Answer to Question 1

B
Explanation: Myelography is the study of the spinal column after injecting opaque contrast material; it is particularly useful in identifying a herniated nucleus pulposus disk pinching a spinal nerve. A dual-energy absorptiometry is a measurement of bone density using a low-dose X-ray for the purpose of detecting osteoporosis. A bone scan is a nuclear medicine procedure especially useful in identifying stress fractures, observing progress of treatment for osteomyelitis, and locating cancer metastases to the bone. An arthrography is a visualization of a joint by radiographic study after injection of a contrast medium into the joint space.
