摘要
作者用彩色多普勒超声检查了１０４例乳腺病变，发现恶性病变血流信号丰富，５６％为＋＋＋～＋＋＋＋级，良性病变血流信号较少，９０％为０～＋＋级。６５％的恶性病灶血管数≥３条，８７％的良性病变最多可有２条供应血管。良恶性病变的收缩期血流峰值分别为０．２４±０．２０ｍ／ｓ和０．３４±０．２２ｍ／ｓ（Ｐ＜０．０５）；阻力指数分别为０．６４±０．１４和０．７７±０．０９（Ｐ＜０．００１）。把病灶的形态、血流多少与脉冲多普勒频谱分析结果结合起来，对诊断乳癌的敏感性、特异性和正确诊断率分别达到９６．６％、９５．６％和９６．２％。并对乳腺Ｘ线摄影、二维超声及彩色多普勒超声的优缺点和临床应用进行了讨论。
Hundred four cases of breast diseases were examined by color Doppler ultrasono-graphy(CDUS).Malignant lesions were rich in blood flow signal and 56%were of + ++～++++grade while benign lesions had little blood flow signal and 90%were of 0～++grade。65%of the malignancy had more than 3 feeding vessels but for benignancy, 87%had only 2 vessels or even fewer。 Malignant lesions showed significantly higher peak systolic velocity (0.34±0.22m/s vs 0.24±0.20m/s,P<0. 05)and higher resistive index(0.77±0. 09 vs 0.64±0. 14, P<0.001)than benign diseases。When combining the morphologic changes with the quantity of blood flow sig-nal and spectrum analysis the sensitivity, specifity and overall accuracv for breast carcinoma were 96.6%, 95.6%and 96.2%respectively. The benefits and limitations as well as the clinical applica-tion of mammography,2-dimentional ultrasonography and CDUS were discussed.
