Local strain ratio of ultrasound real-time tissue elastography in diagnosis of benign and malignant breast tumors
摘要
Abstract
Objective To analyze and investigate the diagnostic performances of local strain ratio (LSR) of ultrasound real-time tissue elastography in differentiating benign and malignant breast tumors.Methods 97 breast tumor patients with 122 lesions were examined by ultrasound real-time tissue elastography to measure the local strain rate.With the pathological types by biopsy as references,the differences between the patients with benign and malignant tumors were compared.The operating characteristic curve of the local strain ratio parameters were plotted,and the area under the curve was calculated.The sensitivity and specificity in distinguishing benign and malignant breast tumors were calculated.Results The local strain ratio was (23.87±6.92) in the benign group,and was (71.32±14.56) the malignant group.The AUC of the LSR was 0.909,and the 95％ CI 0.854-0.965 (P ＜ 0.05).Conclusion The utilization of local strain rate in the differential diagnosis of benign and malignant breast tumors is of potential diagnostic value.关键词
