DVT Ultrasound
A Deep Vein Thrombosis (DVT) Ultrasound is an ultrasound scan of the deep veins in one or both of your legs. This scan checks for deep vein thrombosis, which means blood clots in the deep veins. During the scan, the clinician applies gentle pressure to your leg to see how the veins respond. This may cause slight discomfort, but it should not be painful.
A DVT Ultrasound is a fast, safe, and reliable way to detect blood clots early. Finding a clot quickly is important because it helps your doctor plan the right treatment and reduce the risk of complications.
