摘要：
Our objective was to compare plaque volumes of multidetector computed tomographic images reconstructed using adaptive statistical iterative reconstruction (ASIR), model-based iterative reconstruction (MBIR), and filtered back projection (FBP). We reviewed 25 patients for a total of 50 extremities imaged on the same scanner. Calcified plaque FBP volume (3468.2 +/- 2634.8 mm(3)) was higher than ASIR (2548.1 +/- 2166.5 mm(3)). Calcified plaque FBP volume was higher than MBIR (mean=2345.7 +/- 1935.4 mm(3)). Our findings suggest that traditional FBP methods overestimate disease compared to newer reconstruction methods.
