ABSTRACT: Purpose: To
evaluate the quality of three-dimensional (3D) CT angiography images of the
abdominal viscera with small focal spot, low tube voltage, and iterative model
reconstruction technique (IMR). Materials and Methods: Seven patients with
suspected disease of the pancreatobiliary system had undergone CT with
high-quality CTA protocol in the present study. There were 5 men and 2 women, ranging
in age from 52 to 80 years (mean: 64 years). Results: Depiction of abdominal
small artery, small portal vein was possible in all cases. In two cases that we
were able to compare, it was superior to standard CTA in small vascular
depiction in CTA made clearly in high quality protocol. Conclusions: Although
the use of small focal spot, low tube voltage, and IMR can produce
higher-quality images of abdominal vessels than standard CTA, this improvement
is not significant at elevated radiation doses.
