目的 探讨螺旋CT扫描及其多平 面重建技术(MPR)在腕舟骨骨折诊断中的 应用价值。方法 回顾性分析59例腕舟 骨骨折患者螺旋CT及X线片影像资料，比 较两种方式诊断腕舟骨骨折准确性，分 析螺旋CT及MPR诊断腕舟骨骨折分型情 况。结果 螺旋CT及MPR诊断腕舟骨骨折 的准确率为98.31%明显高于X线平片的 71.19%，差异有统计学意义(P＜0.05)； 螺旋CT及MPR诊断腕舟骨关节的分型显 示，5.17% A1型，13.79% A2型，5.17% B1型，43.11% B2性，20.69%B3型， 12.07% B4型。结论 螺旋CT及MPR可提高 腕舟骨骨折的诊断准确性，明确骨折分 型，可为确定治疗方案可供客观资料。

Objective To explore the application value of spiral CT scanning and multiplanar reconstruction (MPR) in the diagnosis of carpal scaphoid fracture. Methods The CT and X-ray imaging data of 59 patients with carpal scaphoid fracture were analyzed retrospectively. The accuracy in the diagnosis of carpal scaphoid fracture was compared between the two methods. The status of spiral CT and MPR in the diagnosis of carpal scaphoid fracture type was analyzed. Results The accuracy of spiral CT and MPR in the diagnosis of carpal scaphoid fracture (98.31%) was significantly higher than that of X-ray plain film (71.19%) (P<0.05). Spiral CT and MPR in the diagnosis of carpal scaphoid joint type showed that there were 5.17% A1 type, 13.79% A2 type, 5.17% B1 type, 43.11% B2 type, 20.69%B3 type and 12.07% B4 type. Conclusion Spiral CT and MPR can improve the accuracy in the diagnosis of carpal scaphoid fracture. They can determine the type of fracture and provide objective data for the determination of treatment regimen.
