VASCULAR MRI
Vascular MRI, also known as Magnetic Resonance Angiography (MRA) or Venography (MRV), is a specialized MRI study used to evaluate the blood vessels — arteries and veins — in various parts of the body. When performed for the limbs, it provides clear, non-invasive imaging of the vascular system in the upper or lower extremities, helping detect blockages, narrowing (stenosis), aneurysms, clots (thrombosis), or vascular malformations.
An Upper Extremity Vascular MRI focuses on the arteries and veins in the shoulders, arms, forearms, and hands. It is particularly useful in identifying vascular compression (such as in thoracic outlet syndrome), arterial narrowing, blood flow issues following trauma, or evaluation of dialysis access in patients with fistulas or grafts. It can also be used to assess unexplained arm swelling or pain related to venous thrombosis.
Similarly, Lower Extremity Vascular MRI is commonly performed to assess the blood supply to the thighs, knees, legs, and feet. It plays a crucial role in diagnosing peripheral artery disease (PAD), deep vein thrombosis (DVT), post-surgical complications, and vascular insufficiency in diabetic patients. This type of scan is often indicated for patients with leg pain while walking, non-healing ulcers, cold extremities, or suspected vascular blockages.
These studies are typically performed with contrast to highlight blood vessels more clearly, though non-contrast techniques may be used when contrast is contraindicated. Vascular MRI offers a safe, accurate, and detailed evaluation of limb circulation without the need for catheter-based procedures or radiation exposure, making it a preferred choice for both initial diagnosis and follow-up imaging in vascular conditions.
