摘要
目的改善CT扫描技术以提高鼻骨骨折的CT诊断正确率。材料和方法对60例临床和CT诊断的鼻骨骨折病人和40例正常志愿者的HRCT横断位和改良冠状位扫描图像进行回顾性分析。结果对照组CT改良冠状位显示鼻骨孔35对,优于横断面扫描(显示20对);60例鼻骨骨折中改良冠状位扫描检出鼻骨骨折58例(96.7%),高于横断位检出(42例,70%),但鼻区并发症检出(17例)明显低于横断位(46例)。结论改良冠状位HRCT扫描可以提高鼻骨骨折检出率,结合横断位则更好,并可以提高鼻区并发症的检出率。
Purpose:To improve the correct diagnostic rate of nasal bone fracture using CT technique.Materials and Methods:Transverse-axial and modified coronal HRCT images in60cases of nasal bone fracture and40normal control were retrospectively analyzed.Results:The modified coronal CT scan showed more(35pairs)than axial scan(20pairs)in the control study.With modified coronal scan were more nasal bone fractures found(58)than with axial scan(42),but less complication of nasal region(17)than with axial scan(46).Conclusion:The modified coronal HRCT scan could improve the detection of the nasal bone fracture,and combination of coronal and axial scan could do better,also improve the detection of the nasal region complication.
