Abstract:
Objective To compare the diagnostic efficacy of digital mammography,ultrasonography and MRI for breast non-mass enhancement (NME).Methods The digital mammography,ultrasonography and MRI data of 1 1 6 patients with 123 NME lesions on MRI were analyzed retrospectively.Results 99 lesions were malignant and 24 lesions were benign according to the pathologiacl result.The sensitivity of digital mammography,ultrasonography and MRI was 72.73%,65.66%,and 84.85%,respectively;The specificity was 66.67%,79.1 7%,and 79.1 7%,respectively;The accuracy was 71.54%,68.29%,and 83.74%,respectively;The positive pretictive value was 90.00%,92.86%,and 94.88%,respectively;The negative pretictive value was 37.21%,35.85%,and 55.88%,respectively.The sensitivity,specificity,accuracy,positive pretictive value and negative pretictive value of MRI were obviously higher than those of digital mammography and ultrasonography (P <0.05).The difference between the combinations and MRI alone were no statistically significant.Conclusion MRI have better diagnostic value,and could be used as the first choice examination for breast NME lesions.
