Mākōkō resonance angiography

ʻO ka angiography resonance ʻume mākenēki (MRA) kahi hōʻike MRI o nā kīʻaha koko. ʻAʻole like me ka angiography kuʻuna e pili ana i ke kau ʻana i kahi paipu (catheter) i loko o ke kino, noninvasive ʻo MRA.

Nonoi ʻia ʻoe e ʻaʻahu i ke kapa komo i ka haukapila. Hiki iā ʻoe ke komo i ka lole me ka ʻole o nā mea hoʻopaʻa hao (e like me ka sweatpants a me kahi pālule). Hiki i kekahi ʻano metala ke kumu i nā kiʻi blurry.

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

Koi ʻia kekahi mau hoʻāʻo i kahi kala kūikawā (ʻokoʻa). ʻO ka pinepine, hāʻawi ʻia ka kala ma mua o ka hoʻāʻo ma o kahi aa (IV) i kou lima a i ʻole ka lima. Kōkua ka wai kala i ka radiologist e ʻike maopopo i kekahi mau wahi.

I ka wā o ka MRI, e nānā ka mea nāna e hoʻohana i ka mīkini iā ​​ʻoe mai kahi lumi ʻē aʻe. Lōʻihi paha ka hola ma ka hoʻāʻo.

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). Hāʻawi ʻia ʻoe i ka lāʻau e kōkua iā ʻoe e hiamoe a hoʻoliʻiliʻi liʻiliʻi. E ʻōlelo paha kāu mea hāʻawi i kahi MRI "wehe". I ka MRI hāmama, ʻaʻole kokoke ka mīkini i ke kino.

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

• Nā kiʻi anurysm lolo
• Pāpā puʻuwai puʻuwai
• ʻO ka defibrillator puʻuwai a i ʻole pacemaker
• Hoʻokomo nā pepeiao loko (cochlear)
• Ke awa insulina a chemotherapy paha
• Intrauterine hāmeʻa (IUD)
• ʻO ka maʻi kīkī a i ʻole ka dialysis (ʻaʻole hiki iā ʻoe ke loaʻa ka hoʻohālikelike)
• Neurostimulator
• Ua hoʻonoho ʻia i nā hono kuʻi
• Stent Vascular
• 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)

Ma muli o ka MRI i nā mākēneki ikaika, ʻaʻole ʻae ʻia nā mea metala i loko o ka lumi me ka scanner MRI. Hōʻalo i ka lawe ʻana i nā mea e like me:

• Nā ʻeke ʻeke, nā peni, a me nā aniani aniani
• Nā wati, nā kāleka hōʻaiʻē, nā mea hoʻonaninani, a me nā mea kōkua pepeiao
• ʻO nā lauoho, nā zipa metala, nā pine, a me nā mea like
• Hiki ke hoʻoneʻe ʻia nā kahua niho niho

ʻAʻole loaʻa kahi ʻeha i kahi hōʻike MRA. Inā loaʻa iā ʻoe kahi pilikia e moe ana a makaʻu loa paha, hāʻawi ʻia ʻoe i lāʻau lapaʻau (sedative) e hoʻomaha ai iā ʻoe. Hiki ke hoʻoneʻe i ka neʻe nui ʻana 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. Hoʻopuka ka mīkini i nā kani kani kani a kani i ke kani ʻana. Hiki iā ʻoe ke komo i nā kui pepeiao e kōkua ai e hoʻēmi 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 mīkini paʻi nā kīwī a me nā pepeiao pepeiao kūikawā i hiki iā ʻoe ke hoʻohana e kōkua i ka hala ʻana o ka manawa.

ʻAʻohe manawa hoʻōla, ke hāʻawi ʻole ʻia ʻoe i lāʻau e hoʻomaha ai.

Hoʻohana ʻia ka MRA e nānā i nā kīʻaha koko i nā ʻāpana āpau o ke kino. E hana ʻia paha ka hoʻāʻo no ke poʻo, ka puʻuwai, ka ʻōpū, nā māmā, nā puʻupaʻa, a me nā wāwae.

Hiki ke hoʻohana ʻia e ʻike a loiloi paha i nā kūlana e like me:

• Aneurysm arterial (kahi ākea ākea a paluna paha o kahi ʻāpana o ke aʻa ma muli o ka nāwaliwali i ka paia o ka ipu koko)
• Hoʻohālikelike aortic
• Dissection ʻaʻano
• Hahau
• Maʻi maʻi aʻa Carotid
• ʻO Atherosclerosis o nā lima a me nā wāwae
• ʻO ka maʻi puʻuwai, me ka maʻi puʻuwai congenital
• ʻO ka ischemia artery Mesenteric
• Renal stenosis (hōʻemi o nā kīʻaha koko i nā puʻupaʻa)

ʻO kahi hopena maʻamau ʻaʻole hōʻike nā kīʻaha koko i nā hōʻailona o ke kaha ʻana a paʻa paha.

Hōʻike kahi hopena maikaʻi ʻole i kahi pilikia me hoʻokahi a ʻoi paha o nā kīʻaha koko. Kuhi paha kēia:

• Atherosclerosis
• Trauma
• Maʻi maʻi hānau
• ʻO ke kūlana vascular ʻē aʻe

Palekana ʻo MRA i kahi palekana. Hoʻohana ʻole ia 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 hoʻohālikelike i hoʻohana ʻia i loko o 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 ʻōpū e koi ana i ka dialysis. Inā loaʻa iā ʻoe nā pilikia o ka hakuʻala, e ʻoluʻolu e haʻi i kāu mea hoʻolako ma mua o ka hoʻāʻo.

Hiki i nā māla ikaika ikaika i hana ʻia i ka MRI ke hana i nā puʻuwai puʻuwai a me nā mea ʻē aʻe i hana ʻole pū kekahi. Hiki iā lākou ke hoʻoneʻe i kahi ʻāpana o ka metala i loko o kou kino.
