Vertebrae segmentation on MRI

Spine segmentation on MRI, vertebra by vertebra: TotalSegmentator MRI outlines each level from C1 to L5, plus the sacrum. Every person in a study then has the same level names, so a measure can be taken at L3 or T12 in all of them, and vertebral size and shape can be compared between groups.

Find answers to research questions like: How do vertebral size and shape vary with age and sex? Does the signal inside a vertebra differ from one level to the next? Do level names stay consistent between sequences in the same person?
