Breast cancer risk profiles differ in developing nations
July 1, 2014 -- Breast cancer incidence is rising all over the world, especially in developing countries, where its epidemiological features differ from those in Western countries, according to a study in the European Journal of Cancer that used North African countries as an example.
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.
Talks by radiologists can reduce patient anxiety over screening
May 27, 2014 -- Screening mammography is under intense scrutiny, with critics questioning its efficacy and calling attention to its harms -- including patient anxiety in the face of false positives. Direct and proactive education offered by mammographers can counter these questions, according to research presented at the recent American Roentgen Ray Society meeting.
Mary's Musings: Can big data add insight to breast screening?
May 22, 2014 -- Dr. Mary Morrison Saltz enters the fray over breast screening in this month's column, in which she addresses the uncertainty over whether screening mammography is effective and how it might be improved. She also makes a surprising confession of her own.
Uterine artery embolization (UAE) in the UAE
May 21, 2014 -- Since it was first introduced in the United Arab Emirates (UAE) several years ago, uterine artery embolization has become a popular procedure for many young women who have symptomatic uterine fibroids. In this article, the team that introduced UAE to the UAE describes the procedure and its advantages.
Study: Do fetal anatomy US scans earlier in obese women
May 19, 2014 -- Morbidly obese pregnant women face a greater risk of poor outcomes and can be difficult to image adequately on prenatal ultrasound. For that reason, fetal anatomy ultrasound scans should be performed earlier in these women, with the optimal gestational age for scans dropping as body mass index goes up.
Moments in Radiology History: Part 15 -- Mammography's roots
May 9, 2014 -- Today's debate over the value of breast screening is nothing new. In fact, controversy has dogged mammography almost since the technique was invented. In his latest installment of Moments in Radiology History, Otha Linton traces the mammography debate through the career of its earliest proponent, Dr. Robert L. Egan.
ARRS: Patients overestimate mammography radiation danger
May 5, 2014 -- Women overestimate the amount of radiation they receive from mammography exams, which could lead them to avoid screening, according to data presented at the American Roentgen Ray Society (ARRS) annual meeting in San Diego.
ARRS: Diagnostic breast tomo reduces need for US, biopsies
May 5, 2014 -- Using breast tomosynthesis in diagnostic workup -- specifically, with one- or two-view focal asymmetries found at screening mammography -- reduces ultrasound use and leads to fewer biopsies compared to diagnostic mammography alone, according to research presented at the American Roentgen Ray Society (ARRS) meeting in San Diego.
Brassieres help cut chest CT radiation dose
May 5, 2014 -- Wearing a bra during a chest CT scan can significantly reduce dose to radiosensitive tissues by holding breast tissue within the lower-dose region created by tube-current modulation techniques, concludes a new study in the May issue of the American Journal of Roentgenology.
ASBrS: For node-positive breast cancer, radiotherapy is best
May 5, 2014 -- Lymph node axillary radiotherapy is associated with significantly fewer complications than traditional axillary lymph node removal, and it may be poised to become the standard of care, according to research presented on April 30 at the American Society of Breast Surgeons (ASBrS) meeting in Las Vegas.
