弹性应变率比值与BI-RADS标准鉴别诊断乳腺肿块的对比研究
Comparative study of elastic strain ratio and BI-RADS standard in differential diagnosis of breast lesions
摘要
Abstract
Objective To investigate the optimal points of elastic strain ratio ( SR) in diagnosis of benign and ma-lignant breast lesions and compare the diagnostic value of SR with BI-RADS standard. Methods 94 patients with 101 breast lesions were included in the study. The lesions were scored with BI-RADS standard and SR respective-ly. The pathologic diagnosis was the gold standard. Constructed the receiver operating characteristic ( ROC) curve and determined the optimal points of SR in the diagnosis of malignant breast lesions. Compared the diagnostic value of SR with BI-RADS standard. Results The area under the curve of SR was 0. 933,the cut-off point for strain ratio was 3. 03. The strain ratio of benign group was (1. 96 ± 0. 88),the malignant group was (4. 74 ± 2. 22),there was significant difference between two groups(P<0. 01). The sensitivity,specificity,accuracy,positive predictive value , negative predictive value of strain ratio and Conventional ultrasound were 92. 3%,88. 7%,90. 1%,83. 7%, 94. 8% and 71. 8%,87. 1%,81. 2%,77. 8%,83. 1%. Sensitivity of strain ratio was better than BI-RADS standard (P<0. 05). Conclusion As a semi quantitative method,SR is more sensitive than BI-RADS standard. It can im-prove the detection rate of malignant breast lesions.关键词
