彩色多普勒超声与钼靶X线联合应用对乳腺癌的诊断价值

Diagnostic value of color Doppler ultrasonography combined with mammography on breast cancer

目的 探讨彩色多普勒超声与钼靶X线联合应用对乳腺癌诊断的价值.方法 乳腺癌患者90例和良性乳腺病变22例,分别对单独用彩色多普勒超声和钼靶X线及两者联合应用进行比较.结果 乳腺癌血流信号丰富,以Ⅱ～Ⅲ级为主（76.32%）,乳腺良性病变血流信号少,以0～Ⅰ级为主（87.10%）;乳腺癌血流检出率为89.48%高于乳腺良性病变血流检出率38.71%（x2=4.57,P＜0.05）;钼靶摄片检查诊断为乳腺癌者68例（75.5%）,其中钼钯检出直径≤2.0 cm者38例（55.8%）高于直径≤1.0 cm者30例（44.4%）（x2=3.97,P＜0.05）;联合检查符合率85.7%（96/112）明显高于彩色多普勒超声符合率72.3%（81/112）和X线钼靶符合率75.8%（85/112）（x2=3.87,x2=3.85,均P＜0.05）.结论 联合应用可以提高乳腺癌的诊断准确率,是乳腺影像学检查最佳组合.

Objective To investigate the value of high frequency 2-Dimensional and color Doppler flow imaging combined with mammography on the diagnosis of breast cancer. Methods 90 patients with breast cancer and benign breast lesions in 22 cases, respectively, separate by color Doppler ultrasound and mammography and their combination were compared. Results The blood flow signals were Ⅱ～Ⅲ grade（76.32% ） in breast cancer and benign breast lesions less blood flow to 0 ～Ⅰ grade （ 87.10% ）; The detection rate of blood flow 89.48% in breast cancer were significantly higher than 38.71% in benign breast lesions （ x2 = 4.57, P ＜ 0. 05 ）; 68 cases （75.5 % ） were diagnosed by mammography 38 cases（55.8% ） in diameter≤2. 0em were significantly higher than 30 cases（44.4% ） in ≤ 1.0 cm（ x2 = 3.97, P ＜ 0. 05 ）; The corresponding rate of Joint Inspection 85.7 % （96/112） was higher than the r 72.3% （81/112） in color Doppler ultrasound and 75.8% （85/112） in mammography （ x2 = 3.87, x2 = 3.85, all P ＜0. 05 ）. Conclusion Color ultrasonography combined with mammography could raise diagnostic rate of breast cancer.Their combination is the best one of breast imaging examinations.
