T2 ROI measurements on tumor and non-tumor regions in thirty-eight PCa patients (group 1).

DL, deep learning.

Two series of paired t-tests were included in the analysis: one is between deep learning estimation and ground truth (only on Group 1a), and the other is between tumor and non-tumor regions with the significance level of *P < 0.05; ***P < 0.001.
