Modern medical imaging facilitates the diagnosis and treatment of human diseases. However, few people are aware of the cons of radiation exposure from medical imaging. Emerging evidence reveals that cumulative doses of radiation exposure will increase the morbidity and mortality of pertaining cancer. As a special young population, patients with adolescent idiopathic scoliosis (AIS) suffer more radiation harms from repeated diagnostic imaging, most of which can be avoided in clinical practice. Accumulating evidence highlights reduced cancer risks of radiation exposure for AIS patients with low/zero radiation imaging modalities proposed, amongst which easy conversion from anterior-posterior (AP) to posterior-anterior (PA) projection for whole-spine radiographs should be stressed. It can greatly reduce radiation doses without compromising the quality of diagnostic imaging. Tight collimation combined with PA projection can further reduce radiation harms, and need to be spread to benefit people globally.
现代医学影像学促进了人类疾病的诊断和治疗。然而，很少有人意识到医学影像学辐射暴露的弊端。新出现的证据表明，辐射暴露的累积剂量将增加相关癌症的发病率和死亡率。作为一个特殊的年轻人群，青少年特发性脊柱侧凸（AIS）患者在重复诊断性影像学检查中受到更多的辐射危害，而这些危害在临床实践中大多是可以避免的。越来越多的证据强调了低/零辐射成像方式对 AIS 患者的辐射致癌风险的降低，其中应强调脊柱全长片从前位到后位（AP）到后前位（PA）的简单转换。这可以在不影响诊断图像质量的情况下大大降低辐射剂量。紧密准直结合 PA 投影可以进一步降低辐射危害，需要在全球范围内推广以造福人类。
