摘要: 目的探讨高频彩色多谱勒超声在乳腺癌和乳腺增生症鉴别诊断中的价值。方法回顾性分析经手术病理确诊的50例乳腺癌患者,46例乳腺增生症患者(实性肿块型)的二维超声形态学7项指标、肿块内血流信号等级、动脉血流频谱参数及动脉频谱形态。结果癌症组与增生组二维超声7项指标比较差异具有统计学意义(P<0.01);癌症组血流信号明显高于增生组,多以Ⅱ或Ⅲ级为主,增生组以0或Ⅰ级为主,两组间比较差异具有统计学意义(P<0.01);癌症组收缩期流速峰值(Vmax)、阻力指数(RI)高于增生组,两组间比较差异具有统计学意义(P<0.05,P<0.01);癌症组与增生组动脉血流频谱形态两组间比较差异具有统计学意义(P<0.01)。结论高频彩色多谱勒超声在乳腺癌与乳腺增生症的鉴别诊断中具有较高的价值。Abstract: Objective Discussion on the value of the high-frequency color Doppler ultrasound in the differential diagnosis in the breast cancer and breast hyperplasia. Methods Retrospective analysis by opration to obtain the pathologiocal diagnose on 50 patients with breast cancer and 46 patients with breast hyperplasia(concrete tumour). Seven indexes in the tumour under the two-dimensional ultrasound morphology were observed. The blood stream signal, the artery blood stream frequency spectrum parameter and the artery frequency spect rum shape in the tumour were detected. Results In comparision, there are st riking differences ( P < 0. 01) in the seven indexes between the cancer group and the hyperplasia group under the two-dimensional ult rasound. The blood st ream signal in the cancer group is obviously higher than that in the hyperplasia group . The blood st ream signal in the cancer group is mainly level Ⅱor level Ⅲ,while the blood st ream signal in the hyperplasia group is mainly level 0 or level Ⅰ. In comparision, the differences between the two groups are remarkable ( P < 0. 01) . The cont raction time peak flow value (Vmax) and the resistance index ( R I) in the cancer group are higher than those in the hyperplasia group. In comparision, the differences between the two groups are remarkable ( P < 0. 05, P < 0. 01) . The differences in the artery f requency spect rum shape between the two groups are remarkable ( P < 0. 01) . Conclusion The high-frequency color Doppler ult rasound has the significant value in the differential diagnosis in the breast cancer and the breast hyperplasia.
