Ultravist 370 mct

All CT examinations of the abdomen were acquired on a dual-layer dual-energy 64-channel CT scanner (IQon, Philips Healthcare, Cleveland, OH, USA) according to our institutional protocol. Contrast material was injected via a 20 G catheter into an ante-cubital vein with a rate of 2,5 ml/s using a dual syringe injection system (Stellant, MEDRAD, Indianola, Pennsylvania), followed by a 50 ml saline chaser. Portal venous phase images were obtained 70 s following intravenous administration of contrast material (80 ml Ultravist 370 MCT, Bayer Vital GmbH, Leverkusen, Germany). The scan was performed craniocaudally with a pitch of 0.9, tube voltage of 120 kVp, a 64x0.625-mm detector configuration, a rotation time of 0.33 seconds and an average CTDIvol of 7.8 mGy. All data sets were reconstructed in axial view with slice thickness of 5 mm and a 512-image matrix with an iDose image reconstruction algorithm level 2.

A dual-layer dual-energy 64-channel CT scanner (IQon, Philips Healthcare, Cleveland, OH, USA) was used for the acquisition of all CT examinations of the abdomen according to our institutional protocol. A 20-G catheter and a dual-syringe injection system (Stellant, MEDRAD, Indianola, Pennsylvania) were used to apply a contrast agent (bolus of 80 ml Ultravist 370 MCT, Bayer Vital GmbH, Leverkusen, Germany). The contrast agent was administered into an ante-cubital vein with a rate of 3 ml/s, followed by a 50-ml saline chaser, and the portal venous phase images were obtained 70 s after the injection. All patients were scanned craniocaudally with a pitch of 0.9, a tube voltage of 120 kVp, and a 64 × 0.625 mm detector configuration. The reconstruction of the data sets was made in axial view using a 512-image matrix and slice thickness of 5 mm.
