Radiographs (X-rays)

Printer Friendly Version

X-rays were discovered in 1895 and are the most common type of imaging study spine specialists rely on to confirm a diagnosis.  Through the years, x-ray technology has significantly improved.  For example, the amount of radiation needed to produce an x-ray is a mere fraction of what was needed in the past.

Hospitals, imaging and medical centers, and physician’s offices use x-ray to diagnose vertebral fractures, scoliosis, spondylosis, bone spurs (osteophytes), spondylolisthesis, and other spinal disorders.

What does an x-ray look like?

An x-ray is an image created in many contrasting shades of black, gray and white.  Since bones and other calcified structures are denser than soft tissue and absorb more of the electromagnetic radiation, they may appear almost white.  Muscle, fat and other soft tissues appear dark (black to gray tones).

Procedure Preparation

An x-ray requires no special physical preparation.  It is not necessary to restrict food or fluids prior to the test.  X-rays may not be safe for women who are pregnant; this should be discussed with the technician. Depending on the nature of the x-ray, patients may be asked to wear a hospital gown. Jewelry must be removed.

The technician who operates the x-ray machine usually stands behind a lead screen or in an adjacent room to minimize his or her exposure to radiation. In some cases, a lead apron may be used to protect parts of the body not being examined.

After the Procedure

X-ray films can be developed quickly, so patients are often advised to wait in the clinic until they are processed and evaluated.

Conclusion

X-rays are very useful in the diagnosis and treatment of many types of spinal conditions. They are one of the most commonly used imaging techniques for spine patients.
