Non-Invasive Vascular Testing

There are two ways to diagnose vascular disorders, invasive and non-invasive.


Invasive means putting foreign objects inside an artery to see the status of blood flow in an artery, with the most common procedure done being angiography where they insert a catheter in the leg arteries and inject a dye (hence it is sometimes called the dye test) into the arteries to see if a blockage is present.


Non-invasive testing involves either electrically monitoring the heart with or without exercise or placing an external sensor over an artery and estimating the blood flow in that artery. At the Clinic, we do 6 basic types of non-invasive testing namely Treadmill Stress Testing, vessel testing of the lower legs, Doppler studies of the neck arteries, Electrocardiogram, 24 Hour Holter Monitoring, and Electrocardiography.
