Localization of PA by adrenal vein sampling (AVS) was necessary, but angiography with iodine contrast medium was not possible because of her allergy. AVS was performed using gadolinium contrast agent (gadoterate meglumine) instead of iodine, in combination with computed tomography angiography (CTA) ...
A case study reported GBCA-induced delayed hypersensitivity reaction (> 1 h after GBCA administration) in a 64 YOF patient, who underwent a contrast-enhanced MRI scan for suspected osteomyelitis of the paranasal sinuses [17A]. Incidentally, she reported an allergy to ICAs. Hence, the GBCA (gad...
contrast agents in patients with known contrast allergy. The radio-opacity of gadolinium is less than that of iodinated contrast agents, which results in a less distinct appearance on fluoroscopic images. Regardless, the injection of 1–3 mL of undiluted gadopentate dimeglumine (Magnevi...

Iodinated contrast media can rarely cause severe allergic reactions during nonvascular urologic imaging procedures. Alternatives like gadolinium-based contrast may help mitigate this risk in susceptible patients. A 66-year-old woman with a documented iod

Nephrogenic systemic fibrosis (NSF), a severe systemic fibrosing disorder, predominantly afflicts individuals with advanced renal dysfunction. NSF has been strongly associated with exposure to gadolinium-based contrast agents (GBCAs), which were once bel
