Vascular Imaging

Service Description

Vascular studies include a subset of ultrasound studies that look specifically at the blood vessels. Like any other ultrasound, we use a probe on top of the skin to emit and receive sound waves, with Doppler shifts (just like a radar speed gun) to follow blood flow. This allows us to non-invasively investigate most of the arteries and veins in the body, including:

  • Transcranial Doppler (TCD) to evaluated the arteries inside the head
  • Carotid Ultrasound to look at the arteries of the neck
  • Mesenteric Ultrasound to look at the arteries to the bowel
  • Renal Ultrasound to look at the arteries to the kidneys
  • Aorta Ultrasound to check for an aneurysm of the abdominal aorta
  • Duplex Extremity Ultrasound to look at the arteries, veins or grafts of the arms/legs
  • Venous mapping prior to fistula placement for dialysis or graft harvesting for cardiac surgery
    • In addition, we also perform a variety of screening studies that don't even need ultrasound. We can often screen for arterial disease with blood pressure cuffs and pulse wave assessment. These studies include:

      • Ankle-Brachial Indices, at rest and with stress
      • Segmental Pressures to look for peripheral arterial disease
      • Digital photoplethysmography to evaluate the small arteries of hand and toes
      • Tissue Perfusion Pressure to evaluate wounds for healing potential

      None of these medical tests require an IV or any contrast and you will not be exposed to any radiation. However, please follow any specific recommendations before your test as some of these do require you to fast for several hours beforehand.
