Lower extremity arterial disease (LEAD) is often associated with serious comorbidities that significantly reduce both quality of life and life expectancy. Early detection and treatment are therefore essential to reduce cardiovascular mortality. Treatment options for LEAD include conservative therapy, endovascular interventions, and open surgical procedures. According to the 2017 ESC guidelines, endovascular therapy for stenosis or occlusion of the iliac system measuring less than 5 cm provides good long-term revascularization outcomes with low complication rates; and in the femoro-popliteal region, endovascular treatment is recommended for lesions shorter than 25 cm. Regular follow-up of patients after stent implantation is critical. Given that nearly half of LEAD patients also suffer from renal impairment, the use of nephroprotective imaging modalities may be important during follow-up. One such alternative is non-contrast quiescent-interval single-shot MR angiography (QISS MRA). Read how the type and location of different arterial stents implanted in the iliac and femoro-popliteal regions affect the image quality of QISS MRA scans.
