Sixty-four-section CT colonography with water enema combines intracolonic neutral contrast agent with high-resolution CT images of the abdomen. Owing to submillimeter isotropic voxels, high-quality reformatted images are obtained. High-resolution images offer added value for the detection and localization of colonic lesions, evaluation of the local extent of the disease, and depiction, if any, of synchronous colorectal lesions and distant metastases. Sixty-four-section CT colonography with water enema has a major role in the evaluation of patients with colon cancer before planning therapy. It can be used to complement failed or incomplete colonoscopy and investigate the colon in elderly patients.
水灌肠六十四排 CT 结肠成像结合了腔内中性对比剂和腹部高分辨率 CT 图像。由于亚毫米等方像素，可获得高质量的重建图像。高分辨率图像为结肠病变的检测和定位、疾病局部范围的评估以及同时存在的结直肠病变和远处转移的描述提供了附加价值。水灌肠六十四排 CT 结肠成像在计划治疗前评估结肠癌患者方面具有重要作用。它可用于补充失败或不完全的结肠镜检查，并用于检查老年患者的结肠。
