Abstract:
Objective To compare the value of automatic breast volume scanner (ABVS) with enhanced magnetic resonance imaging(MRI) in the diagnosis of breast masses.Methods Seventy-four patients with 80 breast masses underwent preoperative ultrasound examinations including ABVS and MRI.The values of ABVS and MRI in the diagnosis of breast masses were comparatively analyzed.Results Among the 80 breast masses that were surgically removed,37 masses were benign and 43 masses were malignant.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of ABVSin the diagnosis of breast malignant masses were 94.6％,79.1％,86.3％,79.5％ and 94.4％,respectively,those of MRI were 94.6 ％,86.0 ％,90.0 ％,85.4 ％ and 94.9 ％,respectively,and those of the combination of ABVS and MRI were 94.6％,93.0％,93.8％,92.1％,and 95.2％,respectively.The sensitivity and specificity were not significant difference between ABVS and MRI in the diagnosis of breast malignant masses(P ＞0.05).The specificity of the combination ABVS and MRI in the diagnosis of breast malignant masses were significantly higher than that of ABVS (x2 =4.17,P =0.04).The sensitivity,specificity and accuracy of convergence sign in the diagnosis of breast malignant masses were 64.9 ％,97.7 ％ and 82.5 ％,respectively.Conclusions ABVS and MRI are both valuable in the diagnosis of breast masses,and the combination of ABVS and MRI is the most valuable due to high specificity.
