Characterization of Atypical Cystic Renal Masses With MDCT: Comparison of 5-mm Axial Images and Thin Multiplanar Reconstructed Images

Abstract

Analysis of volume data sets is associated with less intraobserver and interobserver variability than review of 5-mm axial images. Wall thickness and the number and thickness of septa may differ, resulting in assignment of different Bosniak categories. Diagnostic performance in characterizing lesions as benign or malignant, however, is not statistically different for the thick and thin images.
