How are BRATS sequences used? #69

Closed joseph-bae closed 2 months ago

joseph-bae commented 5 months ago

Hello,

I was wondering whether each individual sequence from BRATS 21 (T1, T1w, T2, FLAIR) was treated as a separate sample or if all sequences were combined into a 4 channel input. If the latter, how was this input into the one channel input network? If the former, how were evaluation metrics calculated for BRATS?

Thank you

It is treated as separate 4 samples to fit the single-modal input. Our reported performance on BraTS is computed by averaging the 4 single-modal results. It is more challenging than the original setting of BraTS.
