Abstract
By sequential CT scanning, the dynamics of intravenously injected contrast medium were observed in 21 patients with abdominal malignancies. Within 30 sec, and one breath, four sequential cuts of the same section were obtained. The corticomedullary junction of the kidney was clearly delineated in the early phase, and tumor vascularity was well appreciated within vascularized malignancies. Angiographic CT was found to be superior to conventional CT and is promising in the assessment of the nature of abdominal tumors. In some cases, use of CT angiography may enable deferring catheter angiography.
