    Summary

    This algorithm is one of the two baseline algorithms of the SPIDER-Challenge.

    The SPIDER Challenge focuses on the segmentation of three anatomical structures in lumbar spine MRI: vertebrae, intervertebral discs (IVDs), and spinal canal. The segmentation task requires similar algorithms to produce separate masks for each vertebra, IVD, and the spinal canal in the lumbar spine MRI volume. This is an nnU-Net based algorithm trained on the complete SPIDER training and validation set using five-fold cross-validation. The labeling sequence of the SPIDER dataset was altered before training this algorithm. The spinal canal is labeled as 1. All IVDs and vertebrae are labeled between 2 and 49 from caudal to cranial (e.g. 2 = IVD L5/S1; 3 = vertebra L5; 4 = IVD L4/L5; 5 = vertebra L4 etc.).
