Noninvasive Diagnostic Studies

Our physicians perform non-invasive studies such as:  

  • Carotid duplex
  • Abi’s (ankle brachial indicies) with digit pressures
  • Upper and lower extremity arterial duplex
  • Upper and lower extremity venous duplex with reflux exam
  • PAP’s/PVR ‘s (segmental and digital plethysmography and pulse volume recordings)
  • Bypass graft surveillance
  • Aortoiliac ultrasound
  • Renal and mesenteric artery ultrasound
  • Hemodialysis access ultrasound evaluation

After a physician’s physical examination, testing in a vascular laboratory is often the first step in diagnosing vascular disease. Specific tests that will be done will depend on the patient’s symptoms and the suspected vascular problems. Diagnosing vascular disease begins by taking a careful medical history, including risk factors and a  physical exam (including symptoms, temperature of the skin, appearance of limbs and blood vessels, and presence or absence of pulses). From this information, the physician decides if further testing is needed.  Non-invasive testing utilizes various types of technology to evaluate flow, perfusion and pressures within the vessels at rest and with exercise. These procedures are generally painless and can help to determine if blood vessel disease is present, the location, and severity. From the results of these tests, the physician will determine the need for more non-invasive testing or procedures to treat vascular disease.
