SPECT/CT Imaging of Skeletal Muscle Perfusion

Summary

This study will use SPECT/CT imaging to assess the effect of percutaneous revascularization treatments in patients with Peripheral arterial disease and diabetes mellitus, in whom the disease can progress more quickly than in patients without diabetes.

Eligibility

Inclusion Criteria for Healthy Control Population:

1. At least 18 years of age
2. Normal (0.9-1.2) Ankle Brachial Index

Inclusion Criteria for patients undergoing clinically indicated myocardial perfusion study:

1\) At least 18 years of age 2) scheduled for stress myocardial perfusion imaging study for clinically indicated reason

-Inclusion Criteria for PAD Patient Population:

1. At least 18 years of age
2. Evidence of significant obstructive disease for one or multiple lower extremity arteries, as identified by CT angiography, ultrasound, or MR imaging or an abnormal ankle-brachial index or toe-brachial index
3. Previously diagnosed diabetes mellitus (type I or II), based on any of the following criteria: fasting plasma glucose great than 126 mg/dl on 2 separate occasions, glycated hemoglobin (HbA1c) greater than 6.5% on 2 separate occasions, fasting plasma glucose greater than 200 mg/dl 2 hours following an oral glucose tolerance test on 2 separate occasions, or fasting plasma glucose and HbA1c above normal limits on same visit.
4. scheduled for revascularization due to obstructive blood flow in the lower extremities.
