Belly Button Ring

 

There is a belly button ring over L4 on this Hologic lumbar spine image. The patient declined to remove the ring for the DXA scan. Because the artifact overlies bone, L4 would be removed from analysis.

Case Description:

This Hologic lumbar spine scan shows a naval ring over L4. The patient declined to remove the naval ring, so L4 should be removed from analysis.
