IVUS
Pronunciation: EYE-vus
Also written as: IVUS — Intravascular Ultrasound
Intravascular ultrasound; an imaging technique using ultrasound from within blood vessels.
Full Definition
Intravascular ultrasound (IVUS) is a catheter-based imaging modality that uses ultrasound technology from within blood vessels to provide real-time, cross-sectional images of vessel walls and luminal dimensions. IVUS offers superior resolution for assessing plaque composition, vessel wall structure, and stent deployment compared to conventional angiography. The technique is particularly valuable in coronary interventions for optimizing stent placement, measuring vessel dimensions, and evaluating the results of percutaneous procedures. IVUS can also detect complications such as dissection or incomplete stent apposition that may not be visible on standard angiography.
Usage
Usage note: Commonly pronounced as a word rather than individual letters.
In Context
- "IVUS confirmed optimal stent expansion with good wall apposition." — Cardiac catheterization report
- "The vessel diameter was measured at 3.2 mm by IVUS prior to stent selection." — Interventional cardiology procedure note
