ABSTRACT
The last decade has witnessed an exciting and at times
breathtaking evolution in cross-sectional imaging. The
lightning pace of change in MRI and CT has completely
revolutionized the way we as practicing radiologists and our
referring clinician colleagues evaluate patients for a wide
array of pathologies. Multidetector CT has transformed CT
imaging from a two-dimensional into a powerful three-
dimensional imaging modality. This evolution has brought
to the mainstream single breath-hold imaging of the
abdomen and pelvis, with sub-millimeter isotropic acquisi-
tions. This change is particularly evident in the field of CT
angiography, where the advances in CT technology now
allow us to detect subtle changes in second and third order
segmental branches in the mesenteric and renal vasculature.
The recent advances allow CT angiography not only to rival,
but in many cases to replace, diagnostic digital subtraction
