Is the quality of evaluation of the arteries of the lower extremities better with a wide detector MDCT scanner?
Asked differently, is a 256-detector MDCT scanner better than a 64-detector MDCT scanner to assess the lower extremity arteries? Not necessarily. The acquisition time of wide-detector MDCT scanners is shorter and could lead to outrunning of the contrast bolus. That is, the scan could reach the lower extremities before the contrast material has arrived in this location.
