Not certain that this is even important. On my mri pics, there is a very slight bulge in a thoracic disc. But the curious part is the shape of the disc at that point and below. They are not the typical oval shape. The disc appears to have "mountains/hills" into the vertebra. As you pan thru the mri slices, it goes all the way thru.
Has anyone ever had this on their mri? Does it mean anything?
