Diagnostic limitations in advanced stage peripheral arterial disease in a cadaveric study comparing photon-counting and energy-integrating CT detectors

CT angiography (CTA) is widely accepted as the standard diagnostic modality for evaluating PAD, particularly in the femoral runoff. However, the efficacy of CTA in advanced PAD stages is often compromised by severe arterial calcification and the presence of stents, which can obscure the vascular lumen and this has noteworthy impact on the decision for endovascular therapy versus bypass surgery, particularly in complex cases.
