1. To review the indications of ultrasound (USG) in peripheral arterial diseases 2. To review the normal and abnormal flow patterns in peripheral arteries 3. To illustrate imaging appearances of common peripheral arterial abnormalities.

1. INTRODUCTION 2. ANATOMY 3. ROLE, ADVANTAGES, LIMITATIONS OF USG- Comparison with other invasive and non-invasive modalities 4. TECHNICAL REQUIREMENTS-B-mode, doppler, color, power 5. OPTIMIZATION OF TECHNICAL PARAMETERS 6. TRANSDUCER AND PATIENT POSITION 6. NORMAL VESSEL- Normal caliber, laminar flow 7. WAVEFORMS - Normal - Triphasic or biphasic with sharp systolic upstroke; -Abnormal - Monophasic or biphasic without sharp systolic upstroke 8. VELOCITIES- Normal and abnormal at, proximal and distal to stenosis; grading of stenosis 9. ILLUSTRATION OF THE FOLLOWING ABNORMALITIES WITH SAMPLE CASES A. Atherosclerosis, native vessels- Indications; Diagnostic approach; Screening localization; Criteria for different grades of stenosis- Velocities, waveforms, pre and post stenotic vessels; Collaterals; Pitfalls, misses B. Bypass graft evaluation C. Stent evaluation D. Aneurysms E. Pseudoaneurysms- To-and-fro flow, guidance for management F. Popliteal artery entrapment G. Dissection H. Arteritis I. AV Fistula- High-velocity turbulent flow between vessels; low resistance proximal arterial waveforms; High, arterialized venous flow; vibration artifacts in perivascular tissues. J. Post-surgical/interventional follow-up- Grafts, thrombin injection
