FAQs related to X - Ray L S (Lumbar Spine) AP & LAT Views

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.
