Abstract：Objective To investigate the evaluation of non-mass breast cancer(NMBC)by X-ray molybdenum target com-bined with magnetic resonance imaging-diffusion weighted imaging(MRI-DWI).Methods 110 highly suspected NMBC pa-tients were selected as the study subjects.All patients underwent X-ray molybdenum target,MRI-DWI,and breast biopsy exami-nations.The results of breast biopsy were used as the gold standard to explore the evaluation and analysis of X-ray molybdenum target combined with MRI-DWI for NMBC.Results Among 110 highly suspected NMBC patients diagnosed by breast puncture biopsy,90 cases(81.82%)were NMBC patients.20 were non NMBC patients(19.18%).The Kappa values of consistency be-tween mammography and MRI-DWI in the diagnosis of NMBC and the gold standard were 0.572 and 0.622,respectively,and the consistency was general.The Kappa value of mammography combined with MRI-DWI in the diagnosis of NMBC and the gold stan-dard was 0.809,and the consistency was good.As the sensitivity and accuracy of the three groups were compared,the results were as follows:mammography combined with MRI-DWI>MRI-DWI>mammography(P<0.05).The proportion of microcalcifica-tion and structural distortion in NMBC group was significantly higher than that in non-NMBC group.ADC value was lower than that of non-NMBC group(P<0.05).Conclusion The combination of X-ray molybdenum target and MRI-DWI has a high effi-cacy in evaluating NMBC,which can provide reference for the clinical diagnosis and treatment of NMBC.
