Hoʻohana ʻo CT a me MRI i nā ʻano hana like ʻole e hōʻike i nā mea like ʻole - ʻaʻole pono kekahi e "ʻoi aku ka maikaʻi" ma mua o kekahi.
Hiki ke ʻike maka ʻia kekahi mau ʻeha a i ʻole nā kūlana. Pono kekahi i ka ʻike hohonu.
Inā kānalua kāu mea mālama ola i kahi kūlana e like me ke kahe koko o loko, kahi puʻupuʻu, a i ʻole ka hōʻino ʻana o nā ʻiʻo, hiki iā lākou ke kauoha i kahi CT scan a i ʻole MRI.
ʻO ke koho ʻana inā e hoʻohana i ka CT scan a i ʻole MRI aia i kāu mea mālama ola, ma muli o ka mea a lākou e manaʻo ai e loaʻa.
Pehea e hana ai ʻo CT a me MRI? ʻO wai ka mea maikaʻi loa no ke aha? E nānā pono kākou.
Hana ka CT scan, pōkole no ka computed tomography scan, ma ke ʻano he mīkini X-ray 3D. Hoʻohana ka CT scanner i kahi X-ray e hele ana ma waena o ka mea maʻi i kahi mea ʻike i ka wā e hoʻohuli ana a puni ka mea maʻi. Hopu ia i nā kiʻi he nui, a laila e hoʻākoakoa ai kahi kamepiula e hana i kahi kiʻi 3D o ka mea maʻi. Hiki ke hoʻoponopono ʻia kēia mau kiʻi ma nā ʻano like ʻole e loaʻa ai nā hiʻohiʻona kūloko o ke kino.
Hiki i kahi X-ray kuʻuna ke hāʻawi i kāu mea lawelawe i hoʻokahi nānā i ka wahi i kiʻi ʻia. He kiʻi paʻa ia.
Akā hiki iā ʻoe ke nānā i nā kiʻi CT e kiʻi i kahi ʻike maka manu o ka wahi i kiʻi ʻia. A i ʻole e milo a puni e nānā mai mua a i hope a i ʻole ʻaoʻao a ʻaoʻao. Hiki iā ʻoe ke nānā i ka papa waho loa o ka wahi. A i ʻole e hoʻokokoke hohonu i loko o ka ʻāpana o ke kino i kiʻi ʻia.
CT Scan: Pehea ke ʻano?
Pono ka loaʻa ʻana o kahi CT scan he hana wikiwiki a ʻeha ʻole. Moe ʻoe ma luna o kahi papa e neʻe mālie ana ma o ka mīkini nānā apo. Ma muli o nā koi a kāu mea mālama ola, pono paha ʻoe i nā dyes contrast intravenous. ʻAʻole i emi iho ma mua o hoʻokahi minute ka lōʻihi o kēlā me kēia scan.
ʻO ke kiʻi CT: No ke aha ia?
Ma muli o ka hoʻohana ʻana o nā mīkini scan CT i nā kukuna X, hiki iā lākou ke hōʻike i nā mea like me nā kukuna X, akā me ka pololei ʻoi aku. He ʻike pālahalaha ka kukuna X o kahi wahi kiʻi, ʻoiai hiki i ka CT ke hāʻawi i kahi kiʻi piha a hohonu.
Hoʻohana ʻia nā scan CT e nānā i nā mea e like me: Nā iwi, nā pōhaku, ke koko, nā kino, nā māmā, nā pae o ke kanesa, nā pilikia ʻōpū.
Hiki ke hoʻohana ʻia nā scan CT e nānā i nā mea i ʻike maikaʻi ʻole ʻia e MRI, e like me nā māmā, ke koko, a me nā ʻōpū.
CT scan: Nā pilikia kūpono
ʻO ka hopohopo nui a kekahi poʻe e pili ana i nā CT scans (a me nā X-ray no ia mea) ʻo ia ka hiki ke hōʻike ʻia ka radiation.
Ua manaʻo kekahi poʻe loea e hiki i ka radiation ionizing i hoʻopuka ʻia e nā scan CT ke hoʻonui iki i ka pilikia o ka maʻi kanesa i kekahi poʻe. Akā, ua hoʻopaʻapaʻa ʻia nā pilikia pololei. Ua ʻōlelo ka Food and Drug Administration ma muli o ka ʻike ʻepekema o kēia manawa, ʻaʻole maopopo ka pilikia o ka maʻi kanesa mai ka radiation CT.
Eia nō naʻe, ma muli o nā pilikia o ka radiation CT, ʻaʻole kūpono nā wahine hāpai no nā scan CT ke ʻole pono.
I kekahi manawa, hoʻoholo paha nā mea lawelawe mālama ola e hoʻohana i ka MRI ma kahi o CT e hōʻemi i ka pilikia o ka hōʻike ʻana i ka radiation. He ʻoiaʻiʻo loa kēia no ka poʻe me nā maʻi olakino e pono ai nā pōʻai he nui o ke kiʻi ʻana i kahi manawa lōʻihi.
MRI
ʻO MRI ke kū nei no ke kiʻi resonance magnetic. I ka pōkole, hoʻohana ʻo MRI i nā magnet a me nā nalu lekiō e hana i nā kiʻi i loko o kou kino.
