The complexity
of the prostatic tissue requires sensitive, accurate and reproducible
assessment methods for aggressiveness of prostatic carcinomas, especially in differentiating
between Gleason score 3+4 and 4+3 tumors. We evaluated the applicability of T2W
MRI-derived textural entropy as a potential marker for assessing prostate cancer
aggressiveness. Our study found textural entropy to correlate moderately positive and negative with Gleason score and apparent diffusion coefficient (ADC),
respectively. T2W image textural entropy differentiated Gleason score 3+4 and
4+3 tumors with higher accuracy than other MRI-derived parameters (ADC, Ktrans
and Ve), indicating the potential of MRI texture analysis in
prostate cancer assessment.
