摘　　要：目的:研究血流阻力指数(RI)用于乳腺良恶性肿块鉴别诊断的价值。方法:以术前行彩色多普勒血流显像(CDFI)检查并测定RI值,且有术后病理诊断结果为纳入标准,回顾性分析2021年8月至12月共145例患者的临床资料,共包括153个病灶。对比分析良性组(n=50)和恶性组(n=103)RI均值的差异,探讨RI临界值设定对鉴别诊断的影响。结果:良性组RI均值为0.62±0.09(范围:0.46~0.88),恶性组RI均值为0.78±0.10(范围:0.48~1.00),显著高于良性组(P<0.01)。以ROC曲线确定RI最佳临界值,最终以RI值≥0.70鉴别良恶性的敏感度为85.4%,特异度为78.0%。结论:CDFI测定RI值对乳腺疾病的诊断与鉴别诊断有重要价值,肿块内高RI值对提示乳腺恶性肿瘤有一定的临床意义。Objective:To evaluate the diagnostic efficiency of resistance index(RI)in benign and malignant breast lesions.Methods:Color Doppler flow imaging(CDFI)based RI measurement results of breast lesions were studied and compared with postoperative pathological results.Clinical data of 145 patients with 153 breast lesions were also retrospectively analyzed from August to December 2021.RI values of the benign group(n=50)and malignant group(n=103)were compared,and the cut‑off value of RI was explored for differential diagnosis.Results:The mean value of RI in benign group and malignant group were 0.62±0.09(range:0.46‑0.88)and 0.78±0.10(range:0.48‑1.00),respectively(P<0.01).The ROC curve was used to determine the optimal cut‑off value of RI.The sensitivity and specificity were 85.4%and 78.0%if RI was more than 0.70.Conclusion:CDFI‑based RI measurement could be used in the diagnosis and differential diagnosis of breast diseases.Breast tumors with high RI values tended to be malignant.
