The aim of this clinical study is to 1) establish a healthy database for nuclear perfusion imaging of the lower extremities and 2) assess the prognostic value of radiotracer-based perfusion imaging for predicting clinical outcomes in patients with peripheral artery disease (PAD) who are undergoing lower extremity revascularization procedures. We hypothesize that radiotracer imaging of the lower extremities will provide a sensitive non-invasive imaging tool for quantifying regional abnormalities in skeletal muscle perfusion and evaluating responses to medical treatment.
