X-rays of your low back/pelvis is the most common imaging technique used to identify Bertolotti’s Syndrome. When looking at the x-rays, we are looking for an enlarged transverse process on the transitional vertebrae (usually L5, the lowest lumbar vertebrae). Sometimes though, if the x-rays are not clear enough, we may order a CT scan of your low back/pelvis to better assess the bony anatomy and to rule out any other pathologies that may be contributing to the pain such as sacroiliitis.
