Description

Segmentations of the prostatic zones and urethra for 200 patients from the publicly available PROSTATEx image dataset [1-3]. The dataset is intended for research purposes in the field of medical imaging and to enable training and evaluation of automatic segmentation methods.

The prostatic zones and urethra were manually segmented slice by slice on axial T2w MRIs by two experienced radiologists in collaboration with three junior colleagues. All delineations by junior colleagues have been checked, and if necessary, corrected by one of the more experienced radiologists. The two most experienced radiologists have independently delineated duplicate segmentations for 40 patients, for a total of 240 segmentations. This is intended as a test set where automatic methods can compare their performance with the inter-reader variability of the two radiologists.

To ease the use of the dataset, help with structuring the data can be found in the linked GitHub repository.
