超声弹性成像技术与彩色多普勒血流显像结合诊断乳腺肿瘤的对比评价

目的:评价超声弹性成像技术与彩色多普勒超声结合用于诊断乳腺肿瘤的有效性。方法:对乳腺肿瘤98例患者的138个乳腺结节分别运用超声弹性成像技术(UE)、彩色多普勒血流显像(CDFI)以及两者结合进行诊断检查。以患者的手术病理为诊断依据, 比较3种方法的诊断效果。结果:98例中有64例患者的96个乳腺结节病理结果为良性;34例患者的42个乳腺结节为恶性。患者病理检查良、恶性乳腺结节结果与CDFI、UE和CDFI+UE检查结果差异均无统计学意义(P>0.05), 3种诊断方法检查结果差异均无统计学意义(P>0.05)。其中, CDFI+UE的诊断敏感度为97.62%, UE、CDFI单用分别为83.33%、88.10%;CDFI+UE的特异度与诊断准确度分别为96.88%、97.10%, CDFI、UE单用分别为92.71%、91.30%与93.83%、92.03%。结论:CDFI、UE结合用于诊断乳腺肿瘤具有较高的诊断敏感性、特异性及准确性, 值得临床推广应用。

Application of the ultrasound elastography combined with color doppler flow imaging in the diagnosis of breast cancer

Objective:To evaluate the effects of ultrasound elastography combined with color doppler flow imaging in the diagnosis of breast cancer. Methods:The breast cancer(138 breast nodules) in 98 patients were detected by ultrasound elastography,color doppler flow imaging and ultrasound elastography combined with color doppler flow imaging. The diagnostic results of three methods were compared according to the pathology imaging. Results:The pathology results showed that 96 nodules in 64 patients were benign,42 nodules in 42 patients were malignant. The differences of benign and malignant breast nodules of patients between pathology results and CDFI,UE and CDFI+UE test results were not significant(P >0. 05). The diagnostic sensitivities of ultrasound elastography,color doppler flow imaging and ultrasound elastography combined with color doppler flow imaging were 83. 33%,88. 10% and 97. 62%, respectively. The specificities and diagnostic accuracy of ultrasound elastography,color doppler flow imaging and ultrasound elastography combined with color doppler flow imaging were 92. 71% &91. 30%,93. 83% &92. 03% and 96. 88% &97. 10%. Conclusions:The diagnostic sensitivity,specificity and accuracy of ultrasound elastography combined with color doppler flow imaging in the diagnosis of breast cancer are high,which is worthy of clinical application.
