RESULTS:
The dominant morphologic appearance was a non-mass lesion with segmental and clumped or heterogeneous enhancement. The pure ductal carcinoma in situ lesions exhibited variable enhancement patterns consisting of persistent (34.3%), plateau (52.2%), and washout (13.4%) curves. The mean initial enhancement slope (p < 0.005) and time to peak enhancement (p < 0.05) correlated with MRI lesion type, and time to peak enhancement (p < 0.05) correlated with the sonographic findings. No statistically significant correlations were observed between the kinetic characteristics and histopathologic factors or mammographic findings (p > 0.05).
CONCLUSION:
Non-mass lesions and plateau curve enhancement were the dominant MRI findings of pure ductal carcinoma in situ. The lesions with mass appearance at MRI had more suspicious kinetic characteristics than did non-mass lesions

RESULTS:
For each radiologist, the mean reading time for FFDM with digitized priors was significantly shorter in length in comparison with the mean reading time calculated for interpreting FFDM using analog film priors. The differences in times recorded between digitized analog versus analog ranged from 11.31 to 74.18 seconds. The reading times for the four readers ranged from 17.32 to 185.94 seconds, with a mean of 58.56 seconds when using analog film prior mammograms. When using digitized analog prior mammograms, the reading times for the four readers ranged from 11.32 to 109.11 seconds with a mean of 39.76 seconds. The average difference in reading time was calculated to be 18.80 seconds, showing that there is a 32% increase in interpretation speed when using a digitized prior analog for comparison studies as opposed to an analog prior.
CONCLUSION:
There is a statistically significant 32.1% average improvement in interpretation time when FFDM screening mammograms use digitized analog comparison mammograms than if FFDM is interpreted with the original analog film mammograms. This should allow more FFDMs to be interpreted in the same amount of time if digitized prior analog mammograms are used

RESULTS:
Mammography showed 53 lesions had calcifications without (n = 39) or with (n = 14) a mass. Calcifications of intermediate concern or associated with higher probability of malignancy were found more frequently in mucocele-like tumors associated with ADH or malignancy than in pure mucocele-like tumors (92.3% vs 62.9%, p = 0.019). At ultrasound, 69 of the mucocele-like tumors (95.8%) were seen as a cystic mass. Cysts with thick septations, clustered cysts, and complex masses were more frequently seen in mucocele-like tumors associated with ADH or malignancy (89.7% vs 32.5%, p < 0.001). The positive predictive value for BI-RADS category 4 was 13.3% (95% CI, 6.9–24.2%) and was 50% for BI-RADS category 5 (95% CI, 15–85%).
CONCLUSION:
Mucocele-like tumors associated with ADH or malignancy were more frequently seen as clustered cysts, cysts with thick septations, and complex masses associated with calcifications of intermediate concern or higher probability of malignancy. BI-RADS can be used in the management of mucocele-like tumors.
