摘　　要：目的:探讨多层螺旋CT(MSCT)后处理技术诊断隐匿性骨折的应用价值。方法:对52例X线平片结果阴性,而临床高度怀疑骨折的急诊外伤患者行MSCT容积扫描后,将原始图像进行多平面重组、最大密度投影、容积再现法成像等后处理。分析各图像显示骨折情况的能力。结果:52例X线平片中未显示骨折的患者,通过MSCT后处理技术49例显示骨折,其中眼眶骨折9例,脊柱骨折12例,髋关节骨折7例,胫骨平台骨折9例,腕骨骨折2例,跟骨骨折3例,肩胛骨骨折1例,肋骨骨折6例。排除骨折3例,阳性率94.2%。结论:MSCT后处理技术对隐匿性骨折能够准确地作出诊断,为临床选择治疗方案及预后评估提供可靠依据。Objective：To evaluate the multi-slice spiral CT（MSCT） postprocessing technique in the diagnosis of occult fractures. Methods：The MSCT was performed in 52 patients whose X-ray results were negative but highly suspected as occult fractures by clinicians;the raw data of all the cases were processed respectively by image reconstruction including multiple planar reconstruction, maximum intensity projection and volume rendering technique;then the results were compared. Results：Of the 52 patients presenting non-fracture by X-ray,49 were proved fractures by postprocessing technique：9 cases in the orbital,12 cases in the spine,7 in the hip joint,9 in the tibial plateau,2 in the Carpal bone,3 in the calcaneal,1 in the shoulder blade and 6 in the rib. The MSCT images of the other 3 cases showed negative. The positive rate reached 94. 2%. Conclusions：MSCT can make accurate diagnosis of occult fractures, and provide reliable basis for the selection of therapy project and estimation of the prognosis.
