Computed Tomographic Angiography of the Abdominal Aorta and Iliac Arteries

ByEric E Walser

Technical developments in computed tomography allow fast

acquisition of vascular images since the scan time can now be

completed during the arterial transit time of a bolus intra-

venous administration of contrast. The newer, 16 and 64-slice

CT scanners have essentially replaced diagnostic angiography

for the large and medium sized vessels. This chapter reviews

imaging of the abdominal aorta and iliac arteries by multi-

detector CT (MDCT). This shift in imaging modalities is of

great interest to both the physician and the patient, as it allows

outpatient imaging of the heart and the vessels with much

decreased risk as compared to standard angiography.
