Imidiya yokuqhathanisaziyiqembu lama-chemical agents aklanyelwe ukusiza ekuchazeni i-pathology ngokuthuthukisa ukuxazululwa kokungafani kwendlela yokuthwebula izithombe. Kuye kwaklanywa imidiya ethile yokuqhathanisa yazo zonke izindlela zokuthwebula izithombe zesakhiwo, kanye nayo yonke indlela yokuphatha engacatshangwa.
"Imidiya yokuqhathanisa ibaluleke kakhulu enanini (kangangokuthi) ubuchwepheshe bokuthwebula izithombe bunezela," kuphawula uDushyant Sahani, MD, ochungechungeni lwamavidiyo asanda kuxoxwa noJoseph Cavallo, MD, MBA.
Ukusetshenziswa Okubanzi
Ku-computed tomography (CT), i-magnetic resonance imaging (MRI) kanye ne-positron emission tomography i-computed tomography (PET/CT), i-contrast media isetshenziswa ezivivinyweni eziningi ze-cardiovascular imaging kanye ne-oncology imaging eminyangweni yezimo eziphuthumayo.
Ama-Contrast Ejenti Ngezinhloso Ezihlukene
Kunezinhlobo eziningi zemidiya yokuqhathanisa esetshenziswa eminyangweni ehlukene yezithombe zezokwelapha.
I-Barium sulfateImidiya yokuqhathanisa ibilokhu isetshenziswa amashumi eminyaka amaningi. Ukusetshenziswa kwayo ngokuvamile kukhawulelwe ekuhlolweni kwe-x-ray kanye ne-fluoroscopic. Ngezinye izikhathi isetshenziselwa nokuhlolwa kwe-CT kwe-GI tract. Ishibhile futhi ibekezelelwa kahle yiziguli eziningi, izinkinga zokusetshenziswa kwayo azivamile.
Imidiya yokungafani ene-iodineyizinto ezihlukanisayo eziqukethe ama-athomu e-iodine asetshenziselwa i-x-ray, i-fluoroscopic, i-angiographic kanye ne-CT imaging. Ziyiqembu lezinto ezisebenziseka ngezindlela eziningi ezisetshenziselwa izindlela zokuphatha ngemithambo yegazi, ngomlomo kanye neminye. Zingasetshenziswa futhi ku-fluoroscopy, i-angiography kanye ne-venography, ngisho nangezinye izikhathi, i-radiography ecacile.
Imidiya yokungafani kwe-MRINgokuvamile ama-gadolinium-based contrast agents (GBCAs), okuyizinto ezisetshenziswa kakhulu kuma-MRI scan amaningi athuthukisiwe. Ngokomlando, ayesetshenziswa ngezikhathi ezithile kuma-vascular kanye nama-CT scan kodwa ngenxa yobuthi obungabangelwa yi-nephrotoxicity lokhu kusetshenziswa kuye kwashiywa (ikakhulukazi).
Imidiya yokungafani kwe-Ultrasoundbebelokhu bethandwa kakhulu eminyakeni yamuva nje ngenxa yezinhlelo zokusebenza ezihlukile.
Yimiphi imiphumela engaba khona ngokuthola umjovo we-contrast?
Noma yikuphi ukusabela kudayi kuvame ukuba khona ngokushesha, kodwa ngezinye izikhathi ukuqubuka okubomvu nokulumayo (ukusabela okuncane kokungezwani komzimba) kungavela emzimbeni emahoreni ambalwa ngemva kokuskena. Lokhu akuvamile kakhulu, kodwa uma kwenzeka, kufanele uxhumane nodokotela wakho noma umnyango we-A&E wendawo.
Ezinye izindlela ezingavamile kodwa ezingase zibambezeleke zifaka phakathi isicanucanu, ukuhlanza, ubuhlungu besisu, ukuqubuka, isiyezi kanye nekhanda elibuhlungu. Lezi zimpawu cishe ziyanyamalala njalo phakathi namahora ambalwa futhi ngokuvamile kudingeka ukwelashwa okuncane noma akukho nhlobo.
I-Contrast Media Injector
Ama-Injectors e-Contrast Mediazisetshenziselwa ukufaka i-contrast media noma ama-contrast agents ukuze kuthuthukiswe igazi kanye nokugeleza kwegazi ezicutshini. I-contrast ivame ukuchazwa ngokuthi 'udayi' njengoba ivumela imithambo yegazi, imithambo yegazi kanye nezitho zangaphakathi ukuthi zibonakale ngokucacile ezithombeni eziskeniwe. Konke lokhu kungenxa yosizo lwe-umjovo wokucindezela okuphezulus. I-LnkMed iveze i-Umjovo owodwa we-CT, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo we-MRI, Umjovo we-AngiographySingene emakethe isinyathelo ngesinyathelo selokhu yasungulwa ngo-2018 futhi sithole amakhasimende amaningi.
