ABSTRACT
A randomized double-blind crossover study using Omnipaque 350 mg l/ml (iohexol) and Hexabrix 320 mg l/ml (ioxaglate) in 53 patients undergoing intravenous digital subtraction angiography of the carotid arteries revealed no significant differences in image quality. Some differences were found in subjective side effects that favored Omnipaque. Nausea was reported in four patients after injection of Hexabrix, and a metallic taste was significantly more frequent (p less than 0.01) with this contrast medium. The patients' preference for Omnipaque was also statistically significant (p less than 0.01). It was concluded that both contrast media are suitable for intravenous digital subtraction angiography.

CT was performed before and after lymphadenectomy in 105 patients with early stage non-seminomatous testicular tumor. Retroperitoneal blurring and retracted bowel were the most common findings and might cause interpretation problems. A reference CT making future comparison possible should be routinely performed two months after the operation.

An anastomosis between the left renal and left ascending lumbar veins may appear as a mass on CT scans due to a varicosity where the veins separate. Intravenous injection of contrast material reveals the vascular nature of the mass.
