Imidiya yokwahlulahlulaZiliqela leekhemikhali ezenzelwe ukunceda ekuchazeni isifo ngokuphucula isisombululo sokungafani kwendlela yokujonga imifanekiso. Iindlela ezithile zokwahlulahlula ziye zaphuhliswa kuzo zonke iindlela zokujonga imifanekiso, kunye nayo yonke indlela enokucingelwa yokulawula.
“I-contrast media ibaluleke kakhulu kwixabiso (kangangokuba) indlela yokujonga imifanekiso iyongeza,” utshilo uDushyant Sahani, MD, kuthotho lwevidiyo yodliwanondlebe noJoseph Cavallo, MD, MBA kutshanje.
Ukusetyenziswa Okubanzi
Kwi-computed tomography (CT), i-magnetic resonance imaging (MRI) kunye ne-positron emission tomography i-computed tomography (PET/CT), i-contrast media isetyenziswa kuninzi lwezi vavanyo ze-cardiovascular imaging kunye ne-oncology imaging kwiisebe ezingxamisekileyo.
Iiarhente zokungafaniyo ngeenjongo ezahlukeneyo
Kukho iintlobo ezininzi zemidiya yokwahlulahlula esetyenziswa kwiicandelo ezahlukeneyo zemifanekiso yezonyango.
I-Barium sulfateIi-contrast media bezisetyenziswa amashumi eminyaka. Ukusetyenziswa kwazo kudla ngokukhawulelwa kwiimviwo ze-radiographic kunye ne-fluoroscopic. Ngamanye amaxesha zikwasetyenziswa novavanyo lwe-CT lwe-GI tract. Zixabiso eliphantsi kwaye zinyanyezelwa kakuhle zizigulane ezininzi, iingxaki zokusetyenziswa kwazo azixhaphakanga.
Imidiya yokungafani ene-iodinezii-arhente zomahluko eziqulethe ii-athomu ze-iodine ezisetyenziselwa i-radiographic, i-fluoroscopic, i-angiographic kunye ne-CT imaging. Ziliqela leearhente ezisetyenziswa ngeendlela ezahlukeneyo zokusetyenziswa ngemithambo yegazi, ngomlomo nakwezinye iindlela zokusetyenziswa. Zingasetyenziswa nakwi-fluoroscopy, i-angiography kunye ne-venography, kwaye ngamanye amaxesha, i-radiography ecacileyo.
Imidiya yokungafani kwe-MRIZii-arhente ezisebenzisa i-gadolinium-based contrast agents (GBCAs), eziziiarhente ezisetyenziswa kwi-MRI scans ezininzi ezisebenzisa i-contrast-enhanced. Ngokwembali, zazisetyenziswa ngamanye amaxesha kwi-vascular and CT scans kodwa ngenxa ye-nephrotoxicity, olu setyenziso luye lwayekwa (kakhulu).
Imidiya yokungafani kwe-ultrasoundziye zathandwa kakhulu kwiminyaka yakutshanje ngenxa yezicelo ezithile.
Zithini iziphumo ezinokubakho xa ufumana inaliti ye-contrast?
Naluphi na uphendulo kwidayi ludla ngokuba lolwexesha elifutshane, kodwa ngamanye amaxesha irhashalala ebomvu nerhawuzelelayo (i-allergy reaction encinci) inokukhula emzimbeni emva kweeyure ezimbalwa emva kokuskena. Oku kunqabile kakhulu, kodwa ukuba kuyenzeka, kufuneka uqhagamshelane nogqirha wakho okanye isebe le-A&E lasekuhlaleni.
Ezinye iimpendulo ezingaqhelekanga kodwa ezinokwenzeka emva kwexesha ziquka isicaphucaphu, ukuhlanza, iintlungu zesisu, ukurhawuzelela, isiyezi kunye nentloko ebuhlungu. Ezi mpawu zihlala zinyamalala kwiiyure ezimbalwa kwaye ngesiqhelo kufuneka unyango oluncinci okanye kungabikho kwaphela.
I-Contrast Media Injector
Ii-Contrast Media Injectorszisetyenziselwa ukufaka i-contrast media okanye ii-contrast agents ukuphucula igazi kunye nokuphuma kwamanzi kwizicwili. I-contrast idla ngokuchazwa njenge-'dye' njengoko ivumela imithambo, imithambo yegazi kunye nezitho zangaphakathi ukuba zibonakale ngokucacileyo kwimifanekiso yeskeni. Konke oku kungenxa yoncedo lweinjector yoxinzelelo oluphezulus. I-LnkMed ityhile i-akhawunti yayoI-CT single injector, I-CT double head injector, Inaliti ye-MRI, I-Angiography injectorIngene kwimarike inyathelo ngenyathelo ukusukela oko yasekwa ngo-2018 kwaye sifumene abathengi abaninzi.
