Radiotracer-Based Perfusion Imaging of Patients With Peripheral Arterial Disease

Summary

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.

Eligibility

Inclusion Criteria for Patients with Peripheral Artery Disease:

1. Unable to give informed consent or follow-up
2. Pregnant or nursing
3. Under the age of 18
4. No history of peripheral artery disease

Inclusion Criteria for Healthy Control Subjects:

1. At least 18 years of age
