Vertebrae and pelvis segmentation on CT

Each vertebra from C1 down to L6 has its own outline in this spine segmentation on CT, and MOOSE also outlines the sacrum and the left and right hip bones. Studies use it to count vertebrae, find variants at the border of the lumbar spine and sacrum, and place muscle and fat measurements at the same level in every participant. On PET or SPECT, uptake can be read bone by bone across the spine, sacrum, and hip bones, set against a reference region such as the liver.

Find answers to research questions like: How common are extra or fused segments where the lumbar spine meets the sacrum? How do sacrum and hip bone dimensions differ between women and men? How does uptake differ between the spine, the sacrum, and the hip bones?
