Inputs:
  • Sagittal Spine MRI  (Sagittal MRI of the spine)
Outputs:
  • Sagittal spine MR segmentation  (0: background, 1-25: different vertebrae numbered from the bottom (i.e. L5 = 1) 100: spinal canal 101-125 for partially visible vertebrae 201-225: different intervertebral discs (also numbered from the bottom, i.e. L5/S1 = 201))

Model Facts

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. The vertebrae are subsequently labeled between 1 and 24, with 24 being the lowest lumbar vertebra (L5). Vertebra which are not completely visible within the field of view of the MR image are labeled between 101 and 124. The intervertebral discs are labeled between 201 and 224 and are decided by the vertebra above it. The spinal canal is labeled as 100.
