Applying CAD twice to DBT improves performance at lower dose February 23, 2015 -- Researchers from the University of Michigan have developed a new double-barreled approach to computer-aided detection (CAD) that uses two separate CAD algorithms on digital breast tomosynthesis (DBT) exams. They believe the technique enables a high level of sensitivity with lower radiation dose.
Info on 'overdiagnosis' saps interest in breast screening February 19, 2015 -- Giving women more information about the negative aspects of mammography, such as overdiagnosis, makes them less inclined to want breast screening, according to a new Australian study published online February 17 in the Lancet.
Breast MR useful for assessing BI-RADS 4 lesions February 19, 2015 -- A new study published in the February issue of Radiology found that breast MR is useful for working up suspicious lesions classified as BI-RADS 4 at mammography or ultrasound -- and, in fact, can help avoid 92% of unnecessary biopsies.
Study finds decline in mammo rates after 2009 USPSTF change February 13, 2015 -- A new study published online February 9 in the Journal of Clinical Oncology found that mammography screening rates declined after the 2009 publication of controversial screening guidelines by the U.S. Preventive Services Task Force (USPSTF).
NEJM: Are breast density notification laws actually helpful? February 12, 2015 -- Twenty-one states have passed laws requiring women to be notified if their breast tissue is dense on mammography. But are the laws actually helpful? It's unclear, according to a perspective article published in the February 12 issue of the New England Journal of Medicine.
How interventional radiologists can make childbirth safer February 12, 2015 -- Traumatic vaginal deliveries, cesarean sections, and invasive placenta conditions can result in excessive bleeding and hysterectomy, and may be life-threatening for women, but innovative interventional radiology treatments are making childbirth safer.
Koning positions breast CT scanner as 1-stop diagnostic shop February 11, 2015 -- With approval from the U.S. Food and Drug Administration now in hand for its breast CT scanner, Koning plans to market the 3D system as the ultimate one-stop diagnostic workup tool. Breast screening applications will have to wait, however, pending further study.
How does breast tomosynthesis affect screening recall rates? January 30, 2015 -- Data from digital breast tomosynthesis (DBT) studies dominated the recent RSNA 2014 meeting, with a special emphasis placed on how the technology affects screening recall rates. For example, one study explored how radiologists' experience might affect recall rates with DBT, while another investigated how DBT could affect recall rates in women undergoing baseline breast cancer screening.
Adding MBI to mammography finds more cancers in dense tissue January 27, 2015 -- Adding molecular breast imaging (MBI) to conventional mammography finds more cancers in women with dense breast tissue -- and at acceptable radiation doses for screening, according to a new study published in the American Journal of Roentgenology.
JAMA: Breast cancer diagnosis and survival vary by race January 16, 2015 -- Race and ethnicity influence the likelihood that women in the U.S. will receive an early diagnosis of breast cancer, as well as their survival after stage I diagnosis, according to a study published in the new issue of the Journal of the American Medical Association.
