Please star this repository if you like it :)

Feel free to leave feedbacks and ask questions. We want to make the repository helpful for your research.

We will keep updating this repository for pretrained models and weights.

UKBiobank_deep_pretrain

Pretrained neural networks for UK Biobank brain MRI images. SFCN, 3D-ResNet etc.

Under construction.

The models are trained, validated and benchmarked with UK Biobank brain MRI images, 14,503-subject release.

Model input shape: [batch_size, 1, 160, 192, 160]

Pretrained weights (no subject level information)

File Model No. training subjects Test MAE (years) Validation MAE (yrs) Train MAE (yrs) Val-Train MAE gap (yrs)
./brain_age/run_20190719_00_epoch_best_mae.p SFCN (SGD) 12,949 2.14±0.05 2.18±0.04 1.36±0.03 0.83±0.06

(As summarized in Table 1 in the manuscript)

Examples

Checkout the file examples.ipynb

model = SFCN()
model = torch.nn.DataParallel(model)
# This is to be modified with the path of saved weights
p_ = './run_20190719_00_epoch_best_mae.p'
model.load_state_dict(torch.load(p_))
