Given the limitations of CTA in evaluating heavily calcified vessels, we aimed to determine whether quiescent-interval single-shot (QISS) MRA provides better diagnostic agreement with digital subtraction angiography (DSA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and methods<\/jats:title>\n                    <jats:p>In this retrospective study, 25 patients who underwent lower limb QISS MRA between April 2022 and April 2024 were included.
