ʻO ke kumu o kēia ʻatikala e kūkākūkā i nā ʻano kaʻina hana kiʻi olakino e huikau pinepine ʻia e ka lehulehu, X-ray, CT, a me MRI.
Haʻahaʻa haʻahaʻa haʻahaʻa-X-ray
Pehea i loaʻa ai ka inoa o ka X-ray?
Hoʻihoʻi ia iā mākou i nā makahiki 127 a hiki i Nowemapa. ʻO ka German physicist Wilhelm Conrad Roentgen i ʻike i kahi mea i ʻike ʻole ʻia i loko o kāna keʻena haʻahaʻa haʻahaʻa, a laila ua hoʻopau ʻo ia i nā hebedoma i loko o ka hale keʻena, ua hoʻoholo maikaʻi ʻo ia i kāna wahine e hana ma ke ʻano he kumuhana hoʻāʻo, a hoʻopaʻa ʻia i ka X-ray mua i ka mōʻaukala kanaka, no ka mea, ʻo ka mālamalama. piha i nā mea pohihihi ʻike ʻole ʻia, ua kapa ʻia ʻo Roentgen iā X-ray. Ua hoʻokumu kēia ʻike nui i ke kumu no ka maʻi a me ka mālama ʻana i ka lāʻau lapaʻau e hiki mai ana. ʻO Nowemapa 8, 1895, ua hoʻolaha ʻia ka International Radiological Day no ka hoʻomanaʻo ʻana i kēia ʻike epoch-making.
ʻO ka X-ray he kukui ʻike ʻole ʻia me ka lōʻihi hawewe pōkole ʻo ia ka pāhawewe electromagnetic ma waena o nā kukuna ultraviolet a me ka gamma. I ka manawa like, ikaika loa kona hiki ke komo, ma muli o ka ʻokoʻa o ka density a me ka mānoanoa o nā ʻano kikoʻī like ʻole o ke kino kanaka, ua komo ka X-ray i nā degere like ʻole i ka wā e hele ai i loko o ke kino kanaka, a me ka X- ʻO ka ray me nā ʻike atenuation ʻē aʻe ma hope o ke komo ʻana i ke kino o ke kanaka e hele i ke ʻano o nā ʻenehana hoʻomohala, a ma hope e hana i nā kiʻi kiʻi ʻeleʻele a keʻokeʻo.
Hoʻohui pinepine ʻia nā kukui X a me CT, a loaʻa iā lākou nā mea like a me nā ʻokoʻa. Loaʻa nā mea ʻelua i ka loina kiʻi, hoʻohana lāua ʻelua i ke komo ʻana i ka X-ray e hana i nā kiʻi ʻeleʻele a me ke keʻokeʻo me ka ikaika attenuation ʻokoʻa o ka radiation ma o nā kino kanaka me nā ʻano kiko a me ka mānoanoa. Akā aia kekahi mau ʻokoʻa maopopo.
ʻO ka mua, ka ʻokoʻawahaheei ka helehelena a me ka hana ana o na mea hana. ʻOi aku ka like o ka X-ray me ka hele ʻana i ke keʻena kiʻi paʻi kiʻi. ʻO ka mea mua, kōkua ʻia ka mea maʻi me ka hoʻonohonoho maʻamau o ke kahua hoʻokolokolo, a laila hoʻohana ʻia ka pahu X-ray (kamepiula nui) e pana i ke kiʻi i hoʻokahi kekona. ʻO nā mea hana CT e like me ka "donut" nui i ka nānā aku, a pono ka mea hoʻokele e kōkua i ka mea maʻi ma ka moena hoʻokolokolo, komo i ka lumi hana, a hana i kahi CT scan no ka mea maʻi.
ʻO ka lua, ʻo ka ʻokoʻawahaheei nā ʻano kiʻi kiʻi. ʻO ke kiʻi X-ray he kiʻi hili ʻelua ʻāpana, a hiki ke kiʻi ʻia ka ʻike kiʻi o kahi kuhikuhi ma ka pana hoʻokahi, he ʻaoʻao hoʻokahi. Ua like ia me ka nānā ʻana i kahi ʻāpana o ka toast i ʻoki ʻole ʻia ma ke ʻano holoʻokoʻa, a ʻaʻole hiki ke hōʻike maopopo ʻia ke ʻano o loko. Hoʻokumu ʻia ke kiʻi CT me ke ʻano o nā kiʻi tomography, ua like ia me ka wehe ʻana i ka papa hana ʻiʻo ma ka papa, maopopo a hoʻokahi e hōʻike i nā kikoʻī hou aʻe a me nā hale i loko o ke kino kanaka, a ʻoi aku ka maikaʻi o ka hoʻonā ma mua o ka X- ray film.
