Hoʻohana ʻo CT a me MRI i nā ʻano hana like ʻole e hōʻike i nā mea like ʻole - ʻaʻole pono "ʻoi aku" ma mua o kekahi.
Hiki ke ʻike ʻia kekahi mau ʻeha a i ʻole nā kūlana me ka maka ʻōlohelohe. Pono nā poʻe ʻē aʻe i ka ʻike hohonu.
Inā kānalua kāu mea mālama ola i kahi maʻi e like me ke kahe o loko, ka ʻōpū, a i ʻole ka pōʻino ʻiʻo, hiki iā lākou ke kauoha i kahi CT scan a i ʻole MRI.
ʻO ka koho o ka hoʻohana ʻana i kahi CT scan a i ʻole MRI aia i kāu mea mālama ola kino, ʻo ka mea nui i ka mea a lākou e manaʻo ai e loaʻa iā lākou.
Pehea ka hana CT a me MRI? ʻO wai ka mea maikaʻi no ke aha? E nānā pono kākou.
A CT scan, pōkole no ka computed tomography scan, hana ʻia ma ke ʻano he mīkini X-ray 3D. Hoʻohana ka CT scanner i kahi X-ray e hele i ka mea maʻi i kahi mea ʻike i ka wā e kaʻapuni ana a puni ka mea maʻi. Hoʻopaʻa ia i nā kiʻi he nui, a laila hoʻohui ʻia kahi kamepiula e hana i kahi kiʻi 3D o ka mea maʻi. Hiki ke hoʻohana ʻia kēia mau kiʻi ma nā ʻano like ʻole e loaʻa ai ka ʻike kūloko o ke kino.
Hiki i ka X-ray kuʻuna ke hāʻawi i kāu mea hāʻawi i ka nānā ʻana i kahi o nā kiʻi. He kiʻi paʻa.
Akā hiki iā ʻoe ke nānā i nā kiʻi CT e kiʻi i ka maka manu o ka wahi i kiʻi ʻia. A i ʻole e wili a puni e nānā mai mua a i hope a i ʻole ʻaoʻao a i kekahi ʻaoʻao. Hiki iā ʻoe ke nānā i ka papa waho loa o ka ʻāpana. A i ʻole e hoʻonui i loko o ka ʻāpana o ke kino i kiʻi ʻia.
CT Scan: He aha kona ʻano?
ʻO ka loaʻa ʻana o ka CT scan he hana wikiwiki a ʻeha ʻole. E moe ana ʻoe ma luna o kahi pākaukau e neʻe mālie ana ma ka mīkini ʻimi apo. Ma muli o nā koi o kāu mea mālama ola, pono paha ʻoe i nā mea pena like ʻole intravenous. ʻO kēlā me kēia scan ma lalo o hoʻokahi minuke.
CT scan: No ke aha ia?
Ma muli o ka hoʻohana ʻana o nā mea nānā CT i nā kukui X, hiki iā lākou ke hōʻike i nā mea like me nā kukui X, akā me ka pololei. ʻO ka X-ray kahi hiʻohiʻona pālahalaha o kahi wahi kiʻi, ʻoiai hiki i kahi CT ke hāʻawi i kahi kiʻi piha a hohonu.
Hoʻohana ʻia nā kiʻi CT e nānā i nā mea e like me: Nā iwi., Nā Pōhaku, Ke koko, nā ʻōpū, nā māmā, nā pae maʻi maʻi maʻi, nā pilikia o ka ʻōpū.
Hiki ke hoʻohana ʻia ka CT scans e nānā i nā mea i ʻike ʻole ʻia e MRI, e like me ke akemāmā, ke koko, a me ka ʻōpū.
CT scan: Nā pilikia kūpono
ʻO ka hopohopo nui loa i loaʻa i kekahi poʻe me ka CT scans (a me nā X-rays no kēlā mea) ʻo ia ka hiki ke hoʻolaha i ka radiation.
