If your provider suspects vascular disease, they may order non-invasive (no needles) vascular testing. This type of imaging involves various tests that measure blood flow in your arteries and veins. Registered Vascular Technologists (RVTs) receive special training to perform these studies. They use high-frequency sound waves (ultrasound) to determine the presence, location and severity of vascular disease.
Vascular testing:
- Ankle-brachial index (ABI)
- Ankle-brachial index (ABI) with exercise (treadmill)
- Aortoiliac duplex
- Aortoiliac duplex for abdominal aortic aneurysm (AAA)
- Arterial duplex-lower extremity
- Arterial duplex-upper extremity
- Arteriovenous (AV) fistula duplex
- Bypass graft duplex
- Carotid duplex
- Deep vein thrombosis (DVT)
- Mesenteric/celiac/renal artery stenosis
- Pulse volume recordings (PVRs)
- Segmental Pressures
- Venous reflux (insufficiency)
- Venous mapping
