Unmatched size of prostate masks about prostatex_masks HOT 4 CLOSED

I have checked the first 2 cases (as a sample). The issue is simply that multiple axial T2 sequences are available, and the anatomical masks in these were not taken on the same images as the lesion masks. This is already reflected in the image list CSV files in each folder. These specify the correct T2 sequence to use for each mask (lesion or anatomical). I understand this is not ideal, but the two processes were conducted in separate occasions and different files were employed.
Please check you are referencing the correct image list for the mask set.

Thanks for the fast reply. I have checked the files and you are right. May I ask how to choose between the different T2 images in a single patient scan, like for zonal segmentation. Or I am confused on why there can be two similar T2s.

The sequences were repeated in the dataset for unknown reasons. For us, the choice was essentially due to chance. In some cases there might be artifacts (e.g., patient movement) that require a new acquisition of a series, but the images used for the segmentation process were all considered viable for the task at hand. In one of the papers we report the exclusion of 1 case for artifacts on the ADC map (for the purpose of lesion segmentation, T2 images were fine for gland/zonal segmentation).

Very clear. I shall check your papers. Thanks a lot.
