Abstract
Eight Beagle dogs were anesthetized and were imaged using
a single channel helical CT scanner. The contrast medium
used in this study was iohexol (300 mg I/ml) and doses were
0.5 ml/kg for a cine scan, 3 ml/kg for an enhanced scan. The
flow rate for contrast material administration was 2 ml/sec for
all scans. This study was divided into three steps, with
unenhanced, cine and enhanced scans. The enhanced scan
was subdivided into the arterial phase and the venous phase.
All of the enhanced scans were reconstructed in 1 mm
intervals and the scans were interpreted by the use of
reformatted images, a cross sectional histogram, maximum
intensity projection and shaded surface display. For the cine
scans, optimal times were a 9-sec delay time post IV injection
in the arterial phase, and an 18-sec delay time post IV
injection in the venous phase. A nine-sec delay time was
acceptable for the imaging of the canine hepatic arteries by
CT angiography. After completion of arterial phase scanning,
venous structures of the liver were well visualized as seen on
the venous phase.
