intravascular ultrasound
Catheter-based ultrasound imaging technique that provides cross-sectional views of blood vessel walls from within the vessel lumen.
Full Definition
Intravascular ultrasound (IVUS) is an invasive imaging modality that uses a miniature ultrasound transducer mounted on a catheter to obtain real-time, high-resolution cross-sectional images of blood vessels from the inside. This technique provides detailed information about vessel wall structure, plaque composition, and luminal dimensions that may not be apparent on conventional angiography. IVUS is particularly valuable in guiding interventional procedures, assessing stent deployment, and evaluating the success of revascularization procedures.
Usage
Usage note: Commonly abbreviated as IVUS in clinical documentation.
