Thoracic spine x-ray

Thoracic spine x-ray

Definition

A thoracic spine x-ray is an x-ray of the twelve chest (thoracic) vertebrae. The vertebrae are separated by flat pads of cartilage that cushion them.

Alternative Names

Vertebral radiography; X-ray - spine; Thoracic x-ray; Spine x-ray; Thoracic spine films; Back films

Why the test is performed

The x-ray helps evaluate bone injuries, disease of the bone, tumors of the bone, or cartilage loss.

How the test is performed

The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. You will lie on the x-ray table and assume various positions. If the x-ray is to determine an injury, care will be taken to prevent further injury.

The x-ray machine will be positioned over the thoracic area of the spine. You will hold your breath as the picture is taken, so that the picture will not be blurry. Usually2 or3 views are needed.

How to prepare for the test

Inform the health care provider if you are pregnant. Remove all jewelry.

How the test will feel

Th test causes no discomfort. The table may be cold.

What the risks are

There is low radiation exposure. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks of the x-ray.

Special considerations

The x-ray will not detect problemsin the muscles, nerves, and other soft tissues,because theycan't be seen well on an x-ray.

What abnormal results mean

The abnormalities the test will pick up include fractures, dislocations, thinning of the bone (osteoporosis), and deformities in the curvature of the spine. The test may also detect bone spurs, disk narrowing, and degeneration of the vertebrae.
