| Abstract | Introduction: Recently, computed tomographic angiography (CTA) has become widely used for lower extremity arterial runoff imaging, in part because of high spatial resolution and extended coverage obtained with continuous table movement during the exam. However, even with optimized technique, 2-3% of studies are nondiagnostic because of calcification, poor contrast opacification, or venous contamination [1]. Recently, our group described high-spatial-resolution (1-mm isotropic) time-resolved 3D contrast material-enhanced magnetic resonance angiography (MRA) of the peripheral vasculature with Cartesian acquisition with projection-reconstruction-like sampling (CAPR) and 8x two-dimensional (2D) sensitivity encoding (SENSE) [2]. We sought to compare image quality and characteristics in patients who had undergone both CTA and CAPR runoff studies of the lower extremities. |
