Radiotracer Imaging of Skeletal Muscle Perfusion in Patients With Peripheral Artery Disease
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.
• At least 18 years of age
• Evidence of significant obstructive disease for one or multiple lower extremity arteries, as identified by prior ABI, TBI, CT angiography, ultrasound, or MR imaging.
• At least 18 years of age
• No evidence or prior diagnosis of peripheral artery disease based on chart review and standard vascular screening.
