Table 1

Technical parameters for acquisition of CT images.

Parameter	Details
CT scanner detail	Images were acquired on one of the following CT scanners, all utilizing multidetector technology:
	(i) Siemens somatom definition 64-slice scanner
	(ii) Hitachi scenaria view 128-slice scanner
	(iii) General electric lightspeed VCT 64-slice scanner
Image acquisition	Isotropic imaging was utilized in all acquisitions, with 0.625 mm slices acquired, with images reviewed utilizing multiplanar reformats with a reconstructed slice thickness of 1.25 mm
Contrast tracking	Images utilized in this study were acquired in the arterial phase of contrast enhancement, utilizing bolus tracking software, with the region of interest centered over the lower thoracic (descending) aorta
Contrast phase	A single arterial phase acquisition was performed, followed by portal venous phase images
