Key Points

The aim is to assess the technical advancements and clinical implications of photon-counting CT angiography for diagnosing peripheral artery disease.
Conducted a narrative review of peer-reviewed literature and scientific presentations.
Searched databases including MEDLINE, Scopus, and Google Scholar.
Included studies on image quality, diagnostic accuracy, and clinical applications of photon-counting CT in PAD.
PCCTA improves spatial resolution and reduces artifacts like calcium blooming.
Sensitivity, specificity, and accuracy in stenosis grading reach approximately 96%, 97%, and 97%, respectively.
Enhanced imaging quality assists in visualizing small, calcified, and stented vessels, surpassing conventional methods.
