The purpose of this exhibit is: 1. Review all arteries outside of the brain that can be evaluated with Doppler ultrasound.  2. Learn imaging criteria for diagnosing significant stenosis in each artery. 3. Learn primary and secondary signs of arterial stenosis.  

General principles 1. Waveform appearance within and adjacent to a significant stenosis 2. Optimizing color and spectral Doppler Head & neck arteries 1. Internal carotid- non-operated, post CEA, and post stenting 2. Common and external carotid 3. Subclavian- with TOS evaluation 4. Vertebral 5. Innominate Abdomen arteries 1. Abdominal aorta 2. Celiac- with MALC evaluation 3. SMA, IMA 4. Renal- native and transplant renal artery evaluation 5. Iliac Upper extremity arteries 1. Axillary, brachial, ulnar 2. Radial- with evaluation for radial artery dependence Lower extremity arteries 1. CFA, SFA, DFA, popliteal 2. PTA, ATA, peroneal 3. Bypass grafts, stents The major teaching points of this exhibit are: 1. There are general principles to know when evaluating arteries for stenosis within and proximal and distal to the stenosis. Adhering to them improves diagnostic accuracy. 2. Several arteries have unique imaging criteria when diagnosing stenosis. 3. In some arteries maneuvers can be performed to diagnose a stenosis.
