摘　　要：目的探讨经直肠双重超声造影、CT、MRI检查在直肠癌术前淋巴结转移中的应用价值。方法对48例直肠癌患者术前行经直肠双重造影,其中42例同时行CT检查,39例同时行MRI检查,分别对区域淋巴结转移情况进行N分期,并与术后病理比较。结果经直肠双重超声造影、CT及MRI诊断N分期的准确率分别为77.1%(37/48)、81.0%(34/42)及79.5%(31/39),三者比较差异无统计学意义。结论经直肠双重超声造影、CT、MRI均是术前诊断和评价直肠癌淋巴结转移情况的有效方法。Objective To investigate the clinical value of double contrast-enhanced ultrasonography（DCUS）,CT and MRI in preoperative evaluation of lymph node metastasis in rectal cancer. Methods Forty-eight patients with rectal carcinoma underwent DCUS,forty-two cases were examined by CT and thirty-nine cases by MRI examination. The results of N staging were compared with histopathology findings of the resected specimens. Results The diagnosing accuracy of N staging of the rectal cancer by DCUS,CT and MRI scanning were 77.1%（37/48）,81.0%（34/42） and 79.5%（31/39）,respectively,there were no significant difference among the three methods. Conclusion DCUS,CT and MRI are useful for correct preoperative identification and precise evaluation of lymph node metastasis in rectal cancer.
