CR, DR breast cancer screening performance comparable
June 14, 2013 -- Radiologists reading breast screening studies had comparable performance regardless of whether the images were acquired with computed radiography (CR) or digital radiography (DR) mammography systems, according to a Belgian study published online in European Radiology. Still, DR delivered a lower radiation dose than CR.
Radium-223 dichloride is focus of SNMMI Image of the Year
June 11, 2013 -- VANCOUVER - An FDG-PET/CT scan illustrating the effectiveness of radium-223 dichloride in treating bone metastases in breast cancer patients with bone-dominant disease has been selected as the Image of the Year at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.
Shear-wave elastography boosts second-look breast US
June 6, 2013 -- Adding shear-wave elastography to a second-look breast ultrasound study performed after dynamic contrast-enhanced MRI can detect nearly a third more cancers than B-mode ultrasound alone, Ohio researchers have found.
Reading volume affects mammography performance
June 6, 2013 -- Radiologists who read fewer than 1,000 mammography studies per year may have worse diagnostic accuracy than those who read more, according to a new study published online June 4 in Radiology. The performance threshold is more than twice what is required in the U.S. for radiologists who read mammograms.
CAD for breast MRI improves sensitivity; accuracy not so much
May 24, 2013 -- Computer-aided detection (CAD) technology improves sensitivity in breast MRI for both experienced and novice readers, but it does not significantly advance overall accuracy, according to a study published in the June issue of the American Journal of Roentgenology.
AJR: DBT reduces screening recall rates by 37%
May 22, 2013 -- Digital breast tomosynthesis (DBT) when used as a screening tool for breast cancer reduces recall rates by 37% and increases the detection of invasive cancers by 54%, according to a new study published online May 22 in the American Journal of Roentgenology.
Women in their 40s reluctant to give up breast screening
May 17, 2013 -- In a study that confirms recent findings, researchers from Johns Hopkins University found that mammography screening rates have changed little among women in their 40s despite guideline changes by the U.S. Preventive Services Task Force. Study results were published May 15 in the Journal of General Internal Medicine.
CR mammography lags DR, film-screen in cancer detection
May 14, 2013 -- Canadian researchers performing mammography with a computed radiography (CR) system saw lower breast cancer detection rates compared to analog film-screen mammography or a system based on flat-panel digital radiography (DR). Results were published online May 14 in Radiology.
KLAS: Demand for breast tomosynthesis is increasing
May 14, 2013 -- The demand for digital breast tomosynthesis systems is increasing, according to a new report released on May 14 by market research firm KLAS. When imaging providers were asked which technology they would choose if they could start over, 62% said tomosynthesis.
Volumetric MR images boost cervical cancer treatment planning
May 13, 2013 -- Three-dimensional volumetric MR images of cervical disease yield a bounty of critical information, enabling precise planning of brachytherapy for residual tumors, according to researchers from St. Joseph's Hospital and Medical Center in Phoenix.
California's breast density notification law -- 1 month in
May 9, 2013 -- It's been just over 30 days since California's version of breast density notification legislation went into effect. How is the law affecting clinical practice in the state's breast centers? Although they are complying, many breast imagers are skeptical of its value.
ASBS: Breast MRI helps assess patient prognosis
May 8, 2013 -- MRI evaluation following breast cancer diagnosis can improve a woman's long-term prognosis, as the modality is able to detect lymph-node metastases associated with poorer outcomes, according to research presented on May 3 at the American Society of Breast Surgeons (ASBS) annual meeting in Chicago.
Breast MRI changes cancer treatment in many women over 60
May 3, 2013 -- A new study led by Dr. Stamatia Destounis found that women older than 60 years saw changes to their initial cancer treatment plan approximately 50% of the time after undergoing MRI to determine the extent of disease.
Kopans: Breast cancer overdiagnosis grossly exaggerated
April 30, 2013 -- In this Second Opinion article, breast imaging expert Dr. Daniel Kopans offers his rebuttal of a study published last November in the New England Journal of Medicine, which raised questions about the value of screening mammography and claimed that a third of detected breast cancers represent "overdiagnosis."
SAVI breast brachytherapy produces good 4-year outcomes
April 26, 2013 -- Patients who received breast brachytherapy delivered with a strut-based applicator had low recurrence rates and minimal toxicities four years after treatment, according to a presentation at last week's American Brachytherapy Society meeting.
Adding 3D breast tomo to mammography finds more cancers
April 25, 2013 -- Using 3D digital breast tomosynthesis with conventional 2D mammography finds 50% more cancers than 2D imaging alone and also reduces the false-positive rate, according to a new study published online April 25 in Lancet Oncology.
MRI adds to cancer detection in women with breast implants
April 25, 2013 -- When used as an adjunct to mammography and ultrasound, MRI can find additional cancers and provide more detail about their location in patients with breast implants, according to a study from Memorial Sloan-Kettering Cancer Center.
Changes in breast density point to tamoxifen's effectiveness
April 22, 2013 -- If women being treated with tamoxifen for breast cancer see their breast density drop, they may have a 50% lower risk of dying from the disease, according to a new study by Swedish researchers published online April 22 in the Journal of Clinical Oncology.
Are women ignoring USPSTF's breast screening advice?
April 19, 2013 -- Younger women in the U.S. apparently haven't heeded recent advice on mammography screening by the U.S. Preventive Services Task Force (USPSTF). A study published April 19 in Cancer found that screening rates have remained steady for women ages 40 to 49 after the USPSTF's 2009 guideline change.
ARRS: Breast tomo increases cancer detection by 11%
April 19, 2013 -- The addition of digital breast tomosynthesis to a screening mammogram increased the rate of breast cancer detection by 11%, according to one of several studies on 3D mammography presented this week at the American Roentgen Ray Society (ARRS) meeting in Washington, DC.
Breast CAD's effectiveness questioned again in new study
April 15, 2013 -- Dr. Joshua Fenton of the University of California, Davis has emerged as one of the most prominent skeptics of computer-aided detection (CAD) technology for breast screening. Fenton is again questioning CAD's effectiveness in a new study published online April 15 in the Annals of Internal Medicine.
