Abstract

Purpose: To evaluate if different iodine concentrations of a contrast material (c.m.) have an impact on abdominal enhancement in VIS-CT during the arterial (AP) and portal venous phase (PVP). Materials and Methods: 75 patients underwent biphasic CT of the abdomen. They were assigned to three equally sized groups. For all patients a non-ionic c.m. (iopromide, Ultravist, Schering AG, Berlin) with different iodine concentrations and,a constant total iodine load of 37 g with an injection flow rate of 4 ml/s was used. The volume of the c.m. differed depending on the iodine concentrations: group 1 (123 ml of 300 mgl/ml); group 2 (112 ml of 335 mgl/ml); group 3 (100 ml of 370 mgl/ml). The scan delay was optimized by using a bolus tracking device. The groups were compared concerning their mean enhancement of aorta, spleen, pancreas, and liver in the AP and PVR Results: The comparison of the three groups showed an improved enhancement in aorta, spleen, and pancreas during the AP by using the higher c.m. concentrations. In the PVP the c.m. enhancement of aorta, liver, spleen, and pancreas was independent of the administered c.m. concentration. Conclusion: Higher iodine concentrations of c.m. have a positive impact on abdominal enhancement during the AIR The concentration has no influence on the enhancement during the PVP of abdominal MS-CT.
