Diagnostic value of MRI in benign and malignant breast lesions / 实用放射学杂志

ABSTRACT

Objective To investigate the value of qualitative and quantitative parameters of MRI on diagnosis of benign and malig-nant breast lesions.Methods Patients were scanned with MRI who were confirmed as breast lesions verified by histopathology,and the time-signal curve(TIC),Slopemax ,the apparent diffusion coefficient values (ADC)were deduced.Results There were 24 benign and 11 malignant lesions.Features of benign lesions were shown as followThe TIC type wasⅠmostly 91.7%,Slopemax was 0.65 %/s,the ADC values was 1.31×10 -3 mm2/s.Features of malignant lesions were shown as followThe TIC type were Ⅱ and Ⅲ mostly (100%), Slopemax was 1.63 %/s,the ADC values was 1.06 ×10 -3 mm2/s.Conclusion Types of TIC,Slopemax ,the ADC values of MRI are valuable in the diagnosis of benign and malignant breast lesions,integrated functional parameters are better than an individual param-eters in that they can improve the accuracy of diagnosis.
