摘　　要：目的:探讨64层CT图像软阅读在诊断鼻骨骨折中的临床应用价值。方法:采用灯箱阅读和工作站软阅读回顾性分析40例灯箱阅读诊断为鼻骨骨折的外伤患者的影像学资料,比较2种读片方式诊断鼻骨骨折的差异。结果:采用灯箱阅读诊断为不伴有移位的线性骨折19处,软阅读诊断为10处,诊断符合率分别为52.6%和100%;灯箱阅读诊断复合骨折20处,软阅读诊断9处,诊断符合率分别为45.0%和100%;灯箱阅读显示伴移位的线性鼻骨骨折14处,软阅读显示12处,诊断符合率分别为85.7%和100%;灯箱阅读显示粉碎性骨折7处,软阅读显示10处,诊断符合率分别为70.0%和100%。对于不伴有移位的线性和复合性鼻骨骨折两种诊断方法间差异有统计学意义(P<0.05)。工作站软阅读可以明确诊断有无鼻骨骨折,可以准确区分鼻骨孔、鼻骨缝、正常变异、额突骨折和线性鼻骨骨折,判断鼻骨骨折方向、骨折多少及骨折移位情况。结论:工作站软阅读在鼻骨骨折中具有重要的诊断价值。Objective：To discuss the diagnostic value and clinical application of soft-copy reading with 64 slice spiral CT in nasal bone fracture.Methods：40 cases of nasal bone fracture diagnosed with lightbox-reading and soft-copy reading with work station were analyzed and compared retrospectively.Results：Linear fracture of nasal bone without displacement was 19 with light-reading,and 10 with soft-copy reading in workstation,with the diagnostic accuracy of 52.6% and 100% respectively;those of compound fracture of nasal bone were 20 and 9,with diagnostic accuracy 45.0% and 100%;linear fracture of nasal bone with displacement 14 and 12 of diagnostic accuracy 85.7% and 100%;comminuted fracture of nasal bone 7 and 10 of diagnostic accuracy 70.0% and 100%,outcoming with statistically significant difference between light-reading and soft-copy reading（P〈0.05）.With or without nasal fracture could be judged by soft-copy reading in workstation and still more accurate diagnosis of frontal process fracture,linear nasal bone fracture and some normal nasal variation such as nasal foramina,bone suture;and even the direction,the number and displacement of nasal fracture could be achieved.Conclusion：Soft-copy reading on workstation has important diagnostic value in nasal bone fracture.
