Midhiya yekusiyanisaiboka remakemikari akagadzirwa kubatsira mukuongorora chirwere nekuvandudza kusiyanisa kwemuchina wekutora mifananidzo. Michina yakasiyana-siyana yakagadzirwa yemhando yega yega yekutora mifananidzo, uye nzira yega yega yekupa mifananidzo.
"Kusiyanisa mifananidzo kwakakosha zvikuru pakukosha (zvichireva kuti) nzira yekufungidzira inowedzera," akadaro Dushyant Sahani, MD, muhurukuro yevhidhiyo yakaitwa nguva pfupi yadarika naJoseph Cavallo, MD, MBA.
Kushandiswa Kwakakura
Pa computed tomography (CT), magnetic resonance imaging (MRI) uye positron emission tomography computed tomography (PET/CT), contrast media inoshandiswa muzvizhinji zvezviedzo izvi zvekufungidzira kwemoyo nekenza mumadhipatimendi e emergency.

Kune mhando dzakawanda dzemifananidzo yekuenzanisa inoshandiswa mudhipatimendi rakasiyana remifananidzo yezvokurapa.
Barium sulfateMichina yekuenzanisa yave ichishandiswa kwemakumi emakore. Kushandiswa kwayo kunowanzo shandiswa pakuongororwa kweX-ray neFluoroscopic. Dzimwe nguva inoshandiswawo pakuongororwa kweCT yeGI tract. Haidhuri uye inoshivirirwa zvakanaka nevarwere vazhinji, matambudziko anokonzerwa nekushandiswa kwayo haawanzoitiki.
Midhiya yekusiyanisa ine iodinendiwo ma "contrast agents" ane maatomu eaiodine anoshandiswa pakuongorora x-ray, fluoroscopic, angiographic uye CT imaging. Iboka remishonga inoshandiswa nenzira dzakasiyana-siyana inoshandiswa pakurapa netsinga, nemuromo uye nedzimwe nzira dzekuisa. Inogona zvakare kushandiswa mu fluoroscopy, angiography uye venography, uye dzimwe nguva, plain radiography.
MRI midhiya yakasiyana-siyanaanowanzo shandiswa gadolinium-based contrast agents (GBCAs), ayo anoshandiswa pakuongorora MRI kwakawanda. Kare, dzimwe nguva aishandiswa pakuongorora tsinga dzeropa neCT asi nekuda kwekusashanda zvakanaka kwemasero aya, kushandiswa uku (kwakanyanya) kwakaregwa.
Ultrasound contrast mediavanga vachinyanya kufarirwa mumakore achangopfuura nekuda kwekushandiswa kwakajairika.
Ndezvipi zvingaitika kana munhu akapihwa jekiseni re contrast?
