Pilot Study of Model Based Iterative Reconstruction Using 64-Slice Multidetector-Row CT Datasets Obtained From the Central Nervous System, Thorax, and Abdomen

This study is being performed to confirm that the new technique, Model-Based Iterative
Reconstruction (MBIR) with reduced radiation dose can deliver equivalent image quality for
CT scans compared to current techniques (Filtered Back Projection with Adaptive Statistical
Iterative Reconstruction (FBP with ASiR) and also to demonstrate that MBIR can improve
general image quality characteristics at equivalent radiation dose levels.
