Phillips brilliance ict 256

CECT was performed using the following equipment: Toshiba Aquilion One, Phillips Brilliance iCT 256 (Philips Medical Systems) or Toshiba Aquilion 64 (Toshiba Medical Systems) scanners. The scanning parameters were as follows: tube voltage, 120 kVp; tube current, 200–250 mA; detector collimation, 64, 256 or 320 × 0.625 mm; field of view, 350 × 350 mm; matrix, 512 × 512; reconstructed slice thickness, 2 mm. After a routine unenhanced scan, we injected contrast material intravenously at a flow rate of 3.0 mL/s to obtain CECT images. Hepatic arterial phase CT images were obtained 30 s after injection. Through preprocessing, images were resampled to a volume of 1.0 mm*1.0 mm *1.0 mm to standardize the voxel spacing.

Contrast-enhanced CT images were acquired from Toshiba Aquilion One, Toshiba Aquilion 64 (Toshiba Medical Systems) or Phillips Brilliance iCT 256 (Philips Medical Systems) scanners. The scanning parameters were as follows: 120 kVp; 100–200 mAs; detector collimation of 64, 256, or 320 × 0.625 mm; field of view of 350 × 350 mm; matrix of 512 × 512 and reconstructed slice thickness of 2 mm. Contrast-enhanced CT scanning was performed with a 25-s delay after the injection of 85 ml of non-ionic iodinated contrast material (350 mg iodine/ml, Omnipaque, GE Healthcare). All images were exported to the Picture Archiving and Communication System (PACS) workstation (IMPAX, AGFA).
