Of 1215 women with elevated breast cancer risk who could, according to protocol guidelines, undergo breast MR imaging, only 57.9% agreed to participate
Claustrophobia was the most common reason (in 130 [25.4%] of 512 women) given for non-participation

Compared with osteopontin (OPN)-negative breast cancers, OPN-positive tumors were more likely to have calcifications, to be spiculated, to have pleomorphic calcifications, to be a triple-negative phenotype, and to be associated with axillary lymph node metastasis

In general, the breast US computer-aided diagnosis system appears to be effective across different patient populations, but further investigation is warranted

We found that 23.6% of cancers had a discordant interpretation in prospective independent double-reading examinations performed in a population-based mammography screening program that included dedicated as well as general radiologists

Fellowship training in breast imaging was the only radiologists' characteristic significantly associated with greater sensitivity and higher overall accuracy; however, fellowship-trained radiologists also had significantly higher false-positive rates

Radiologists without fellowship training in breast imaging significantly improved in their interpretation of screening mammograms as they gained clinical experience following residency, while radiologists who received fellowship training in breast imaging did not have this learning curve in clinical practice

The inclusion of similar images can have beneficial effects for many cases in which the status of a lesion is unclear, and it can improve the performance of radiologists in observer studies

Miglioretti et al and Elmore et al could determine the criteria that the 18 radiologists with highest interpretive performance used; all radiologists could be taught these criteria to benefit those with lower performance