ʻO ke ʻano kikoʻī o kāna hana e pili ana i kahi haʻawina physics lōʻihi. Akā i ka pōkole, ua like ia me kēia: Loaʻa i ko mākou kino ka nui o ka wai, ʻo ia hoʻi ʻo H20. ʻO ka H ma H20 ke kū nei no ka hydrogen. Loaʻa i ka hydrogen nā protons - nā ʻāpana i hoʻopiʻi maikaʻi ʻia. ʻO ka maʻamau, milo kēia mau protons i nā ʻaoʻao like ʻole. Akā i ka wā e hālāwai ai lākou me kahi magnet, e like me ka mīkini MRI, huki ʻia kēia mau protons i ka magnet a hoʻomaka e laina.
MRIPehea ke ʻano?
He mīkini tubular ka MRI. ʻO ka maʻamau o ka MRI scan maʻamau he 30 a 50 mau minuke, a pono ʻoe e noho mālie i ka wā o ke kaʻina hana. Hiki ke walaʻau nui ka mīkini, a hiki i kekahi poʻe ke pōmaikaʻi mai ke komo ʻana i nā earplugs a i ʻole ka hoʻohana ʻana i nā headphone e hoʻolohe i ke mele i ka wā o ka scan. Ma muli o nā pono o kāu mea lawelawe, hiki iā lākou ke hoʻohana i nā dyes contrast intravenous.
MRI: No ke aha ia?
He maikaʻi loa ka MRI i ka hoʻokaʻawale ʻana ma waena o nā ʻiʻo. No ka laʻana, hiki i nā mea lawelawe ke hoʻohana i ka CT kino holoʻokoʻa e ʻimi i nā puʻupuʻu. A laila, hana ʻia kahi MRI e hoʻomaopopo maikaʻi i nā puʻupuʻu i loaʻa ma ka CT.
Hiki i kāu mea lawelawe ke hoʻohana i ka MRI e nānā i ka hōʻino ʻana o nā hono a me nā hōʻino aʻalolo.
Hiki ke ʻike ʻia kekahi mau aʻalolo me ka MRI, a hiki iā ʻoe ke ʻike inā he pōʻino a mumū paha i nā aʻalolo ma kekahi mau ʻāpana o ke kino. ʻAʻole hiki iā mākou ke ʻike pololei i ke aʻalolo ma ka CT P scan. Ma ka CT, hiki iā mākou ke ʻike i ka iwi a puni ke aʻalolo a i ʻole ka ʻiʻo a puni ke aʻalolo e ʻike inā he hopena ko lākou ma kahi a mākou e manaʻo ai e noho ai ke aʻalolo. Akā no ka nānā pololei ʻana i nā aʻalolo, ʻoi aku ka maikaʻi o ka MRI.
ʻAʻole maikaʻi loa nā MRI i ka nānā ʻana i kekahi mau mea ʻē aʻe, e like me nā iwi, ke koko, nā māmā a me nā ʻōpū. E hoʻomanaʻo e hilinaʻi nui ana ka MRI i ka hoʻohana ʻana i nā magnet e hoʻohuli i ka hydrogen i loko o ka wai i loko o ke kino. ʻO ka hopena, ʻaʻole ʻike ʻia nā mea paʻa e like me nā pōhaku puʻupaʻa a me nā iwi. ʻAʻole hoʻi nā mea i piha i ka ea, e like me kou mau māmā.
MRI: Pōpilikia kūpono
ʻOiai paha he ʻano hana maikaʻi ka MRI no ka nānā ʻana i kekahi mau ʻano o ke kino, ʻaʻole ia no nā mea āpau.
Inā he ʻano metala kou i loko o kou kino, ʻaʻole hiki ke hana ʻia kahi MRI. ʻO kēia no ka mea he magnet maoli ka MRI, no laila hiki ke hoʻopilikia i kekahi mau mea hoʻokomo metala. ʻO kēia kekahi me kekahi mau pacemakers, defibrillators a i ʻole nā mea hana shunt.
ʻO nā metala e like me nā pani hono he palekana ia no MR. Akā ma mua o ka loaʻa ʻana o kahi scan MRI, e hōʻoia i ka ʻike o kāu mea lawelawe i nā metala i loko o kou kino.
Eia kekahi, koi ʻia ʻoe e noho mālie no kekahi manawa, kahi mea hiki ʻole i kekahi poʻe ke ʻae. No kekahi poʻe, hiki i ke ʻano pani o ka mīkini MRI ke hoʻoulu i ka hopohopo a i ʻole ka claustrophobia, ka mea e paʻakikī ai ke kiʻi ʻana.
ʻOi aku ka maikaʻi o kekahi ma mua o kekahi?
ʻAʻole ʻoi aku ka maikaʻi o ka CT a me ka MRI i nā manawa a pau, he mea ia o ka mea āu e ʻimi nei a pehea kou ʻae ʻana i nā mea ʻelua. I nā manawa he nui, manaʻo ka poʻe he ʻoi aku ka maikaʻi o kekahi ma mua o kekahi. Akā, pili maoli ia i ka nīnau a kāu kauka.
ʻO ka hopena: Inā kauoha kāu mea mālama ola i kahi CT a MRI paha, ʻo ka pahuhopu ka hoʻomaopopo ʻana i ka mea e hana nei i loko o kou kino i mea e hāʻawi ai iā ʻoe i ka lāʻau maikaʻi loa.
