【摘要】 目的 用高频超声对正常女性乳腺健康体检，探讨其在临床及乳腺普查方面的应用价值。 方法 对2006年1月－2009年12月间7 532例健康女性乳腺体检声像图进行分析，并对各年龄段的乳腺病变超声结果分布情况进行统计。 结果 共检出乳腺病变2 861例（37.98%），正常者4 671例（62.02%）。所有受检者中，囊性病变1 904例（25.28%），实性病变944 例（12.53%），混合性病变13例（0.17%），伴有副乳者692例。囊性病变及实性病变单侧多于双侧，混合性病变均为单侧。常见病中，囊性病变多于实性病变，发病年龄分布在20～30岁及31～40岁年龄段。 结论 高频超声作为女性乳腺疾病的一种常规检查，能对乳腺占位性疾病提供较为准确的诊断，对乳腺癌早期发现、早期诊断、早期治疗提供一种科学依据。【Abstract】 Objective To explore the clinical value of high-frequency sonography for normal clinical breast examination in breast screening. Methods From January 2006 to December 2009, 7 532 healthy women underwent breast sonography. The results of sonography in the individuals with different ages were statistically analyzed. Results Breast lesions were found in 2 861 cases (37.98%) and the other 4 671 were healthy. Among all of the individuals, 1 904 cases (25.28%) had cystic lesions, 944 (12.53%) had solid lesions and 13 (0.17%) had mixed lesions. There were 692 cases of accessory mammary tissue. Unilateral cystic nodules and solid nodules were more common than bilateral ones, whereas mixed nodules were usually sunilaterally. Cystic nodules were more common than solid nodules. Most common onset of breast lesions is in the individuals with the age of 20-30 and 31-40 years. Conclusion High-frequency sonography, as an examination for normal clinical breast screening provides more accurate diagnosis and early detection of breast lesions, which can provide scientific evidence for early detection, diagnosis and treatment for breast cancer.
