Abstract

Computed tomography colonography (CTC) enables evaluation of the colon with minimal invasiveness. In spite of advances in multidetector CT (MDCT) technology and advanced software features, including electronic bowel cleansing (digital removal and tagging of fluid and debris), a number of potential pitfalls in the evaluation of the 3D volumetric dataset persist. The purpose of this article is to illustrate the strengths and potential pitfalls in the detection of colorectal polyps using CTC via a primary three-dimensional (3D) approach for evaluation.

摘要

计算机断层结肠成像（CTC）能够以微创方式评估结肠。尽管多排螺旋CT（MDCT）技术和先进软件功能取得了进展，包括电子肠道清洁（对液体和碎片进行数字去除和标记），但在评估三维容积数据集时仍存在一些潜在陷阱。本文旨在通过一种用于评估的主要三维（3D）方法，阐述使用CTC检测大肠息肉的优势和潜在陷阱。
