IVUS
Pronunciation: EYE-vuss
Also written as: IVUS — Intravascular Ultrasound
Acronym for intravascular ultrasound, an imaging technique providing real-time cross-sectional views of coronary arteries.
Full Definition
Intravascular ultrasound (IVUS) is an imaging modality that uses a miniaturized ultrasound probe delivered via catheter to provide detailed cross-sectional images of coronary artery walls. The technique allows assessment of plaque composition, vessel dimensions, and stent deployment quality. IVUS guidance during percutaneous interventions has been shown to improve procedural outcomes and reduce adverse events. The technology is particularly valuable for complex lesions where angiographic assessment alone may be insufficient.
Usage
Usage note: Always capitalize when used as acronym; lowercase when spelled out as intravascular ultrasound.
In Context
- "The procedural report indicated that IVUS guidance was used to optimize stent expansion." — Procedural report
- "IVUS imaging revealed significant plaque burden despite angiographically normal appearance." — Clinical documentation
