Repeatability of T2W-MRI radiomic features is important to develop
consistent imaging biomarkers and evaluate prostate cancer. This study
visualizes that repeatability of radiomic features varies based on anatomical
zones and lesions, pre-processing, and feature itself.
Heatmaps of ICCs in (a) WP and (b) L datasets with selected good features
(ICC ≥ 0.75) explain the patterns of repeatability in different prostate regions and lesions relative to pre-processing configurations and radiomic features.
The highest repeatability results on each prostate regions and lesions based on radiomic feature groups based
on the and pre-processing configurations.
