3T MRI, short for Magnetic Resonance Imaging, is a radiation-free scanning technique that uses radio waves and magnetic fields to produce detailed three-dimensional images of the body. The MRI venography is an imaging test that is used to visualize veins in the body. It is used to assess blood flow in the veins and can detect blood clots or other abnormalities. By imaging blood flow, the images helps your doctor to detect, diagnose and treat blood vessel disorders and diseases such as stroke, aneurysms, clots, obstructions, and vascular disease.
