Because the diagnostic criteria for prostate cancer are different in the peripheral and the transition zone, prostate segmentation is needed for any computer-aided diagnosis system aimed at characterizing prostate lesions on magnetic resonance (MR) images. Manual segmentation is time consuming and may differ between radiologists with different expertise. We developed and trained a convolutional neural network algorithm for segmenting the whole prostate, the transition zone and the anterior fibromuscular stroma on T2-weighted images of 787 MRIs from an existing prospective radiological pathological correlation database containing prostate MRI of patients treated by prostatectomy between 2008 and 2014 (CLARA-P database).
The purpose of this study is to validate this algorithm on an independent cohort of patients.

Benign Prostatic Hyperplasia (BPH)
An enlarged prostate (benign prostatic enlargement (BPE) or benign prostatic hyperplasia (BPH)) is common in men after the age of about 50. Having an enlarged prostate does not mean you have cancer. In some cases, an enlarged prostate can cause the ...
