CDFI、UE联合诊断乳腺结节及TNM分期效果观察

Effect of CDFI and UE in the diagnosis of breast nodules and TNM staging

目的探讨超声弹性成像技术(UE)与彩色多普勒超声技术(CDFI)联合用于乳腺结节良恶性临床鉴别及TNM分期诊断的价值。方法选取86例乳腺结节患者作为研究对象,均给予CDFI联合UE检查。以手术病理诊断结果作为“金标准”,回顾分析该种诊断方案的应用效能。结果86例患者中62例为良性病变,24例为恶性病变。良性组、恶性组CDFI检查血流分级及UE评分比较均有明显差异,且差异均有统计学意义(P<0.05)。TNM分期不同,患者UE评分、CDFI血流分级均明显不同,且差异有统计学意义(P<0.05)。CDFI联合UE检查用于恶性乳腺结节检查的敏感度高达95.83%,显著高于UE、CDFI检查的79.17%(P<0.05),诊断特异度、准确度对比均无显著差异(P>0.05)。结论CDFI和UE检查应用于乳腺结节良性、恶性临床鉴别诊断表现出较高效能,且能够为TNM分期评估提供可靠参考数据。

Objective To investigate the value of ultrasound elastography(UE)and color Doppler ultrasound(CDFI)in the differential diagnosis of benign and malignant breast nodules and TNM staging.Methods Eighty-six patients with breast nodules were selected as the research object,and all patients were given CDFI combined with UE examination.The results of surgical pathology were used as the“gold standard”to retrospectively analyze the application efficiency of this diagnostic scheme.Results Among the 86 cases,62 cases were benign and 24 cases were malignant.There were significant differences in CDFI blood flow grading and UE score between benign group and malignant group,and the differences were statistically significant(P<0.05).According to TNM stage,UE score and CDFI blood flow grade were significantly different(P<0.05).The sensitivity of CDFI combined with UE was 95.83%,which was significantly higher than that of UE and CDFI(79.17%)(P<0.05).There was no significant difference in diagnostic specificity and accuracy(P>0.05).Conclusion CDFI and UE have high efficiency in the differential diagnosis of benign and malignant breast nodules,and can provide reliable reference data for TNM staging.
