目的探讨多排螺旋CT(multi-detector-row CT,MDCT)在乳腺癌诊断和术前评估中的价值.方法回顾性分析2004年1月至2007年12月经手术后病理证实的54例乳腺癌患者(其中31例同时行MRI检查)的MDCT资料,就病灶的位置、范围与术后病理及MRI结果进行比较.结果 54例乳腺癌患者所有病灶均在增强图像上有明确显示,MDCT对病灶范围显示准确率为87%,根据MDCT结果而采用保乳手术的39例中,术中切缘阳性率为8%(3/39).MDCT和MRI对于病灶和评估的准确率相比差异无统计学意义(x2=0.5,P＞0.05).结论 MDCT可以较准确地对乳腺癌位置及范围进行评估,对乳腺癌手术有较大的指导价值.

Objective To evaluate the accuracy of multi-detector-row CT (MDCT) in the diagnosis and preoperative evaluation of breast cancer. Methods From January 2004 to December 2007,the clinical data of 54 cases wih pathologically proved breast cancer undergoing preoperative MDCT scan (31 cases also underwent MRI scan) were retrospectively analyzed at our hospital. Surgical planning was based on MDCT assessment. The extent and location of tumor depicted by MDCT,MRI and pathology were compared. Results Breast carcinoma was diagnosed by MDCT in all the cases. In these 54 patients,MDCT achived an accuracy of 87% in evaluating the extent of tumor. Based on MDCT,39 cases underwent BCT surgery with a 8% margin positive rate. MDCT and MRI had no significant difference in accuracy of evaluation on the extent of tumor ( x2 = 0. 5, P ＞ 0. 05 ). Conclusions MDCT accurately assesses the extent and location of breast cancer, proving its value in preoperative evaluation of breast cancer.
