Two types of protocols used based on MDCT scanner parameters: Two scout views corresponding to a 64-slice scanner (a) and 320- slice scanner (b) demonstrate the approach to data acquisition. First, the gated (yellow rectangle) part of the exam is obtained, including only cardiac CTA with the 64-slice scanner and gated CTA of the chest with the 320-slice scanner. The second step (red rectangle) corresponds to CTA chest, abdomen and pelvis in the first scenario (a) and CT abdomen and pelvis in the second (b). Note that in both cases eventually the entire torso is imaged
