Abstract
Objective To investigate the value of B DWI value in breast cancer .Methods 50 cases of patients with breast cancer by EPI‐DWI scan ,0~4 000 s/mm2 between 12 b values .In accordance with the single index model calculation value ADC (AD‐Chigh ,200s/mm2 <b is less than or equal to 4 000 s/mm2 ) and standard ADC (ADCstandard ,0s/mm2 <b is less than or equal to 4 000 s/mm2 ) low b value ADC (ADClow ) (B is less than or equal to 200 s/mm2 ) ,B;according to the double exponential model to calculate fast ADC(adcfast) slow ADC (adcslow ) and stADC proportion ;with conventional single exponential decay model of 800 s /mm2 of ADC values .All cases were confirmed by pathology ,were divided into benign group and malignant tumor group ,to com‐pare the value of these parameters in the differential diagnosis of tumors in the two groups .Results the difference of ADClow ,AD‐Chigh ,ADCstandard ,ADC ,ADCfast and traditional ADCslow in breast cancer were significant (P<0 .05) .The difference of ADCs‐low in breast benign and malignant tumors of the biggest .Conclusion when the b value in the larger range ,double exponential model can reflect the characteristics of more breast tumor tissue ,on behalf of inner cell molecular diffusion adcslow value in the differences between benign and malignant breast tumors ,this conclusion still need to large sample further validation .关键词
