curved planar reformation
Also written as: CPR — Curved Planar Reformation
Post-processing technique that straightens curved vessels to display their entire length in a single plane.
Full Definition
Curved planar reformation (CPR) is a specialized image reconstruction technique used to evaluate tortuous or curved arteries by digitally straightening them into a single planar view. This method is particularly useful for assessing stenosis severity along the entire vessel length without the overlap that occurs in traditional angiographic projections. CPR is commonly applied to coronary arteries, carotid vessels, and peripheral arteries where tortuosity might obscure pathology. The technique preserves luminal measurements while providing an unobstructed view of vessel morphology.
Usage
Usage note: Distinguish from cardiopulmonary resuscitation (CPR) - context usually clarifies meaning.
