摘要
①目的 评价多层螺旋CT(MSCT)扫描检查对直肠癌浸润和淋巴结转移的诊断价值。②方法 对4 1例直肠癌病人行扫描前充气灌肠、MSCT增强扫描 ,扫描后在工作站行多层面重建、薄层重叠重建 ,将影像诊断结果与手术病理结果进行对照。③结果 MSCT扫描对直肠癌浸润和淋巴结转移诊断的总准确率分别为 85 .3%、78.0 %。评价肿瘤浆膜外浸润的灵敏度和特异度分别为 91.1%和 71.4 %。判断淋巴结转移的灵敏度和特异度分别为 96 .6 %和 72 .7%。④结论 MSCT扫描重建能充分显示直肠癌与盆腔内组织的关系 ,能清楚显示直肠周围的淋巴结 ,对直肠癌浸润和淋巴结转移诊断价值较高。
Objective To evaluate the diagnostic value of multi-slice helical CT(MSCT) scanning for invasion and metastasis of rectal carcinoma. Methods Forty-one patients with rectal carcinoma underwent MSCT enhanced scan after cleansing enema and rectal air insufflation. Multi-planar reformation and thin-section overlapping reformation were performed at workstation after the scanning. The MSCT findings were compared with the pathological results obtained surgically. Results The accuracy rate of MSCT in diagnosing invasion and metastasis of rectal carcinoma was 85.3% and 78.0%, respectively. Sensitivity and specificity for serosal infiltration was 91.1% and 71.4%, and for lymph node involvement 96.6% and 72.7%, respectively. Conclusion MSCT scanning can demonstrate the relationship between rectal carcinoma and pelvic tissues, display clearly lymph nodes around the rectum, which is of high value in the diagnosis of invasion and metastasis of rectal carcinoma.