Ua manaʻo kekahi poʻe loea e hiki ke hoʻonui iki i ka maʻi kanesa i kekahi poʻe. Akā hoʻopaʻapaʻa ʻia nā pilikia kūpono. Wahi a ka Food and Drug Administration ma muli o ka ʻike ʻepekema o kēia manawa, ʻo ka pilikia o ka maʻi maʻi mai ka radiation CT "ʻaʻole maopopo loa."
Eia nō naʻe, ma muli o nā pilikia o ka radiation CT, ʻaʻole kūpono nā wahine hāpai i ka CT scan ke ʻole pono.
I kekahi manawa, hiki i nā mea mālama ola ke hoʻoholo e hoʻohana i ka MRI ma kahi o CT e hōʻemi i ka pilikia o ka hoʻolaha ʻana i ka radiation. He ʻoiaʻiʻo loa kēia no nā poʻe me nā kūlana olakino e koi ana i nā pōʻai he nui o ke kiʻi no ka manawa lōʻihi.
MRI
ʻO ka MRI ke kū nei no ka magnetic resonance Imaging. I ka pōkole, hoʻohana ʻo MRI i nā magnet a me nā hawewe lekiō e hana i nā kiʻi i loko o kou kino.
ʻO ke ala pololei o ka hana e pili ana i kahi haʻawina physics lōʻihi. Akā i ka pōkole, ua like ia me kēia: He nui ka wai i loko o ko mākou kino, ʻo ia ka H20. ʻO ka H ma H20 ke kū nei no ka hydrogen. Loaʻa i ka hydrogen nā protons - nā mea i hoʻopiʻi maikaʻi ʻia. ʻO ka mea maʻamau, wili kēia mau protons i nā ʻaoʻao like ʻole. Akā ke hālāwai lākou me kahi magnet, e like me ka mīkini MRI, huki ʻia kēia mau protons i ka magnet a hoʻomaka e laina.
MRI: Pehea ke ano?
ʻO MRI kahi mīkini tubular. He 30 a 50 mau minuke ka MRI maʻamau, a pono ʻoe e noho mālie i ke kaʻina hana. Hiki ke kani ka mīkini, a e pōmaikaʻi paha kekahi poʻe i ka hoʻohana ʻana i nā pepeiao pepeiao 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 hoʻolako, hiki iā lākou ke hoʻohana i nā mea pena like ʻole intravenous.
MRI: No ke aha ia?
He maikaʻi loa ka MRI i ka hoʻokaʻawale ʻana i waena o nā kiko. No ka laʻana, hiki i nā mea hoʻolako ke hoʻohana i ke kino holoʻokoʻa CT e ʻimi i nā maʻi ʻōpū. A laila, hana ʻia kahi MRI e hoʻomaopopo maikaʻi i nā nui i loaʻa ma ka CT.
Hiki i kāu mea hoʻolako ke hoʻohana i ka MRI no ka ʻimi ʻana i ka pōʻino hui a me ka pōʻino aʻalolo.
Hiki ke ʻike ʻia kekahi mau aʻalolo me ka MRI, a hiki iā ʻoe ke ʻike inā loaʻa ka pōʻino a i ʻole ka mumū i nā aʻalolo ma kekahi mau wahi 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 ka wahi a mākou e manaʻo ai e pili ana ke aʻalolo. Akā no ka nānā pono ʻana i nā aʻalolo, ʻoi aku ka maikaʻi o ka MRI.
ʻAʻole maikaʻi loa ka MRI i ka nānā ʻana i kekahi mau mea ʻē aʻe, e like me ka iwi, ke koko, ka māmā a me ka ʻōpū. E hoʻomanaʻo i ka hilinaʻi ʻana o MRI i ka hoʻohana ʻana i nā mea magnet e hoʻoikaika i ka hydrogen i loko o ka wai i loko o ke kino. ʻO ka hopena, ʻaʻole e ʻike ʻia nā mea ʻeleʻele e like me nā pōhaku a me nā iwi. ʻAʻole hoʻi kekahi mea i piha i ka ea, e like me kou māmā.
