalahi o ka MRI ma mua o ka scan CT i nā pilikia i ka lolo e like me nā poʻe liʻiliʻi. ʻOi aku ka maikaʻi o ka CT ma ka ʻimi ʻana i nā wahi liʻiliʻi o ke kahe ʻana o ke kahe.

ʻO nā hoʻāʻo e hiki ke hana ma kahi o kahi MRI o ke poʻo e komo pū:

• Poʻomanaʻo CT poʻo
• Positron emission tomography (PET) scan o ka lolo

Hiki ke koho ʻia kahi scan CT ma nā hihia aʻe, ʻoiai ʻoi aku ka wikiwiki a loaʻa maʻamau i ka lumi pilikia.

• Huʻi koʻikoʻi o ke poʻo a me ka maka
• Kahe i ka lolo (ma waena o 24 a 48 mau hola mua)
• Nā ʻōuli o ke kīkēkē
• Nā maʻi iwi iwi a me nā maʻi e pili ana i nā iwi o ka pepeiao
