Zowonera zosiyanandi gulu la mankhwala opangidwa kuti athandize kuzindikira matenda mwa kukonza njira yowunikira zithunzi. Zida zowunikira zithunzi zosiyanasiyana zapangidwa pa njira iliyonse yowunikira zithunzi, komanso njira iliyonse yoperekera mankhwala.
"Kusiyanitsa zinthu ndikofunika kwambiri pa phindu (komwe) njira yojambulira zithunzi imawonjezera," adatero Dushyant Sahani, MD, mu mndandanda wamavidiyo aposachedwa oyankhulana ndi Joseph Cavallo, MD, MBA.
Kugwiritsa Ntchito Kwambiri
Pa computed tomography (CT), magnetic resonance imaging (MRI) ndi positron emission tomography computed tomography (PET/CT), contrast media imagwiritsidwa ntchito m'mayeso ambiri awa a kujambula zithunzi za mtima ndi khansa m'madipatimenti odzidzimutsa.
Zopangira Kusiyana kwa Zinthu Zosiyanasiyana
Pali mitundu yambiri ya zinthu zosiyanitsa zomwe zimagwiritsidwa ntchito m'madipatimenti osiyanasiyana ojambulira zithunzi zachipatala.
Barium sulfateZowonera zosiyanitsa mitundu zakhala zikugwiritsidwa ntchito kwa zaka zambiri. Nthawi zambiri zimagwiritsidwa ntchito poyesa x-ray ndi fluoroscopic. Nthawi zina zimagwiritsidwanso ntchito poyesa CT ya GI tract. Ndi zotsika mtengo ndipo zimaloledwa bwino ndi odwala ambiri, mavuto omwe amabwera chifukwa chogwiritsa ntchito ndi osowa.
Zosakaniza zosiyana ndi ayodiniNdi zinthu zosiyanitsa zomwe zimakhala ndi maatomu a ayodini omwe amagwiritsidwa ntchito pojambula zithunzi za x-ray, fluoroscopic, angiographic ndi CT. Ndi gulu la zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito popereka chithandizo kudzera m'mitsempha, pakamwa ndi njira zina. Zingagwiritsidwenso ntchito mu fluoroscopy, angiography ndi venography, ndipo nthawi zina, plain radiography.
MRI yosiyana ndi zinthu zinaKawirikawiri ndi mankhwala oletsa kusiyanitsa omwe amagwiritsidwa ntchito pogwiritsa ntchito gadolinium-based contrast agents (GBCAs), omwe amagwiritsidwa ntchito poyesa MRI yambiri yolimbitsa kusiyanitsa. M'mbuyomu, nthawi zina ankagwiritsidwa ntchito poyesa mitsempha yamagazi ndi CT koma chifukwa cha poizoni wa nephrotoxicity, kugwiritsa ntchito kumeneku kwasiyidwa (kwambiri).
Zojambula zosiyanitsa za Ultrasoundakhala akutchuka kwambiri m'zaka zaposachedwapa pa ntchito zina zapadera.
Kodi zotsatira zake zingakhale zotani ngati mutalandira jakisoni wa contrast?
Nthawi zambiri zimachitika msanga chifukwa cha utoto, koma nthawi zina ziphuphu zofiira komanso zoyabwa zimatha kuchitika m'thupi maola angapo mutajambula. Izi sizichitika kawirikawiri, koma ngati zitachitika, muyenera kulankhulana ndi dokotala wanu kapena dipatimenti ya A&E yapafupi.
Zina mwa zinthu zomwe zimachitika kawirikawiri koma zomwe zingachedwetsedwe ndi monga nseru, kusanza, kupweteka m'mimba, ziphuphu, chizungulire ndi mutu. Zizindikiro zimenezi nthawi zambiri zimatha pakatha maola ochepa ndipo nthawi zambiri pamafunika chithandizo chochepa kapena palibe chithandizo chilichonse.
Chojambulira Zinthu Zosiyana
Zojambulira Zosiyanitsa Zinthuamagwiritsidwa ntchito pobaya zinthu zotsutsana kapena zinthu zotsutsana kuti magazi ndi magazi aziyenda bwino m'thupi. Zinthu zotsutsana nthawi zambiri zimatchedwa 'dye' chifukwa zimathandiza kuti mitsempha, mitsempha yamagazi ndi ziwalo zamkati ziwonekere bwino pazithunzi zojambulidwa. Zonsezi zimachitika chifukwa cha thandizo lajekeseni ya kuthamanga kwambiris. LnkMed yawulula kampani yakejekeseni imodzi ya CT, Injector ya mutu wa CT iwiri, Jakisoni wa MRI, Injector ya angiographyKulowa msika pang'onopang'ono kuyambira pomwe idakhazikitsidwa mu 2018 ndipo tapeza makasitomala ambiri.
