Whole-Organ CT Perfusion of the Pancreas: Impact of Iterative Reconstruction on Image Quality Perfusion Parameters and Radiation Dose in 256-Slice CT-Preliminary Findings

摘要

BackgroundThis study was performed to assess whether iterative reconstruction can reduce radiation dose while maintaining acceptable image quality, and to investigate whether perfusion parameters vary from conventional filtered back projection (FBP) at the low-tube-voltage (80-kVp) during whole-pancreas perfusion examination using a 256-slice CT.
