Automatic plaque removal by dual energy CTA: assessment of effectiveness and impact on quantification of stenosis – a phantom study
 |
The following abstract was presented during the 89th German Congress of Roentgenology in Berlin (May 2008, 20th – 23th) Purpose: Dual energy CT allows automatic removal of calcified plaques from vessel lumen based on different absorption properties of calcium and iodine. The purpose of this phantom study was to evaluate the … Read more
