Objective To investigate the value of breast MRI-abbreviated protocol(BMRI-AP)compared with full field digital mammography(FFDM)and breast MRI-full diagnostic protocol(BMRI-FDP)in the diagnosis of early breast cancer with non-calcified.Methods A total of 95 cases patients with early breast cancer with non-calcified(the longest diameter of the lesion≤2 cm,regardless of the size of the carcinoma in situ)were retrospectively included.Clinical,pathological and imaging data of all patients were collected.All patients underwent FFDM and MRI scanning,and three examination regimens,including FFDM,BMRI-AP,BMRI-FDP,were further obtained.Classification was performed according to the breast imaging reporting and data system(BI-RADS)classification standard(fifth edition)developed by American College of Radiology(ACR),and pathological results were taken as the standard.The diagnostic efficacy for early breast cancer with non-calcified were compared among the different three imaging methods.Results The diagnostic accuracy of FFDM,BMRI-AP and BMRI-FDP for early breast cancer with non-calcified was 76.84%,93.68%and 95.79%,respectively,with statistically significant difference among three groups(χ2=20.558,P<0.001).The median(quartile distance)of BMRI-AP and BMRI-FDP scanning time were 478(5)s and 926(13)s,respectively,with statistically significant difference between the two groups(Z=-11.912,P<0.001).Conclusion The diagnostic accuracy of BMRI-AP is significantly better than that of FFDM and similar to that of BMRI-FDP for early breast cancer with non-calcified.In addition,BMRI-AP can significantly shorten the scanning time without reducing the diagnostic accuracy,which is expected to become a new breast cancer screening method.
