DefinitionThe neck X-ray involves the 7 cervical (neck) vertebrae that are separated by flat pads of cartilage which cushion the vertebrae.
How the test is performedThe test is performed in a hospital radiology department or in the health care provider's office by an X-ray technician. You will be asked to lie on the X-ray table and assume various positions. If the X-ray is to determine injury, care will be taken to prevent further injury. The X-ray machine will be positioned over the neck area. You may be asked to stop breathing while the picture is taken so that the picture will not be blurry. Usually three to seven different views are needed.
