This review describes the use of cross-sectional imaging in the staging of colorectal carcinoma and detection of local recurrence. The contributions of CT, MR imaging, and sonography are discussed and illustrated. Colorectal carcinoma is the second most common tumor in the United States and the most common cancer in the gastrointestinal tract. The prognosis for patients with this neoplasm is closely related to the extent of tumor at the time of diagnosis. Accurate noninvasive preoperative assessment of tumor stage by one or a combination of radiologic techniques would enable appropriate treatment to be planned in each case. Also, determination of possible tumor recurrence would permit effective monitoring of success of therapy and surgical intervention for recurrent disease before widespread metastasis occurs.
本综述描述了横断面成像在结直肠癌分期及局部复发检测中的应用。讨论并举例说明了CT、磁共振成像（MR成像）及超声检查的作用。结直肠癌是美国第二常见的肿瘤，也是胃肠道最常见的癌症。该肿瘤患者的预后与诊断时肿瘤的范围密切相关。通过一种或多种放射学技术对肿瘤分期进行准确的术前无创评估，将有助于针对每个病例制定合适的治疗方案。此外，确定可能的肿瘤复发情况将有助于在广泛转移发生之前，有效监测治疗效果以及对复发性疾病进行手术干预。
