Were any of you able to attend American Roentgen Ray Society (ARRS) this week in Vancouver? If so, we hope you took the time to visit us at our booth. There have been a number of interesting studies presented at this year’s meeting the majority of this week’s top 5 news stories will be coming from things we learned at ARRS this year.
Radiologists Feel Less Knowledgeable on Health Policy Issues
Diagnostic Imaging | April 30, 2012
Radiologists believe they are less competent than other physicians when it comes to healthcare knowledge including: patient imaging costs and patient safety; areas where one would think radiologists would be experts. Also, when it comes to business principles radiologists feel even less knowledgeable. This is according to a study presented at ARRS by researchers at Northwestern University. The survey answers were given on a scale of 0-5
o No knowledge = 0
o Trace knowledge = 1
o Below competent = 2
o Competent = 3
o More than competent = 4
o Highly competent = 5
ARRS: CT radiation far less risky than underlying disease
Aunt Minnie | May 1, 2012
There has been much concern regarding radiation from CT scans raising cancer risks. A new study presented at ARRS has determined that the benefit of receiving the CT scan far outweigh the risks of developing cancer later on. Compared to the diseases which most patients are screened for the risk of death from the initial ailment outweighs the risk of dying from cancer caused by CT 35 to 1. It is worth it to get the CT and be treated then to not know the diagnosis and die.
JAMA paper reignites debate over APBI treatment
Aunt Minnie| May 1, 2012
The debate over the effectiveness of breast cancer treatment with accelerated partial-breast irradiation (APBI) brachytherapy has resurfaced with the publication of a paper critical of the technology in the May 1 issue of the Journal of the American Medical Association. The paper states that women treated with APBI had higher mastectomy and complication rates compared to those treated with whole-breast irradiation, the standard of care. There are flaws in the study which critics say should discount the study.
ARRS: Digital tomo cuts breast exam recall rates by 40%
Aunt Minnie |May 3, 2012
Adding digital breast tomosynthesis (DBT) to a screening mammography exam reduced recall rates for patients by 40% at Yale-New Haven Hospital. Twenty-five percent of this group had the combined DBT and 2D mammography exam, and the remainder had a conventional digital mammography screening exam. The recall rate was 6.6% for the patients who had the combined exam, compared with 11.1% for those who only had a routine screening exam. Fewer recalls means fewer additional breast imaging views, which is cost-saving and may also reduce overall annual radiation dose. Having fewer recalls reduces stress for both the scheduler and recipient alike.
More than half of women between the ages of 40 and 49 who are diagnosed with breast cancer on screening mammography report no family history of the disease, according to a study presented at ARRS. Researchers who are critical of starting breast screening at age 40 have suggested that mammography in younger women is appropriate only for those who are at high risk for cancer, such as women with a family history of the disease. This position received backing when the U.S. Preventive Services Task Force (USPSTF) in 2009 withdrew its recommendation that women ages 40 to 49 be screened, instead recommending that they consult with their physicians. “But in our review, we found that in the subset of women with no family history and a diagnosis of invasive cancer, more than 26% had cancerous lymph nodes in their axilla. This is cancer that needs to be identified, not something that’s going to go away.”
