CT Scans
Cat Scans are not utilized as much as they once were for spinal conditions. MRI's provide better visualization of the neural elements and thus are preferred. CAT scans are generally utilized if an MRI isn't available or if there is metal that precludes someone from getting an MRI. Often patients who have had prior fusions get CAT scans with myelography since the metal distorts both the CAT and MRI pictures but the myleography makes the CAT superior to the MRI in such a case. As you look at these normal CAT scan pictures you will get a sense of the anatomy of each segment of the spine. Below is a normal cervical, thoracic and lumbar CAT scan of the spine in that order.
