RESEARCH USE

Where nnU-Net fits

Format two- or three-dimensional images with reliable pixel- or voxel-level labels as an nnU-Net dataset, then let the framework analyze the data and configure preprocessing, network, training, and inference plans. Define the split carefully so that the same subject or related images do not cross training and test sets. Preserve the dataset fingerprint, plans, software and dependency versions, logs, checkpoints, and independent test results.

Research tasks

  • Train semantic-segmentation models for biomedical images
  • Establish a reproducible U-Net segmentation baseline
  • Run batch inference with a validated model

What to evaluate before use

  • Automatic configuration does not replace careful splitting, label quality control, or external validation. Changes in scanner, institution, protocol, or population can reduce performance.
  • Segmentation output is not a clinical diagnosis, and aggregate metrics can hide errors in small structures or difficult cases. Evaluate performance by class, case, and boundary for the intended use.
