Prostate segmentation by Guerbet
About
- Transverse T2 Prostate MRI (Transverse T2 MRI of the Prostate)
- Transverse HBV Prostate MRI (Transverse High B-Value Prostate MRI)
- Transverse ADC Prostate MRI (Transverse Apparent Diffusion Coefficient Prostate MRI)
- Transverse Prostate Segmentation MRI (Segmentation of a transverse MRI which isolates the whole prostate gland. Value 1 is the prostate gland.)
Model Facts
Summary
This model is based on nnU-Net for segmenting the prostate gland. The algorithm was trained on the PI-CAI dataset of 1500 patients, on a 5-fold cross-validation manner. It was trained by Guerbet IA team as part of their participation in the PI-CAI challenge.
Mechanism
Input:
-
Data type: axial T2w MRI, DWI with high b-value MRI, and ADC map.
-
File format: NIfTI or MHA format, containing pixel spacing information.
-
Target population: Men without prostactomy or resection.
Output: - Binary mask of the segmented prostate gland.
Model type: Baseline nnU-Net was trained with 5-fold cross-validation. Fold splits were given by the PI-CAI challenge.
Validation and Performance
On cross-validation dataset, nnU-Net performing prostate gland segmentation showed a mean overall 3D patient level dice of:
| Fold | 3D Dice |
|---|---|
| Fold 0 | 0.968 |
| Fold 1 | 0.968 |
| Fold 2 | 0.972 |
| Fold 3 | 0.966 |
| Fold 4 | 0.970 |
Uses and Directions
This algorithm was developed for research purposes only.