MRI: Hiki ke pilikia
ʻOiai ʻoi aku ka maikaʻi o ka MRI no ka nānā ʻana i kekahi mau hale o ke kino, ʻaʻole ia no kēlā me kēia.
Inā loaʻa iā ʻoe kekahi mau ʻano metala 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 implants metala. Hoʻopili kēia i kekahi mau mea pacemakers, defibrillators a i ʻole nā mea hana shunt.
ʻO nā metala e like me nā pani pani ʻana he MR-palekana. Akā ma mua o ka loaʻa ʻana o kahi scan MRI, e ʻike pono kāu mea lawelawe i nā metala i loko o kou kino.
Eia kekahi, pono ʻoe i kahi hōʻike MRI e noho mālie no kekahi manawa, ʻaʻole hiki i kekahi poʻe ke ʻae. No nā mea ʻē aʻe, hiki i ke ʻano paʻa o ka mīkini MRI ke hoʻoulu i ka hopohopo a i ʻole claustrophobia, kahi mea paʻakikī loa ke kiʻi.
Ua ʻoi aku ka maikaʻi o kekahi ma mua o kekahi?
ʻAʻole ʻoi aku ka maikaʻi o CT a me MRI i nā manawa a pau, pili ia i kāu mea e ʻimi nei a pehea ʻoe e ʻae ai i nā mea ʻelua. I nā manawa he nui, manaʻo ka poʻe ʻoi aku ka maikaʻi o kekahi ma mua o kekahi. Akā, pili maoli i ka nīnau a kāu kauka.
ʻO ka laina lalo: Inā kauoha kāu mea mālama ola i kahi CT a i ʻole MRI, ʻo ka pahuhopu ke hoʻomaopopo i ka mea e hana nei i kou kino i mea e hāʻawi ai iā ʻoe i ka lāʻau lapaʻau maikaʻi loa.

E like me kā mākou e ʻike ai, ʻaʻole hiki ke hoʻokaʻawale ʻia ka hoʻomohala ʻana o ka ʻoihana kiʻi lāʻau mai ka hoʻomohala ʻana i kahi ʻano o nā mea lapaʻau - nā mea hoʻokalakupua ʻokoʻa a me kā lākou mau mea hoʻohana kākoʻo - i hoʻohana nui ʻia i kēia kahua. Ma Kina, kahi kaulana no kāna ʻoihana hana, nui nā mea hana kaulana ma ka home a ma waho no ka hana ʻana i nā mea hana kiʻi lāʻau, me kaLnkMed. Mai kona hoʻokumu ʻana, ua hoʻomau ʻo LnkMed i ke kahua o nā injectors ʻokoʻa kiʻekiʻe. Alakaʻi ʻia ka hui ʻenekinia o LnkMed e kahi Ph.D. me ka ʻoi aku o ʻumi makahiki o ka ʻike a ua komo nui i ka noiʻi a me ka hoʻomohala ʻana. Ma lalo o kāna alakaʻi, ʻo kaCT hoʻokahi poʻo injector,CT pālua poʻo injector,MRI mea hoʻoheheʻe ʻokoʻa, aʻO ka angiography kiʻekiʻe-pressure contrast agent injectorua hoʻolālāʻia me kēia mau hiʻohiʻona: ke kino ikaika a paʻa, ka maʻalahi a me ka naʻauao o ka hana, nā hana piha, ka palekana kiʻekiʻe, a me ka hoʻolālā lōʻihi. Hiki iā mākou ke hāʻawi aku i nā syringes a me nā paipu i kūpono me kēlā mau inoa kaulana o CT,MRI,DSA injectors Me ko lākou ʻano ʻoiaʻiʻo a me ka ikaika ʻoihana, kono ʻoluʻolu nā limahana āpau o LnkMed iā ʻoe e hele mai e ʻimi i nā mākeke hou aʻe.
