MSCT影像技术目前在临床上得到了广泛应用。与传统CT扫描比较,通过图像三维重建,以任意平面和任意角度的图像为临床医生提供完整、直观和易于精确定位的影像信息,使其能显示三维解剖结构,精确测量距离与表面积、体积,尤其可进行模拟外科手术,在骨科、整形外科、牙种植及正颌外科中得到了广泛应用。本文就颌面部MSCT三维图像重建在诊断中的应用进行了综述。 MSCT imaging technology is currently widely used in clinical practice. Compared with the traditional CT scan, the three-dimensional reconstruction of the image provides the clinician with a complete, intuitive and easy-to-locate image information at any plane and any angle so that it can display three-dimensional anatomical structures, precisely measure distance and surface area, volume, Especially for analogue surgery, orthopedics, plastic surgery, dental implants and orthognathic surgery has been widely used. In this paper, the application of three-dimensional reconstruction of maxillofacial MSCT in diagnosis is reviewed.
