How Radiologists Interpret Screening Mammographies May Vary By Technologist Performing The Exam

Tuesday, December 16, 2014
Diagnostic Imaging (12/16) reports that research published in Academic Radiology suggests that “how radiologists interpret screening mammographies varies substantially by the technologist performing the examination.” Investigators “found that the technologists had a statistically significant effect on the radiologists’ recall rate, sensitivity, specificity, and CDR for both SFM and FFDM. For PPV1, variability by technologist was observed for SFM but not for FFDM.” 

Readability Assessment of Internet-based Patient Education Materials Related to Mammography for Breast Cancer Screening

Tuesday, December 16, 2014
This research shows that the readability of internet-based patient education materials (IPEMs) regarding mammography for breast cancer screening is too difficult for the average woman. The mammography-related data concluded that IPEMS are written well above the recommended sixth grade level and more likely to reflect other IPEMs in diagnostic radiolog.

Adding DBT To Digital Screening Mammography May Help Classify Noncalcified Breast Lesions More Accurately

Monday, December 15, 2014
Aunt Minnie (12/15, Yee) reports that according to a study presented at the RSNA 2014 meeting, “adding digital breast tomosynthesis (DBT) to digital mammography for screening” may help classify “noncalcified breast lesions more accurately in the diagnostic setting.” Researchers arrived at that conclusion after reviewing “all diagnostic mammograms performed with tomosynthesis over a 30-month period, with year 1 spanning January 2012 to January 2013, year 2 covering January 2013 to January 2014, and a six-month period covering January to July 2014.” 

Women With A Mental Illness May Be Less Likely To Undergo Breast Cancer Screening

Friday, December 5, 2014
Research published in the BJPsych suggests that “women with a mental illness appear to be less likely to be screened for breast cancer.” Data on nearly “700,000 women with mental illness” were compared to data on nearly 21,500 women who did not have a mental illness. Investigators found that “the women with mental illness were much less likely than those without mental illness to undergo mammography screening for breast cancer.”
