vessel reformation
Post-processing technique that creates curved planar images following the course of tortuous vessels.
Full Definition
Vessel reformation is an advanced post-processing technique used in cross-sectional imaging, particularly CT and MR angiography, where curved planar reformatted images are created that follow the natural course of tortuous blood vessels. This technique allows visualization of the entire vessel length in a single image plane, even when the vessel follows a complex three-dimensional path. Vessel reformation is particularly valuable for assessing long-segment stenoses, measuring vessel lengths for stent planning, and evaluating tortuous vessels that would be difficult to assess in standard orthogonal planes. The technique requires careful selection of centerline points and appropriate thickness settings to optimize image quality.
Usage
Usage note: Often abbreviated as CPR (curved planar reformation) in technical contexts.
