Why large-field dynamic DR must be used in the diagnosis of scoliosis


What is scoliosis? Scoliosis refers to a condition in which one or more segments of the spine deviate from the midline of the body in the coronal plane and curve to the side, which can lead to spinal deformities. Medical research suggests that scoliosis is most common in the cervical and thoracic spine, but can also occur in the lower back alone. Clinical studies have shown that scoliosis is most common in adolescents and has been increasing in adults in recent years. When scoliosis occurs, clinical intervention is needed to prevent it from affecting health.

Clinical treatment for scoliosis patients includes both surgical and non-surgical treatments. Surgical treatment is performed for patients with a Cobb angle of 40° and for those who do not have satisfactory results from non-surgical treatments. In the process of treating scoliosis patients, accurate diagnosis is crucial, and commonly used clinical diagnostic methods include CT diagnosis and MRI examination, etc. However, due to the fact that these diagnostic methods are not suitable for patients with scoliosis, they are not suitable for patients with scoliosis. However, since these diagnostic methods are performed in the supine position, it is difficult to clarify the changes in the spinal compression process, resulting in less accurate results. Compared with CT and MRI, DR adopts a standing position during treatment, which has less influence on the changes in the spine and provides more accurate results, thus facilitating subsequent diagnosis and treatment.

Clinical need to have a comprehensive understanding of the patient’s spine, so the preoperative and postoperative need to take X-rays with the help of DR to facilitate the analysis of the condition, a clear diagnosis and postoperative observation of the effect of treatment. Large-field dynamic DR can take long-size photographs of the patient’s spine and obtain a complete panoramic image of the spine in a single shot. The diagnostic doctor can measure the bio-angle and Cobb angle of the whole spine through the photographed image, which provides an important diagnostic basis for the pre- and post-operative examination of patients with deformity correction of scoliosis.

With large field of view dynamic DR for whole spine radiography, the image density is uniform, clear, and the transition at the edges is natural. The operation is more convenient, without the need for a second film and then image splicing, the shooting time is short, and the efficiency is high. It also reduces the radiation dose and brings more accurate diagnostic information to clinicians. The non-spliced image can ensure the accuracy of the measurement data of both legs (e.g. force line) and effectively avoid the loss of photographic information. Provides surgeons with accurate preoperative diagnostic data and improves the success rate of surgery.

In summary, large-field dynamic DR for total spine imaging can clearly present the bone and joint structure, and can measure the angle value on the basis of the panoramic spine image, which can well reflect the true proportion and length of the bones, providing more accurate data for clinical diagnosis and treatment, and has important clinical application value.
