MRA is also useful to differentiate atherosclerotic PAD from other causes such as neurogenic claudication and entrapment. MRA is accurate for detecting hemodynamically significant stenoses (greater than 50%). (SOURCE: “Diagnosis and management of peripheral arterial disease…”)
Clinical uses of MRA and/or Magnetic Resonance Venography (MRV) for suspected or known vascular pathologies are well-established by research, and recognized by major insurance company policies and Medicare.
Disease Indications for Vascular MRA/MRV
MRA/MRV is considered medically necessary (standard of care) for the diagnosis and ongoing treatment of many vascular diseases, including:
- Deep Vein Thrombosis
- Peripheral Artery Disease (PAD)
- Occlusive Disease
- Arterial Dissection
- Arteria Peronea Magna
- Atherosclerosis, including atherosclerotic peripheral vascular disease
- Aortoiliac disease (“Inflow disease”)
- Femoropopliteal disease (“Outflow disease”)
- Tibioperoneal disease (“Runoff disease”)
- Congenital disorders
- Arteriovenous malformations
