Two of the most commonly used diagnostic imaging procedures are the X-ray and CT scan. Specialists order imaging studies to get an accurate diagnosis and confirm any abnormality that could be the cause of back pain. This article explains the difference between x-ray and CT scan.
One of the most common imaging studies used is called an x-ray or Radiograph. A chiropractor orders an x-ray to evaluate the cause of pain and aid with the diagnosis and treatment. It provides detailed images of the spinal bone structures. It can help to rule out back pain caused by certain injuries or fractures including certain deformities and tumours. So with a condition such as Spondylolisthesis, the frequency of instability may also be detected.
An x-ray performs by shooting a beam of radiation through the body. As the bone consists of calcium it prevents the penetration of the radiation beam. The image of the bones appears as a (light coloured) shadow on the x-ray film. X-ray is not able to capture the images of the discs and nerve roots as these do not have calcium.
Women who pregnant are not recommended to undergo x-rays.
