Non-Invasive Vascular Studies
Ultrasounds are the most frequently used non-invasive vascular study, as these types of tests are capable of delivering imaging of the heart – including the direction and pace of blood flow. Physicians also order segmental pressure tests and pulse volume recordings to localize blockages in the body’s extremities. During these tests, blood pressure cuffs are simultaneously placed in multiple places on each limb of the body. The test will reveal inadequate pulse volume and its source. |
After conducting physical exams of their patients, physicians use
non-invasive vascular studies as the starting point for diagnosing
diseases and conditions that affect the circulatory system, such as
atherosclerosis, aneurysms and deep vein thrombosis. These tests are
considered non-invasive because they do not require the use of needles
or injection of dyes. Examples include chest x-rays, electrocardiograms
and CT scans.
