Know more about this test

An X-ray of the LS spine (lumbo-sacral spine) is a safe and painless test to visualise the area of the lower back which consists of five lumbar vertebrae (L1 to L5) and the sacrum (a triangular bone at the end of the spine). It also helps to visualise their intervertebral discs with the surrounding soft tissues like skin and muscles using small amount of radiation. The image is recorded on a special X-ray film. The X-ray image is black and white. Dense structures such as the bones, appear white and softer body tissues, such as the skin and muscles appear darker. The actual exposure time to radiation is usually less than a second, although the overall test may take 20-30 minutes.

FAQs related to X - Ray L S Spine AP LAT Standing View

What are the drawbacks of a bone X-ray?

X-ray images give a very clear view of the bones. However, it does not provide a good visual image of the soft tissues like tendons, muscles or fat tissue under the skin. Even the bone microfractures or complicated spine injuries are not clearly visible on the X Ray images. Apart from this, it also exposes the patient to some amount of radiations but the benefit of the information gained from an X-ray image outweighs the risk of radiations.

Who interprets the X-ray results?

The interpretation of an X-Ray image is carried out by a radiologist who analyses or reads the X-ray image and prepares a report of the findings which is shared with the patient.
