Volume trumps experience when reading mammograms June 30, 2014 -- When reading screening mammograms, the number of studies read per year is more important in determining the ability to detect cancer than the experience of the reader, according to a new study in the Journal of Medical Imaging that compared U.S. and Australian radiologists.
Native American, rural women have less access to breast MRI June 27, 2014 -- Most U.S. women have relatively easy access to mammography and breast ultrasound, but breast MRI presents a greater challenge, especially for Native American women and those in rural areas, according to a new study published online in the Journal of the American College of Radiology.
4-scan PET/MRI exams improve breast imaging June 25, 2014 -- Austrian researchers added PET/CT to a package of three MRI sequences to create fused PET/MR images, which they found aided in the differentiation of suspicious breast lesions, according to a new study published online in Clinical Cancer Research.
JAMA: Adding tomo to mammography finds more cancer June 24, 2014 -- Adding digital breast tomosynthesis to mammography screening boosts the detection of invasive cancer by more than a third compared to mammography alone while reducing the number of false positives by 15%, according to a study in the June 25 issue of the Journal of the American Medical Association.
DBT not only finds more cancers, but more invasive ones June 18, 2014 -- In community practice, digital breast tomosynthesis (DBT) performed better than conventional 2D mammography, reducing recall rates, increasing overall cancer detection, and increasing the detection of invasive cancer, according to research published online June 11 in the American Journal of Roentgenology.
Breast tomosynthesis adoption uneven across the U.S. June 17, 2014 -- When used with digital mammography, digital breast tomosynthesis has been shown to improve the diagnostic accuracy of breast cancer screening and diagnosis. But exactly how and where is it being used in the U.S.? Researchers investigated this question and presented their findings in the June issue of the Journal of the American College of Radiology.
Synthesized 2D images dramatically reduce DBT radiation dose June 13, 2014 -- Breast imagers reading 2D images synthetically reconstructed from digital breast tomosynthesis (DBT) data had comparable performance to those reading conventional 2D mammography and DBT scans for breast cancer screening, while exposing women to less radiation dose, according to a study published in the June issue of Radiology.
Cancer: Screening mammo cuts incidence of late-stage cancer June 12, 2014 -- Over the past 30 years, screening mammography has not only identified more early-stage breast cancer, it decreased the incidence of late-stage disease by more than a third, according to a study published online in the journal Cancer.
MDCT: Kalender offers update on breast CT June 12, 2014 -- Clinical trials for a high-resolution breast CT scanner will begin in Germany in early 2015, according to a talk by Willi Kalender, PhD, at the International Symposium on Multidetector-Row CT (MDCT). The hope is that the technology will outperform full-field digital mammography and breast tomosynthesis at equivalent dose levels.
Incidental findings on CT predict cardiovascular disease risk May 28, 2014 -- Incidental findings on routine chest CT exams can be used to accurately predict risk for serious cardiovascular events, according to a just-published study in Radiology. Such findings could be preclinical signs of atherosclerosis and support an imaging-based model for risk prediction.
