CT reconstruction algorithms affect histogram and texture analysis: evidence for liver parenchyma, focal solid liver lesions, and renal cysts
The aim of this study was to determine the effects of different reconstruction algorithms on histogram and texture features in different targets. The authors reconstructed CT images with filtered back-projection (FBP), hybrid iterative reconstruction (HIR), and iterative model reconstruction (IMR) algorithms and performed computerized histogram and texture analyses by extracting 11 features. The results enabled the authors to conclude that
