CT结肠成像术(CT colonography,CTC)是指采用螺旋CT扫描和后处理获得高清晰的二维和三维结肠图像的成像技术,又称CT仿真结肠镜(CT virtual colonoscopy,CTVC),1994年由Vining等[1]首次报道。根据临床检查目的不同,分为筛查性、监视性和诊断性CTC[2]。随着多层螺旋CT(MSCT)的快速发展,CTC广泛应用于临床,本文针对近年来CTC的临床应用进展作一综述。
CT colonography (CTC) refers to the imaging technique of obtaining high-resolution two-dimensional and three-dimensional colon images by spiral CT scan and post-processing, also known as CT virtual colonoscopy (CTVC) Vining et al [1] first reported. According to the purpose of clinical examination is divided into screening, surveillance and diagnostic CTC [2]. With the rapid development of multi-slice spiral CT (MSCT), CTC is widely used in clinic. This article reviews the clinical application of CTC in recent years.
