IVUS
Pronunciation: EYE-vus
Also written as: IVUS — intravascular ultrasound
Intravascular ultrasound; catheter-based imaging technique providing cross-sectional views of vessel walls and lumen.
Full Definition
Intravascular ultrasound (IVUS) is a catheter-based imaging modality that uses high-frequency ultrasound to provide real-time, cross-sectional images of blood vessel walls and lumens from inside the vessel. IVUS enables precise measurement of vessel dimensions, assessment of plaque morphology and distribution, optimization of stent sizing and deployment, and detection of complications such as dissection or stent malapposition. The technology has become increasingly important for guidance of complex interventional procedures.
Usage
Usage note: Pronounced as a word (EYE-vus), not spelled out letter by letter.
