Vascular imaging enables the healthcare professionals to understand the blood vessels of patient's body. These painless, noninvasive, no-radiation tests can reveal plaque buildup or hardening in the arteries (atherosclerosis), blood clots, aneurysms or other abnormalities that may disturb the body blood flow and raise your risk for heart attack or stroke. Venous imaging focuses on veins, which carry blood back to the heart. Arterial imaging focuses on arteries, which carry oxygenated blood from the heart to the body's tissues.

The vascular imaging market is anticipated to grow in the forecast period owing to key factors such as increasing prevalence of cardiovascular diseases, growing minimally invasive diagnostic as well as treatment, and technological advancements in vascular imaging devices. Moreover, regulatory approvals for new and advanced vascular imaging and increasing number of diagnostic imaging centers pose growing opportunities for the growth of the global vascular imaging market.
