PURPOSE
To assess the clinical value of second-look ultrasound (US) examination for the evaluation of additional enhancing lesions detected on magnetic resonance (MR) imaging.
MATERIALS AND METHODS
Between May 2008 and February 2011, 794 consecutive patients with histologically confirmed breast cancer underwent breast MR imaging. We included 101 patients with 132 additional enhancing breast lesions detected on MR imaging who underwent second-look US. The imaging features and lesion category according to the Breast Imaging and Reporting and Data System (BI-RADS) were assessed with MR and US imaging, respectively.
RESULTS
According to the BI-RADS system, 67 lesions (50.8 %) were classified as category 0, 33 lesions (25.0 %) as category 3, and 32 lesions (24.2 %) as category 4. Of the 67 indeterminate lesions on MR imaging, 34 (50.7 %) were demonstrated on second-look US. 11 of these 34 lesions showed suspicious sonographic features, including 1 lesion that showed malignancy (9.1 %, 1/11). Most of the suspicious lesions on MR imaging (26 of 32 BI-RADS category 4 lesions, 81.3 %) were demonstrated on second-look US, and 17 were malignant (65.4 %, 17/26). Of the 6 BI-RADS category 4 lesions without sonographic correlation, 1 was malignant (16.7 %, 1/6).
CONCLUSION
Second-look US examination was useful for evaluating MR-detected lesions in patients with breast cancer.
目的
评估二次超声（US）检查在评估磁共振（MR）成像中检测到的额外强化病变方面的临床价值。
材料与方法
2008年5月至2011年2月期间，794例经组织学确诊的乳腺癌患者接受了乳腺MR成像检查。我们纳入了101例在MR成像中检测到额外乳腺强化病变并接受二次超声检查的患者。根据乳腺影像报告和数据系统（BI-RADS），分别通过MR和US成像评估成像特征和病变类别。
结果
根据BI-RADS系统，67个病变（50.8%）被分类为0类，33个病变（25.0%）为3类，32个病变（24.2%）为4类。在MR成像中67个不确定病变中，34个（50.7%）在二次超声检查中显示出来。这34个病变中有11个显示出可疑的超声特征，其中1个病变显示为恶性（9.1%，1/11）。MR成像中大多数可疑病变（32个BI-RADS 4类病变中的26个，81.3%）在二次超声检查中显示出来，其中17个为恶性（65.4%，17/26）。在6个与超声无相关性的BI-RADS 4类病变中，1个为恶性（16.7%，1/6）。
结论
二次超声检查有助于评估乳腺癌患者中MR检测到的病变。
