Abstract:
Objective To investigate the value of T2 mapping sequence combined with apparent diffusion coefficient(ADC)values in identifying benign and malignant breast lesions.Methods Ninety-two patients with breast mass were retrospectively selected,all patients received MRI examination,T2 mapping sequence and ADC values were selected for image analysis,and all patients underwent surgical biopsy and pathological diagnosis,the clinical value of T2 mapping sequence combined with ADC values in differential diagnosis of benign and malignant breast lesions was observed.Results After pathological examination,52 patients were diagnosed as malignant breast lesions and the remaining 40 were diagnosed as benign breast lesions.Among 52 patients with malignant lesions,51 were diag-nosed as malignant and 1 was diagnosed as benign by ADC values.Among the 40 cases of benign lesions,16 were diagnosed as malig-nant and 24 were diagnosed as benign by ADC values.The difference between the mean T2 values of benign breast lesions and malig-nant breast lesions was not significant(P＞0.05);but the coefficient of variation(CV)of T2 values of malignant breast lesions was significantly higher than that of benign breast lesions,and the difference was significant(P＜0.05),and the diagnostic efficacy of T2 mapping and ADC value single examination was lower than that of the combined examination(P＜0.05).Conclusion T2 mapping sequence and ADC value in MRI have the ability to diagnose and distinguish benign and malignant breast,especially the value of the joint application of the two is more prominent,improve the diagnostic accuracy,sensitivity and specificity,and can provide more accurate reference information for clinical practice,which is worth popularizing.
