1 Adequacy of an early arterial phase low-volume contrast protocol in 64-detector computed tomography angiography for aortoiliac aneurysms  Nicolas Diehm, MD, Constantino Pena, MD, James F. Benenati, MD, Athanassios I. Tsoukas, MD, Barry T. Katzen, MD  Journal of Vascular Surgery  Volume 47, Issue 3, Pages (March 2008) DOI: /j.jvs Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Representative 64-detector computed tomography image with 100 mL of contrast medium in a 72-year-old man with a 55-mm abdominal aortic aneurysm. A, Transverse image shows the infrarenal aortic aneurysm at its widest transverse diameter. Arterial attenuation, HU. B, Sagittal reconstruction shows the infrarenal aorta and common iliac artery with adequate arterial enhancement along the aortoiliac segment.

3 Fig 2 Representative 64-detector computed tomography image using 50 mL of contrast medium in an 82-year-old woman with a 48-mm abdominal aortic aneurysm. A, Transverse image shows the infrarenal aortic aneurysm at its widest transverse diameter. Arterial attenuation, HU. B, A reconstructed sagittal view shows the infrarenal aorta and common iliac artery with adequate arterial enhancement along the aortoiliac segment.

4 Fig 3 Mean attenuation ± SD along the aortoiliac z-axis for group A, which received 50 mL of contrast material (circle, solid line), and for group B, which received 100 mL of contrast material (square, dotted line). The graph shows constant arterial enhancement along the aortoiliac z-axis for both protocols (P > .05). ROI, Region of interest.
