2、结果:62例外伤后,X线检查阴性或可疑足跗骨骨折的SCT扫描并重建后, 39例显示有骨折, 其中距骨(talus)骨折5例, 跟骨calcaneus骨折8例, 舟骨(navicular bone)骨折6例,楔骨cuneiform bone骨折11例, 骰骨cuboid bone骨折9例。结论:螺旋CT及后处理技术对临床怀疑足跗骨骨折而普通X线(DR)不能确诊为骨折的病例能准确地作出准确诊断, 当X线平片检查阴性或可疑跗骨骨折应及时行SCT检查。关键词:跗骨(tarsal bones)骨折;隐匿性骨折;螺旋CT;图像后处理技术The Value of Postprocessing Techniq
