Category of renal cyst location and the effect of high attenuation material in Z-direction on x-ray scatter X-ray scatter is part of the reason for pseudo enhancement. 2D snit-scatter grid is an essential technology as countermeasure of pseudo enhancement on MDCT.

Impact of scattered x-ray on image quality X-ray scatter fundamentals and its effect on CT Hounsfield unit measurement  Phantom setup to observe irregularity CT Hounsfield unit on X-ray scatter The phantom design of simulating simple cyst in enhancement/ non-enhancement renal Approaches of scatter correction Influence with longitudinal coverage of CT scanners Comparison of shifted CT Hounsfield unit by the location of high attenuation material Comparison of 2D anti-scatter grid and 1D anti-scatter grid Clinical impact of pseudo enhancement Statically analysis of the shift in Hounsfield unit measurements on the renal cyst location Statically analysis of the shift in Hounsfield unit measurements in 600 clinical cases of different CT scanner (Aquilion CXL; Toshiba Medical Systems, Brilliance iCT; Philips Healthcare)
