Media hoʻohālikelikehe pūʻulu o nā mea kemika i hoʻomohala ʻia e kōkua i ke ʻano o ka pathology ma o ka hoʻomaikaʻi ʻana i ka hoʻonā ʻokoʻa o kahi modality imaging. Ua hoʻomohala ʻia nā pāpaho like ʻole no kēlā me kēia ʻano hana kiʻi kiʻi, a me kēlā me kēia ala o ka hoʻokele.
Hoʻohui nui ʻia ka media contrast i ka waiwai (ʻo ia) i hoʻohui ʻia e ka ʻenehana kiʻi, "i ʻōlelo ai ʻo Dushyant Sahani, MD, i loko o kahi wikiō ninaninau wikiō me Joseph Cavallo, MD, MBA.
Hoʻohana nui
No ka computed tomography (CT), magnetic resonance imaging (MRI) a me positron emission tomography computed tomography (PET/CT), hoʻohana ʻia ka media contrast i ka hapa nui o kēia mau hoʻokolohua no ke kiʻi cardiovascular a me ka oncology imaging i nā keʻena pilikia.
Nā Agena Kūkākūkā no nā kumu like ʻole
Nui nā ʻano media ʻokoʻa i hoʻohana ʻia i loko o nā keʻena kiʻi lāʻau like ʻole.
Barium sulfateua hoʻohana ʻia ka media contrast no nā makahiki he nui. Hoʻohana ʻia kā lākou hoʻohana i nā hoʻokolohua radiographic a me fluoroscopic. I kekahi manawa, hoʻohana ʻia lākou no ka nānā ʻana i ka CT o ka ʻāpana GI. He mea liʻiliʻi lākou a ʻae maikaʻi ʻia e ka hapa nui o nā maʻi.
Media hoʻohālikelike iodinatedʻO ia nā mea ʻokoʻa i loaʻa nā ʻātoma iodine i hoʻohana ʻia no ka radiographic, fluoroscopic, angiographic a me CT imaging. He pūʻulu maʻamau lākou i hoʻohana ʻia no ka intravenous, waha a me nā ala ʻē aʻe o ka hoʻokele. Hiki iā lākou ke hoʻohana i ka fluoroscopy, angiography a me ka venography, a i kekahi manawa, ka lekiō maʻamau.
MRI ʻokoʻa mediaʻo ia ka mea maʻamau i ka gadolinium-based contrast agents (GBCAs), ʻo ia nā mea hana i hoʻohana ʻia no ka hapa nui o nā scans MRI hoʻonui ʻokoʻa. ʻO ka mōʻaukala, ua hoʻohana ʻia lākou no nā vascular a me CT scans akā ma muli o ka nephrotoxicity ua haʻalele ʻia kēia hoʻohana.
ʻO ka pāpaʻi hoʻohālikelike kani kaniua loaʻa ka mana i nā makahiki i hala iho nei no nā noi niche maʻamau.
He aha nā hopena e hiki mai ana mai ka loaʻa ʻana o kahi injection of contrast?
Hiki ke hoʻololi koke ʻia kēlā me kēia mea i ka wai, akā i kekahi manawa, hiki ke ulu i ke kino i kekahi mau hola ma hope o ka nānā ʻana. He mea kakaikahi loa kēia, akā inā loaʻa ia, pono ʻoe e kelepona i kāu GP a i ʻole ke keʻena A&E kūloko.
ʻO nā hopena ʻē aʻe kakaʻikahi akā hiki ke hoʻopaneʻe ʻia, ʻo ia ka nausea, ka luaʻi, ka ʻeha ʻōpū, ka ʻeha, ka ʻūlū a me ke poʻo.
Mea hoʻolele Media Contrast
ʻO nā mea hoʻopili Media Contrasthoʻohana ʻia e hoʻokomo i ka media ʻokoʻa a i ʻole nā mea hoʻohālikelike e hoʻomaikaʻi i ke koko a me ka perfusion i loko o nā kiko. Hōʻike pinepine ʻia ka ʻokoʻa ma ke ʻano he 'dye' no ka mea e hiki ai i nā veins, arteries a me nā ʻāpana o loko ke hōʻike maʻalahi i nā kiʻi scan. Mahalo kēia i ke kōkua okiʻekiʻe kaomi injectors. Ua wehe ʻo LnkMed i kānaCT hoʻokahi injector, CT pālua poʻo injector, mea hoʻokomo MRI, ʻO ka injector angiographyi loko o ka mākeke i kēlā me kēia pae mai kona hoʻokumu ʻana i 2018 a ua loaʻa iā mākou nā mea kūʻai aku he nui.
