Dear AuntMinnie Member,
A new study has confirmed previous research on the effectiveness of digital breast tomosynthesis (DBT), showing that the technology when used with digital mammography for breast cancer screening has higher cancer detection rates and lower recall rates.
But the new study also raised a red flag about DBT: Researchers found that the combination of DBT and digital mammography for screening could result in higher rates of short-term follow-up to investigate suspicious BI-RADS 3 lesions.
Although the difference wasn't statistically significant, it could signify a learning curve with respect to DBT adoption. Learn more by clicking here, or visit our Women's Imaging Community at women.auntminnie.com.
Repeat fetal ultrasound
While we're on the subject of imaging studies that have to be repeated, visit our Ultrasound Community for an article that examines whether it's a good idea to repeat screening fetal ultrasound exams if the original study is inconclusive.
Researchers from Yale University looked at more than 1,500 ultrasound exams that were performed because the original scan was judged to have incomplete visualization of fetal anatomy. They found that only one in 200 of such scans would eventually identify an abnormal body part -- raising the question of whether they should be performed at all.

PiB-PET for meningioma
Finally, be sure to visit our Molecular Imaging Community for this study from RSNA 2016 on the use of the radiopharmaceutical carbon-11-labeled Pittsburgh Compound B (PiB) with PET to distinguish meningiomas from other intracranial tumors.