ʻO ke kolu, i kēia manawa, ua palekana a maturely hoʻohana ʻia nā kiʻi X-ray i ka ʻike kōkua o nā makahiki iwi o nā keiki, ʻaʻole pono nā mākua e hopohopo nui e pili ana i ka hopena o ka radiation, ʻo ka nui o ka radiation X-ray. Aia kekahi poʻe maʻi e hele mai i ka haukapila no ka mālama orthopedic ma muli o ka trauma, na ke kauka e synthesize i nā pono a me nā hemahema o X-ray a me CT, maʻamau ka koho mua no ka hoʻokolokolo X-ray, a i ka wā hiki ʻole ke X-ray. ʻike ʻia nā ʻeha a ʻaʻole hiki ke ʻike ʻia, ʻike ʻia ʻo CT ma ke ʻano he kōkua hoʻoikaika.
Mai huikau i ka MRI me ka X-ray a me CT
MRIʻano like me ka CT ma ka helehelena, akā ʻo kona puka hohonu a me nā puka liʻiliʻi e lawe mai i ke ʻano o ke kaomi i ke kino o ke kanaka, ʻo ia kekahi o nā kumu e makaʻu ai ka poʻe he nui.
ʻOkoʻa loa kona kumukānāwai mai ka X-ray a me CT.
Ua ʻike mākou ua haku ʻia ke kino o ke kanaka i nā ʻātoma, ʻo ka nui o ka wai i loko o ke kino o ke kanaka ka mea nui loa, aia ka wai i hydrogen protons, i ka wā e moe ai ke kino o ke kanaka i ke kahua magnetic, aia kahi hapa o ka hydrogen protons a me ka pulse. ʻO ka hōʻailona o ke kahua magnetic waho "resonance", ke alapine i hana ʻia e ka "resonance" i loaʻa i ka mea hoʻokipa, a ma hope o ka hana ʻana o ke kamepiula i ka hōʻailona resonance nāwaliwali, e hana ana i kahi kiʻi kiʻi ʻeleʻele a keʻokeʻo.
ʻIke ʻoe, ʻaʻohe pōʻino radiation ka nuclear magnetic resonance, ʻaʻohe ionizing radiation, ua lilo i ʻano hana kiʻi maʻamau. No nā ʻiʻo palupalu e like me ka ʻōnaehana nerve, nā hono, nā ʻiʻo a me ka momona, makemake ʻia ʻo MRI.
Eia nō naʻe, ʻoi aku ka nui o nā contraindications, a ʻoi aku ka haʻahaʻa o kekahi mau hiʻohiʻona i ka CT, e like me ka nānā ʻana i nā nodules pulmonary liʻiliʻi, nā haki, a me nā mea ʻē aʻe. No laila, inā e koho i ka X-ray, CT a i ʻole MRI, pono ke kauka e koho i nā hōʻailona.
Eia kekahi, hiki iā mākou ke manaʻo i nā lako MRI he magnet nui, e hāʻule nā lako uila kokoke iā ia, e hoʻopili koke ʻia nā mea metala kokoke iā ia, e hopena i kahi "missile effect", weliweli loa.
No laila, he pilikia maʻamau ka palekana o ka hoʻokolokolo MRI no nā kauka. I ka hoʻomākaukau ʻana no ka hoʻokolokolo MRI, pono e haʻi i ke kauka i ka moʻolelo me ka ʻoiaʻiʻo a me ka kikoʻī, e hahai i ke kauoha a nā poʻe loea, a e hōʻoia i ka hoʻokolokolo palekana.
Hiki ke ʻike ʻia kēia mau ʻano ʻekolu o ka X-ray, CT a me MRI i nā kaʻina hana kiʻi lāʻau lapaʻau e hoʻopiha i kekahi i kekahi a lawelawe i nā maʻi.

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.
