高频声像图及彩色多普勒血流显像诊断乳腺癌的分析

EVALUATION OF HIGH FREQUENCY ULTRASONOGRAPHY AND CDFL IN DIAGNOSIS OF BREAST CARCINOMA

目的 :探讨高频声像图与彩色多普勒血流显像对乳腺癌的诊断价值。方法 :对 98例经手术病理证实的乳腺癌的高频声像图 (HFU )与彩色多普勒血流显像 (CDFI)特征进行回顾性分析 ,并与病理和同期手术的4 0例乳腺良性肿块进行对照分析。结果 :术前乳腺癌超声诊断符合率 84 .7% (83/ 98) ;误诊率 8.2 % (8/98)。肿块血流检出率 87.8% (86 / 98) ;77.6 % (76 / 98)血流信号丰富程度分级为Ⅱ～Ⅲ级。收缩期峰速均值为 36 .2 +1 2 .5cm /s。平均阻力指数 (Ri) 0 .73+0 .0 5。而良性组 ,血流信号检出率 5 6 .5 % (2 6 /4 6 )Ⅱ～Ⅲ级血流 1 7.4 % (8/4 6 ) ,收缩期峰速均值 1 9.6 +9.2cm/s ,Ri0 .6 2 +0 .0 4两组之间存在显著差异 (P <0 .0 0 1 )。结论

Objective:To study diagnostic value of high frequency ultrasonography(HFU) and color doppler flow imaging(CDFI) for breast carcinoma. Methods:HFU and CDFI findings were reviewed and analysed in 98 cases confirmed breast carcinoma. Compared with Pathology and 46 cases breast benign masses which operated in the same time. Results:Diagnosis-coincidence rate and misdiagnosis rate for breast carcinoma was 84.7%(83/98) and 8.2%(8/98). The detection rate of flow signals in malignant and benign breast masses was 87.8%(86/98) and 56.5%(26/46). Flow signals of 77.6%(76/98) and 17.4%(8/46) belonged to Ⅱ-Ⅲ level. The systolic peak flow velocities both in two groups was 36.2±12.5cm/s and 19.6±9.2cm/s(P>0.05). The average resistance index(Ri) was 0.73±0.05 and 0.62±0.04(P<0.001). There was a significant difference between malignant tumors and benign masses.Conclusions:If combined HFU with CDFI in comprehensive analysis of breast masses, the diagnostic accuracy of breast carcinoma would be increased.
