Example case in axial and sagittal view with corresponding zone segmentation. The 4-class segmentation consists of peripheral zone (pink), transitional zone (yellow), anterior fibromuscular stroma (blue)  and distal prostatic urethra (brown)

This collection contains prostate’s zonal segmentation for 98 cases randomly selected from the SPIE-AAPM-NCI PROSTATEx Challenges. The four-class segmentation encompasses the peripheral zone, transition zone, fibromuscular stroma and the distal prostatic urethra. As underlying images, we used transversal T2w scans. Segmentations were created by a medical student with experience in prostate segmentation and an expert urologist who instructed the student and double-checked the segmentations in the end. The DICOM representation of these segmentations were generated with dcmqi.
