摘　　要：目的探讨多层螺旋CT(MSCT)在陈旧性骨折诊断和鉴别诊断中的应用。方法选取31例陈旧性骨折病例。采用MSCT平扫结合多平面重建(MPR),表面遮盖成像(SSD)和透明化X线模拟投影(see-through)诊断并与普通X线、常规CT结果对比。结果MSCT及后处理技术正确鉴别31例。X线平片(22例)漏、误诊3例,疑似陈旧性骨折4例。常规CT(17例)计数错误2例。结论MSCT及后处理技术弥补了传统影像学的不足,对陈旧性骨折的鉴别具有重要的实用价值。Objective To explore the application of multi- slice spiral computed tomography （MSCT） in the diagnosis and differential diagnosis of old fracture. Methods 31 cases of old fractures were scanned with MSCT. The features of plain MSCT, multiplanar reformation （MPR）, surface shaded display （SSD） and see - through were analysed in comparison with that of X - ray or routine CT. Results 31 cases were diagnosed correctly with MSCT and post - processing function. Of 22 cases with X - ray plain films, 3 cases were misdiagnosed or underdiagnosed and 4 cases were uncertain. 2 of 17 cases were wrong count with routine CT images. Conclusion MSCT is helpful supplement ror traditional radiology and might be of practical significance to identify old fracture.
