Improvement in contrast and image quality with the use of low-energy virtual monoenergetic imaging (VMI+) reconstructions on contrast-enhanced dual-energy CT angiography of the lower extremities in diabetic patients with peripheral arterial disease

    A retrospective study evaluated the impact of a virtual monoenergetic imaging (VMI+) algorithm applied to contrast-enhanced dual-energy CT (DECT) angiography of the lower extremities in diabetic patients, in order to obtain a qualitative improvement of images of the vascular structures. Low-keV (40 to 55 keV) VMI+ DECT reconstructions provide the highest contrast and greatest image quality improvement compared to other VMI+ energy levels and conventional images.
