乳腺良恶性肿瘤的高频超声图像特征及误诊分析(附86例分析)

目的:分析乳腺良恶性肿瘤的超声特征及超声误诊原因,提高乳腺肿瘤超声定性诊断的符合率。方法:对86例乳腺肿瘤进行二维超声检查,与病理结果进行对比分析,并分析超声误诊原因。结果:86例乳腺肿瘤中良性34例,恶性52例,肿块检出率100%。超声诊断与病理诊断符合率为89.5%,误诊率为10.5%。良恶性乳腺肿瘤的声像图有明显差异,主要表现在两者边界、色膜、形态、回声分布、后方声衰减、钙化灶有无及形态等方面。结论:高频声像图上乳腺良恶性肿瘤表现有一定差异,为分析乳腺肿瘤性质提供了重要信息。

Comparative analysis of breast benign and malignant tumor by high frequency ultrasound and analysis of misdiagnosis

Objective:To analyse the high frequency sonographic features of br east benign and malignant tumor and the cause of misdiagnosis of ultrasound .Methods:Eighty-six patients of breast tumor were examined by two-dimensio n ultrasonog-raphy and compared with the pathological examination,and also ana lysed the cause of misdiagnosis of ultrasound.Result:A-mong the86cases, 34were benign and52were malignant.The detected rate of tumor was100%w hile the qualitative rate was89.5%.There were significant differences in the acoustic images between benign breast tumors and malignant ones.They were mainly manifested as that whether or not there were clear border,capsules,mo rphologic change,echo distribution,and calcific focus ear.Conclusion:On ult rasonogram,benign and malignant breast tumors have some different features. The ultra-sonogram feature could be used as an important reference for analyz ing the property of breast tumor.
