| 摘 要： | 目的:探讨螺旋CT容积再现技术(volume rendering technique,VRT)和多平面重建(multiplanar reconstruction,MPR)在颌面骨折中的应用价值。方法:对90例颌面部骨折病例行螺旋CT薄层扫描,VRT及MPR重建,分析其病变显示率和空间显示效果。结果:90例颌面部外伤病例共有203处骨折,VRT图像显示骨折187处,不能显示骨折16处,漏诊率7.88%;MPR图像显示全部骨折,通过调节窗宽窗位显示副鼻窦腔和软组织病变。结论:螺旋CT薄层扫描及后处理技术在颌面外伤病例中可做为常规检查,VR与MPR相结合能提高诊断准确率,对于临床诊断和治疗具有实际应用价值。 |
