Variables that minimized procedure duration were number of image acquisitions, number of patient insertions or removals from the magnet, and assistance of a breast imaging fellow-in-training. No patient-related or target-related variables impacted procedure time

Differences between screen-film mammography and FFDM in compression force and indicated compressed breast thickness were small. On average, FFDM had 22% lower mean glandular dose than screen-film mammography per acquired view, with sizeable variations in average FFDM doses by manufacturer

MR-directed ultrasound of MRI-detected lesions was useful for decision making as part of the diagnostic workup. Malignant lesions were likely to have an ultrasound correlate, especially when they presented as masses on MRI. However, the sonographic findings of these lesions were often subtle, and careful scanning technique was needed for successful MRI–ultrasound correlation

(Ed..) this validates studies from Korea and Italy, published in Europe which showed that an US correlate was strongly associated with subsequent outcome of malignancy

UCSF PAPER:
Solitary dilated duct is a rare mammographic finding, this series being the largest reported to date. Although few cases are studied, solitary dilated duct appears to have a greater than 2% likelihood of malignancy, sufficiently high to suggest that a suspicious (BI-RADS 4a) assessment may be appropriate

Ed... currently this is in the BIRADS lexicon as a benign finding. Our data suggest otherwise, but we await validation in a follow up series

We show that some combinations of digital mammography acquisition and display systems can lead to clinically significant over- or underestimation of lesion size in magnification mode. This phenomenon can occur even with acquisition and display systems from the same manufacturer. Thus, the accuracy of lesion size in each magnification mode should be a routine QC acceptance test performed on each digital mammography acquisition–display system combination

Sonographic classification of axillary lymph nodes is effective for predicting the presence of metastases to avoid sentinel node biopsy or to reduce unsuccessful lymphatic mapping during sentinel node biopsy
