IVUS-VH
Also written as: IVUS-VH — Intravascular Ultrasound with Virtual Histology
Intravascular ultrasound with virtual histology technology that provides color-coded tissue characterization of coronary plaque components.
Full Definition
Intravascular ultrasound with virtual histology (IVUS-VH) is an advanced imaging modality that combines traditional IVUS with radiofrequency data analysis to create color-coded maps of plaque composition. The technology distinguishes between fibrous tissue (green), fibrofatty tissue (light green), necrotic core (red), and dense calcium (white). This detailed tissue characterization helps interventional cardiologists assess plaque vulnerability and optimize treatment strategies. IVUS-VH is particularly valuable in research settings and complex interventional procedures where understanding plaque morphology is critical.
Usage
Usage note: Always hyphenate when used as an adjective; capitalize all letters in the acronym.
