X-RaY

X-ray images are produced by sending an x-ray beam through the body. The calcium in bone blocks penetration of the x-ray beam casting a shadow on the xray film

X-rays are obtained to view detail of the boney structures in the spine. They are useful in evaluating for

• instability (spondylolisthesis)

• tumors

• fractures

X-rays do not produce good images of discs, ligaments and nerve roots as they do not have any calcium

X-rays should be minimized in women who may be pregnant.
