目的 比较超声、CT、MRI对子 宫内膜癌分期、粘膜层侵犯及淋巴结转 移的诊断价值。方法 回顾性分析2010年 1月-2015年4月我院收治且经病理证实为 子宫内膜癌的80例患者的临床资料，患者 术前均已接受超声、CT、MRI检查，且影 像学资料完整，比较不同影像学检查方法 对子宫内膜分期、粘膜层侵犯及淋巴结转 移的诊断价值。结果 MRI与病理分期符合 度最高，为97.5%；80例患者术后病理证 实肌层浸润58例，45例术前超声提示肌层 受侵，44例CT提示受侵，52例MRI提示受 侵；14例病理证实宫颈浸润，超声、CT、 MRI分别检出16例、12例、15例；术后病 理提示淋巴结转移9例，超声、CT、MRI分 别检出2例、8例、10例。结论 MRI在子宫 内膜癌术前分期、粘膜层侵犯、淋巴结转 移评估方面效能最佳，CT次之，超声最 低。

Objective To compare the diagnostic value of ultrasound, CT and MRI in endometrial carcinoma staging, mucosal invasion and lymph node metastasis. Methods The clinical data of 80 patients with endometrial carcinoma confirmed by pathology and treated in our hospital from January 2010 to April 2015 were retrospectively analyzed. All patients received ultrasound, CT and MRI examination before operation and the imaging data were complete. The value of different imaging methods in the diagnosis of endometrial staging, mucosal invasion and lymph node metastasis was compared. Results The conformity of MRI and pathological staging was the highest which was 97.5%; In 80 cases, 58 cases were confirmed with myometrial invasion by postoperative pathology. The preoperative ultrasound in 45 cases indicated invasion, CT in 44 cases indicated invasion and MRI in 52 cases indicated invasion. 14 cases were confirmed with cervical invasion. 16 cases, 12 cases and 15 cases were respectively detected by ultrasound, CT and MRI. Postoperative pathology showed lymph node metastasis in 9 cases. 2 cases, 8 cases and 10 cases were detected by ultrasound, MRI and CT respectively. Conclusion MRI is of the best effect in the evaluation of preoperative staging of endometrial carcinoma, mucosal invasion and lymph node metastasis in, followed by CT and ultrasound is the lowest.
