Dataset No. 10

Male Pelvis Prostate Cancer MR (PI-RADS 4, 5) with Segmentation and Classification

Notes

This prostate MRI dataset is rigorously de-identified and largely excludes cases with complications, excessive noise, prior surgery, or recurrence. However, to reflect real-world clinical heterogeneity, it does include some cases with concurrent primary malignancies, such as bladder, rectal, or penile cancer. All cases include T1w, T2w, DWI, and ADC images, and DCE images if available, from subjects with prostate cancer. Radiologic technologists performed the initial lesion segmentations, which were subsequently reviewed and corrected by radiologists, with difficult cases undergoing an additional radiologist review. The dataset includes segmentation masks for all lesions assessed as PI-RADS 4 or 5, together with prostate-related radiology reports. The segmentations include extracapsular extension within the contours while excluding skeletal metastases. Since they are based on clinical practice, some clinical information and sequences may not be available.
