Intravascular Imaging

What is intravascular imaging?

Intravascular imaging techniques give clinicians a clear look inside your blood veins and blood vessels. They help physicians more accurately diagnose cardiovascular illnesses and improve their decisions about treatment.

The most common intravascular imaging techniques are:

  • Grayscale Intravascular Ultrasound (IVUS): procedure using ultrasound to visualize potentially blocked blood veins and vessels
  • Optical Coherence Tomography (OCT): similar to ultrasound, but this procedure uses light waves instead of sound waves to create an image of the vein or vessel in question
  • Near-Infrared Spectroscopy (NIRS): a test that uses light invisible to the human eye to visualize the movement of blood in the brain
  • Fractional Flow Reserve: a catheter-based procedure that measures the severity of an artery blockage by gauging the pressure of blood flowing through the artery
