What Is Intravascular Ultrasound (IVUS)?

What is an Intravascular ultrasound study (IVUS)?

An Intravascular ultrasound study (IVUS) is where images are when high-resolution images are taken from within the artery using ultrasound.

A fine imaging probe is passed down the artery of interest.  An image is taken as the probe is withdrawn.


An alternative way of assessing the architecture of an artery wall is through Optical Coherence Tomography (OCT).
