Prostate gland segmentation is the primary step to estimate gland volume, which aids in the prostate disease management. In this study, we present a 2D-3D convolutional neural network (CNN) ensemble ...that automatically segments the whole prostate gland along with the peripheral zone (PZ) (PPZ-SegNet) using a T2-weighted sequence (T2W) of Magnetic Resonance Imaging (MRI). The study used 4 different public data sets organized as Train #1 and Test #1 (independently derived from the same cohort), Test #2, Test #3 and Test #4. The prostate gland and the peripheral zone (PZ) anatomy were manually delineated with consensus read by a radiologist, except for Test #4 cohorts that had pre-marked glandular anatomy. A Bayesian hyperparameter optimization method was applied to construct the network model (PPZ-SegNet) with a training cohort (Train #1,
n
= 150) using a five-fold cross validation. The model evaluation was performed on an independent cohort of 283 T2W MRI prostate cases (Test #1 to #4) without any additional tuning. The data cohorts were derived from The Cancer Imaging Archives (TCIA): PROSTATEx Challenge, Prostatectomy, Repeatability studies and PROMISE12-Challenge. The segmentation performance was evaluated by computing the Dice similarity coefficient and Hausdorff distance between the estimated-deep-network identified regions and the radiologist-drawn annotations. The deep network architecture was able to segment the prostate gland anatomy with an average Dice score of 0.86 in Test #1 (
n
= 192), 0.79 in Test #2 (
n
= 26), 0.81 in Test #3 (
n
= 15), and 0.62 in Test #4 (
n
= 50). We also found the Dice coefficient improved with larger prostate volumes in 3 of the 4 test cohorts. The variation of the Dice scores from different cohorts of test images suggests the necessity of more diverse models that are inclusive of dependencies such as the gland sizes and others, which will enable us to develop a universal network for prostate and PZ segmentation.

Akazome Emon a fost o poetă apreciată. Este considerată a fi principala autoare a istoriei familiei Fujiwara (Eiga monogatari). Ea este reprezentată aici după o noapte nedormită în care şi-a asteptat ...zadarnic iubitul, îmbrăcată într-o robă albă cu reliefuri pronunţate, după cum lasă să se înţeleagă şi versurile din cartuşul lucrării: "îmi doresc sa mă fi dus imediat la culcare, dar acum noaptea a trecut şi privesc luna coborând"

Akazome Emon was an acclaimed poet. She is considered to be the main author of the history of the Fujiwara family (Eiga monogatari). She is represented here after a sleepless night in which she waited in vain for her boyfriend, dressed in a white robe with pronounced reliefs, as she leaves to understand also the lyrics from the cartridge of the work: “I wish I had gone to bed immediately, but now the night has passed and I look at the moon descending.”
