Abstract:
ObjectiveTo investigate the accuracy of automated breast volume scanning (ABVS) for the measurement of breast tumor size.MethodsSixty-two breast tumors in 59 patients were included in this study and were examined using conventional ultrasound and ABVS to measure the maximal diameters of the tumors. And the measurement results were compared with the pathological maximal diameters.Results There were 21 malignant and 41 benign tumors according to histopathological evaluation. There were no signifi cant differences between the maximal diameters on ABVS and on pathological measurements for both benign tumors and malignant tumors (Z=1.761, 0.262,P=0.078, 0.794). However, for malignant tumors, the maximal diameters on conventional ultrasound were significantly smaller than those on pathological measurements (Z=3.743,P=0.000). For benign tumors, the maximal diameters on conventional ultrasound were similar with those on pathological measurements (Z=1.935,P=0.053). The measurement values of conventional ultrasound and ABVS were both positively correlated with those on pathological values (r=0.935, 0.964,r=0.870, 0.964). And the correlation coeffi cients between ABVS and pathological measurement values were higher than those between conventional ultrasound and pathological measurement values for both benign and malignant tumors. ConclusionABVS can assess the size of breast tumor more accurately than conventional ultrasound, especially for the malignant tumors.
