Table 4 Values obtained in PG, CZ and PZ regions of interest using ground truth and predicted masks. “mask” and “predicted” in the column headers refer to the ground truth and model output, respectively. T-test results between ground truth and predicted masks for PG, CZ, and PZ are reported in the right part of the table (based on segmentation results for the IMs using magnitude images as input).
