curved planar reformation
Advanced reconstruction technique that displays vessel anatomy along a curved centerline path, allowing visualization of tortuous vessels in a single plane.
Full Definition
Curved planar reformation (CPR) is a sophisticated image reconstruction technique that creates a straightened view of curved or tortuous blood vessels by sampling image data along a manually or automatically defined vessel centerline. This technique is particularly valuable in vascular imaging for evaluating long segments of tortuous arteries, measuring vessel stenoses accurately, and assessing the longitudinal extent of vascular pathology. CPR images display the vessel lumen and wall in a single plane, eliminating the need to scroll through multiple axial images to follow vessel courses. The technique requires careful centerline definition to avoid artifacts and ensure accurate representation of vessel morphology.
Usage
Usage note: Commonly abbreviated as CPR; ensure centerline accuracy is documented.
