The myelogram is an x-ray examination of the spinal cord and vertebral canal after injection of a contrast medium or air into the spinal subarachnoid space. This diagnostic procedure is particularly valuable for evaluating spinal cord abnormalities caused by tumors, herniated intervertebral disks, or other lesions. An arthrogram is an x-ray study of a joint. A bone scan is used to detect primary bone tumors, metastatic bone disease, osteomyelitis, osteoporosis, inflammation, bone or joint infections, and stress fractures.
