FFDM resulted in significantly higher cancer detection and recall rates than screen-film mammography in women 50–64 years old. The PPVs of FFDM and screen-film mammography were comparable. The results of this study suggest that FFDM can be safely implemented in breast cancer screening programs

The radioguided technique is as effective as the standard wire technique for localization and excision of nonpalpable breast cancer lesions and is somewhat faster and simpler to perform than wire localization

Combinations of BI-RADS lesion descriptors can predict the probability of malignancy for breast MRI masses but not for NMLE.
If our model is validated, masses with a low probability of malignancy may be eligible for short-interval follow-up rather than biopsy.
Further research focused on predictive features of NMLE is needed

The MR characteristics of lesions most likely to be seen with an ultrasound correlate were mass versus non-mass, increasing size, and increased level of suspicion of the lesion. Clip placement and follow-up imaging after ultrasound-guided biopsy that yields benign concordant results should be performed to detect cases in which the presumed ultrasound correlate is inaccurate to detect unsuspected false-negative biopsies

We found breast MRI to be a useful adjunctive tool when findings at conventional imaging were equivocal. Strict patient selection criteria should be used because of the high frequency of incidental lesions seen on MR images

Quantitative assessment of the type of contrast enhancement kinetic curve on breast DCE-MRI resulted in significantly higher diagnostic performance for establishing or excluding malignancy compared with assessment based on the standard qualitative method

Diffusion-weighted imaging is a potential resource as a coadjutant of MRI in the differentiation between benign and malignant lesions. Such imaging can be performed without a significant increase in examination time, especially because it can be done with lower b values
