【摘要】 目的:评价螺旋CT三维成像对鼻骨骨折的诊断价值。方法:应用GE Lightspeed Plus多排螺旋机扫描仪,对86例鼻外伤患者进行鼻骨横断面扫描和VR成像,并对检查结果进行分析。结果:86例鼻外伤患者中,16例普通X线侧位平片未发现骨折(18.6%);螺旋CT VR图像均能清晰显示骨折线,其中单纯性鼻骨骨折44例(51.2%),并发上颌骨额突骨折19例(22.1%),上颌窦骨折8例,筛窦纸样板骨折9例,鼻中隔断裂6例。结论:鼻骨骨折的螺旋CT容积重建(VR)对茎突过长症的诊断有重要作用。更多还原

【Abstract】 Objective:To evaluate retrospectively the clinical value of spiral CT VR in diagnosing nasal bone fracture.Methods:86 patients with nasal bone fracture were scanned transversely and reconstructed with VR by GE Lightspeed plus multiple slices scaner.Results:Sixteen cases(18.6%) showed false negative with X-ray examination.There were 44 cases(51.2%) of simple nasal bone fracture and 44 cases(48.8%) compound fractures.Conclusion:Volume Rendering with spiral CT is a very useful method for the diagnosis of suspected longated styloid process.更多还原
