【摘要】 目的 探讨核磁共振成像(MRI)在直肠癌术后复发诊断中的应用价值。方法 复习资料完整的直肠癌术后疑复发而行MRI检查的病例34例,应用标准SE序列, 行轴位T₁ WI、T₂ WI及矢状位T₁ WI序列扫描盆腔。2例行静脉Gd-DTPA增强扫描。结果 肿瘤复发27例,主要表现为骶前及会阴区肿物, T₁ WI呈低信号, T₂ WI呈混杂稍高信号,矢状位T₁ WI骶前脂肪间隙不连续或消失。复发肿瘤侵犯膀胱8例,侵犯前列腺6例, 明确骶尾骨转移6例, 盆腔淋巴结肿大3例。34例中，7例未见复发。结论 MRI对发现直肠癌术后复发并确定病变侵犯范围有重要价值。

    The value of MRI for diagnosis of recurrence of rectal carcinoma after surgical resection ZhaoTao,Wang Jichen,Jiang Xuexiang, et al. Department of Radiology, First Hospital of BeijingMedical University,Beijing 100034

    【Abstract】 Objective To define the possible role of magnetic resonanceimaging (MRI) for diagnosis of local recurrence of rectal carcinoma. Methods Pelvic MRIscans of 34 patients with rectal carcinoma received surgical resection were reviewed. SEsequence: Axial T₁ WI, T₂ WI and sagittal T₁ WI scanning ofpelvis were performed. Two patients had Gd-DTPA enhancement. Results Of the 34 patients27 developed recurrence. The major MRI findings were :tumor mass in the sacro-anterior andperineal regions, T₁ WI with low signal intensity, T₂ WI with mixedbut slightly high signal intensity, and discontinuity or loss of sacro-anterior fat spaceon sagittal T₁ WI. Cancer invasion could be detected to urinary bladder in 8patients, to prostate in 6 patients, to sacrum in 6 patiens. Pelvic lymph node enlargementwas seen in 3 patients. Seven patients did not show any signs of tumor recurrence.Conclusion Routine follow-up MRI scan after rectal carcinoma resection is useful inrevealing recurrence of cancer and its extent of involvement.
