Analysis of contrast enhanced ultrasound and pathological result of breast tumors
Abstract：Objective To explore the value of contrast enhanced ultrasound (CEUS) breast lesions in differ-ential diagnosis .Methods Making the results of the pathology test as standard , an CEUS process analysis of breast <br> lesions was performed in 261 patients who were diagnosed as breast tumor by 2-dimensional CEUS before operation and the parameter value of Time-Intensity Curve was gotten by SonoLiver software , and the results obtained were com-pared with the result of the pathology test after operation (benign 169 cases/186 lesions, malignant 92 cases/121 le-sions).Results The CEUS of malignant tumor showed that lesions had an early rapid , non-uniform, high enhance-ment and peripheral radial enhancement .The benign tumor showed that lesions had an early slow , uniform, low or no enhancement , and no peripheral radial enhancement .Significant decrease of length width ratio of breast lesions after radiography maybe suggest a malignant tumor .There was a significant difference in the ROI mode intensity between benign and malignant lesions ( P<0.01 ) .Comparison of the results between radiography and pathology shaved , in 181 benign lesions , 166 were correct on CEUS , 20 were misdiagnosed as malignant , and in 121 malignant lesions , 103 were correct on CEUS , 18 were misdiagnosed as benign .For diagnosis of malignant tumor , CEUS showed the sensitivity was 85.1%, specificity was 89.2%and accuracy was 87.6%.Conclusion CEUS can observe dynami-cally the situation of microvascular blood perfusion in breast lesions , and application of SonoLiver software can ana-lyze lesions quantitatively and improve the levels of differential diagnosis of benign and malignant breast tumors .
