Scoliosis in clinical terms refers to a condition in which one or several segments of the spine deviate from the midline of the body in the coronal plane and bend to the side, the presence of such a condition can lead to a deformity of the spine. Medical research suggests that scoliosis is most often found in the cervical and thoracic spine, but may also occur in the low back alone. Clinical studies have shown that scoliosis is more common in adolescents, and the incidence of scoliosis in adults has been increasing in recent years. When scoliosis occurs, prompt clinical intervention is required to prevent its impact on health.
The clinical treatment for patients with scoliosis is both surgical and non-surgical, with surgical treatment being performed for patients with a Cobb angle of 40° and some patients with less than ideal results from non-surgical treatment. In the treatment of patients with scoliosis, accurate diagnosis is essential, and the common diagnostic modalities include CT and MRI. However, because these diagnostic methods are performed in the supine position, it is difficult to clarify the changes in the spine during compression, resulting in less accurate results. Compared to CT and MRI, DR is used in a standing position, which has less impact on the changes in the spine and provides more accurate results, thus facilitating subsequent diagnosis and treatment.
The clinical need to have a comprehensive understanding of the patient’s spine, so the preoperative and postoperative need to use DR radiographs to facilitate analysis, diagnosis and postoperative observation of the treatment effect. Large field of view dynamic DR can be a long size photography of the patient’s spine, a single shot to obtain a complete panoramic image of the spine. The diagnosing physician can measure the bio-angle and Cobb angle of the whole spine from the photographed images, which provides an important diagnostic basis for the preoperative and postoperative examination of patients with scoliosis correction.
The whole spine is photographed by large-field dynamic DR, which provides uniform and clear images with natural transition at the junction. It is also easier to operate, eliminating the need for a second film and then stitching the images together, resulting in shorter and more efficient shooting times. It reduces radiation dose and provides clinicians with more accurate diagnostic information. Non-stitched images can ensure the accuracy of data from both leg measurements (such as force lines) and effectively avoid the loss of photographic information. It gives the surgeon accurate preoperative diagnostic data and improves the success rate of surgery.
In summary, large field of view dynamic DR for whole spine imaging can clearly present the bone and joint structure, can measure the angular value based on the panoramic spine image, can well reflect the true proportion and length of the bone, provides more accurate data for clinical diagnosis and treatment, and has important clinical application value.
