摘　　要：目的:探讨X线数字断层融合技术在诊断颈椎寰枢关节检查中的应用价值。方法:对32例临床症状表现为斜颈、颈部疼痛、颈部旋转活动受限的患儿,征得患者及家属同意,均同时进行寰枢关节张口位+侧位常规X线平片及数字断层融合成像扫描,评价2种成像方法所获得的寰枢关节图像质量及对患儿寰枢关节半脱位的诊断情况。结果:32例患儿中,经X线数字断层融合技术成像扫描发现14例患儿颈椎寰枢关节半脱位,而常规X线检查仅确诊3例,漏诊8例,怀疑半脱位3例。断层融合成像和常规X线检查的图像优质率分别为90.6%和56.3%。结论:X线数字断层融合技术能明显改善常规X线寰枢关节影像的图像质量,尤其在患儿配合不当及骨关节结构复杂的情况下,具有重要的诊断价值及临床意义。Objective To discuss the clinical application value of X-ray digital tomosynthesis technique in children cervical atlantoaxial subluxation examination, bletheds Thirty-two children were selected who had clinical manifestations including ankylodeire, pain in cervical part and rotation restriction. X-ray radiography and digital tomosynthesis scanning about atlantoaxial joint, approved by the patient and his family member, were performed during mouth opened and closed, and image quality and diagnostics result were evaluated. Results Fourteen among thirty-two cases showed subluxation by digital tomosynthesis scanning, and three cases were diagnosed and eight were missed by X-ray radiography, just three cases were suspected of subluxation. There were 90.6% of the images got by tomosynthesis scanning and 56.3% of the images by X-ray radiography had high quality. Conclusion Image quality about atlantoaxial joint is improved obviously through X-ray tomosynthesis scanning. Important clinical diagnosis value is found especially in complicated bone joint structure and uncooperative patients.
