| 目的 探讨MR、多层螺旋CT(MSCT)在乳腺良、恶性病变诊断中的价值。 方法 140例乳腺疾病患者接受检查,72例接受MR检查,68例接受MSCT检查。 结果 140例乳腺疾病共152个病灶分为两组,MR组72例80个病灶,MSCT组68例72个病灶。MR、MSCT两组检查结果与术后病理结果均呈较好的一致性(Kappa值均＞0.75);对乳腺癌MR、MSCT的敏感度分别为95.00％(38/40)、93.33％(42/45),特异度分别为90.00％(36/40)、85.19％(23/27),准确度分别为92.50％(74/80)、90.28％(65/72)。MSCT对乳腺癌腋窝淋巴结转移的术前检出率为71.43％(5/7),MR为10.00％(1/10)。 结论 MR、MSCT在乳腺良恶性病变鉴别方面都具有较高的诊断价值。 |

| Objective To investigate the value of MR and multi-slice CT (MSCT) in diagnosing breast benign and malignant lesions. Methods A total of 140 cases of breast diseases were examined, 72 received MR, 68 received MSCT examination. Results All cases with 152 lesions were divided into two groups: MR group 72 cases of 80 lesions and MSCT group 68 cases of 72 lesions. Good agreement was found between MR and MSCT results with pathology (Kappa values>0.75).The sensitivity of MR, MSCT for diagnosing breast cancer was 95.00% (38/40) and 93.33％ (42/45), the specificity was 90.00% (36/40), 85.19% (23/27), the accuracy was 92.50% (74/80) and 90.28% (65/72), respectively. Five axillary lymph nodes (5/7, 71.43%) of metastasis were preoperatively detected by MSCT, while one (1/10, 10.00%) lymph node was detected by MR. Conclusion MR and MSCT both have high diagnostic value in the identification of benign and malignant breast lesions. |
