Overview

IVUS provides cross sectional images of vessel lumen and wall from within the artery guiding stent sizing and plaque assessment.

Technique

Rotational or phased array catheters produce high resolution intraluminal images. Pullback speed and calibration affect measurements.

Clinical Uses

Coronary and peripheral artery interventions for stent optimization and plaque characterization.

Limitations and Safety

Invasive with catheter related risks. Interpretation requires interventional expertise.
