EURO-PROBE - Maunal segmentations of the prostate and intraprostatic urethra on T2-weighted MRI

The EURO-PROBE dataset provides manually created segmentations of the prostate and intraprostatic urethra on axial T2-weighted MRI volumes, complementing the existing LUND-PROBE (LUND Prostate Radiotherapy Open Benchmarking and Evaluation) dataset for prostate radiotherapy research. Delineations were performed by delineators with varying levels of experience, including radiologists, radiology and urology residents, and medical students, which enables both inter-reader variability analysis and stratification by reader experience. Across all 467 cases of the LUND-PROBE dataset, the delineation process resulted in 1227 segmentations consisting of two structures each. By expanding the LUND-PROBE dataset, EURO-PROBE supports the development of automated segmentation tools, including for the urethra, which is a highly relevant organ at risk in focal dose escalated prostate radiotherapy. Code examples for how to load and visualize the data can be found in the GitHub repository. For more information about the dataset, see the dataset publication: ... in PEIR-REVIEW ...
