【摘要】 目的探讨分析高频超声对乳腺肿瘤的临床诊断价值。方法选择经手术病理检查确诊的246例乳腺肿瘤患者,分析其声像图特征、彩色多普勒表现和血流阻力指数等临床资料,并与手术病理结果比较。结果乳腺癌良性患者与恶性患者的二维声像图在形态首发规则、是否具有钙化、边界是否清晰、包膜是否完整、是否具有血流信号等方面均具有明显差异性(P<0.05);良性肿瘤患者的Vmax、RI数值明显小于恶性肿瘤患者,具有统计学意义(P<0.05);良性肿瘤患者的Adler半定量的分级状况与恶性肿瘤患者的比较具有较大差异,具有明显差异性(P<0.05);良性肿瘤患者的彩色多普勒血流分级以0级、1级为主,恶性肿瘤以2级、3级为主要血流分布。良恶性肿瘤患者彩色血流分级方面具有较大差异性(P<0.05)。结合病理结果显示:超声诊断良性肿瘤准确率为94.61%(193/204),误诊率为5.39%(11/204);超声诊断恶性肿瘤准确率为88.10%(37/42),误诊率为11.90%(5/42);超声总诊断率为94.50%(230/246),误诊率5.50%(16/246)。结论高频超声对乳腺肿瘤具有较高的诊断准确率,并且为临床诊断提供具体的参考数据,是一种值得在临床上广泛推广的诊断手段。更多还原

【Abstract】 Objective To evaluate the clinical diagnostic value of high frequency ultrasound in breast tumors. Methods246 cases of pathologically confirmed breast cancer patients were selected. Clinical data including sonographic features,performance of color Doppler,blood flow resistance index were analyzed and compared with the pathologic findings. Results Two-dimensional sonogram of patients with benign and malignant breast cancer had significant difference in the form of the first rule,whether had calcification,whether had clear boundary,whether had complete envelope,whether had flow signals and other aspects( P <0. 05); Vmax,RI values of benign tumors were significantly less than that of malignant tumors,there had statistical difference( P< 0. 05); Adler semi-quantitative grading of benign and malignant tumors had statistical difference( P < 0. 05); color Doppler flow grades of benign tumors were mainly 0 and 1,and those of malignant tumors were mainly 2 and 3,there had statistical differences( P < 0. 05); Pathologic results showed that accuracy of ultrasound diagnosis of benign tumors was 94. 61%( 193 /204),misdiagnosis rate was 5. 39%( 11 /204); The accuracy of ultrasound diagnosis of malignancy was 88. 10%( 37 /42),misdiagnosis rate was 11. 90%( 5 /42); total ultrasound diagnosis rate was 94. 50%( 230 /246),misdiagnosis rate was 5. 50%( 16 /246).Conclusion The high-frequency ultrasound has a high accuracy rate in the diagnosis of breast cancer,and provide specific reference data for clinical diagnosis. It is worthy of clinical application.更多还原
