[摘要]锥形束CT(CBCT)可以为口腔颌面部提供高分辨率的三维影像信息，是21世纪发展迅速的口腔颌面部辅助检查方法之一。已有大量的文献报道：CBCT所获得的三维图像准确性优于传统的二维影像；相对于螺旋CT，CBCT费时短、放射剂量小，在口腔临床工作中得到了广泛的应用。使用CBCT所获得的三维图像进行线距测量，其数据是否具有足够的准确性和可靠性，是目前研究的热点。本文就CBCT在口腔颌面部进行线距测量的准确性和可靠性作一综述，以期为临床应用提供参考。

Accuracy and reliability of cone-beam computed tomography in oral maxillofacial linear measurements Xu Ziqing, Feng Jing.(Dept. of Orthodontics, The Ninth People’s Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai 200011, China; Shanghai Key Laboratory of Stomatology, Shanghai 200011, China)
[Abstract]Recently, cone-beam computed tomography(CBCT)has become an important image technique for dento-maxilla facial applications, and it provides three-dimensional information with high resolution. Many research shows that CBCT measurements compared well to traditional radiography; compared with the standard medical CT, cost and dose are lower, which help it win wide attention in dental practice. Moreover, the accuracy and reliability for measuring different structures is still a hot research area. This review presented the accuracy and reliability of CBCT in oral maxillofacial linear measurements. ......
