188枚良恶性乳腺肿块声像图识别

Identification of 188 benign and malignant breast masses with ultrasonography

目的 通过分析188枚经手术证实的乳腺肿块病理结果与术前超声声像图特征,以期对乳腺肿块的良恶性鉴别提出一个超声诊断的标准。方法 在本院接受手术治疗的185位乳腺肿块患者,手术切除肿块188枚,其中良性肿块107枚,恶性肿块81枚。使用仪器:Sequoia 512,探头为8MHz-13MHz宽频线阵探头。鉴别良恶性肿块的参数为:形状、边缘、边界回声、内部回声、后方回声、侧后声影、纵横比例。结果 各类良性肿块的诊断准确率为97％(104/107)。各类恶性肿块的诊断准确率为85％(69/81)。结论 为了提高超声对乳腺肿块的良恶性诊断准确性,必须考虑肿块的声像图特征,肿块与周围组织的关系以及不同病理类型的良恶性乳腺肿块的声像图特征。

Purpose To present our criterion about identifying breast masses on ultrasonography by comparing the sonographic features with the pathological results. Methods A total of 185 patients received operation among them were 107 benign and 81 malignacies breast masses The instrument was Sequoia 512 equiped with 8 - 13MHz wideband linear probe.The differential parameters of ultrasonography were the shape、mar-gin、boundary echogenicy、inner echogenicity、rear echogeniciry、side-wall posterior shadowing and length- thickness ratio. Results The diagnostic accuracy of ultrasound was 97.2% (104/107) in benign masses and 85.2% (69/81) in malignant masses. Conclusion In order to diagnose breast masses accurately with ultrasonography, it is necessary to consider the ultrasonographic characters of the mass, the relationship between the mass and its surrounding tissue, as well as the sonographic characters of different pathological types.
