Manual prostate cancer segmentation in MRI: interreader agreement and volumetric correlation with transperineal template core needle biopsy

ConclusionsWe found at best moderate interreader agreement of manual prostate cancer segmentation in mpMRI. Additionally, our study suggests a systematic discrepancy between the tumor volume estimate by MRI segmentation and TTSB core length, especially for large and high-grade tumors.Key Points• Manual prostate cancer segmentation in mpMRI shows moderate interreader agreement.• There are no significant differences between T2, ADC, and DCE segmentation agreements.• There is a systematic difference between volume estimates derived from biopsy and MRI.
