calcific plaque
Atherosclerotic plaque containing calcium deposits that appear as high-density areas on CT imaging.
Full Definition
Calcific plaque refers to atherosclerotic deposits within vessel walls that contain calcium salts, appearing as bright, high-attenuation areas on CT scans and as acoustic shadows on ultrasound. These calcifications represent chronic atherosclerotic changes and can significantly impact treatment planning, particularly for endovascular interventions. Calcific plaques may be circumferential or eccentric and can cause vessel stiffness and procedural complications. In radiological reporting, the distribution, extent, and morphology of calcific plaque must be accurately described to guide clinical management.
Usage
Usage note: Distinguish from soft plaque and specify distribution pattern.
