Why do X-rays have to be filmed? Can’t the electronic version be used?Patients who take a full-length spine film are generally used for the examination of scoliosis, and the specific situation of scoliosis can be seen. Through the standing full-length film of the spine, the posture of the patient and whether the direction of the force is normal can be observed. There is no congenital bone dysplasia and so on.
Like some long-term disease, the posture has changed, and the compensatory scoliosis can be checked by full-length film. Front and side can be clearly seen.
The whole spine film is an important means to confirm the diagnosis. Therefore, the imaging department should try to do a good job of shooting and diagnosis, and cooperate with the attending doctor to confirm the patient’s condition.
