MBIR finds same nodules as ASIR, at fraction of dose
December 13, 2012 -- Second-generation iterative reconstruction software doesn't necessarily improve radiologists' ability to detect lung nodules compared to earlier versions. But the new software permits the same lesion detection power at greatly reduced CT radiation doses, according to a study presented at last month's RSNA 2012 meeting in Chicago.
Chest x-ray use remains stable as high-tech modalities soar
December 12, 2012 -- While utilization of high-tech imaging modalities soared and then slipped over the past decade, use of the humble chest x-ray has continued at a relatively stable rate, researchers found in a study presented at the RSNA 2012 conference.
Adopting EMRs improves tracking of extravasation episodes
December 10, 2012 -- Adopting electronic medical records (EMRs) can help facilities improve their reporting of extravasation incidents that occur during contrast CT studies, researchers reported at the recent RSNA 2012 annual meeting.
Imaging IT offers bright spot in gloomy imaging industry
December 7, 2012 -- Exciting developments are under way in the imaging IT sector, which is benefiting from overall momentum in health IT. The segment has promising growth potential despite an overall slowdown in the medical imaging industry, according to analysis from market research firm Frost & Sullivan.
Mary's Musings: Head in the clouds at RSNA 2012
December 6, 2012 -- Not very long ago, it seems, I went to my first RSNA meeting. I was really impressed -- and I still am! Each year at RSNA, one gets a chance to peek ahead into the future: and ours is data. Data will allow us to step out of our black box of radiology and into our roles as physicians again.
Increased CT use may boost breast cancer risk
December 5, 2012 -- Increased use of CT may boost breast cancer risk in certain women, such as younger patients and those who receive repeat exams, according to research presented at the RSNA 2012 meeting. Nuclear medicine exams may also raise the risk of breast cancer.
USPSTF guidelines sparked decrease in screening mammo rates
December 4, 2012 -- Screening mammography guidelines issued by the U.S. Preventive Services Task Force (USPSTF) in 2009 led to a decline in breast screening, which, in the future, may lead to missed cancers, according to research presented last week at the RSNA 2012 meeting.
Yearly screening breast US benefits women with dense tissue
December 4, 2012 -- Although the optimal frequency of screening breast ultrasound for women with mammographically dense breast tissue remains under debate, study data presented at last week's RSNA 2012 meeting suggest that this population would benefit from yearly scans.
C-11 methionine PET aids diagnosis of adenomas, multiple myeloma
December 3, 2012 -- The radiotracer carbon-11 (C-11) methionine (MET) with PET/CT can help clarify negative or inconclusive FDG-PET findings in multiple myeloma patients, as well as differentiate between atypical and typical pituitary adenomas, according to two Japanese studies presented at last week's RSNA 2012 conference.
Study: Hold the contrast for CT of asymptomatic hematuria
December 3, 2012 -- In young patients undergoing urograms after a finding of asymptomatic hematuria, it may not be necessary to perform contrast-enhanced CT, as a noncontrast scan may be sufficient, researchers suggested at last week's RSNA meeting.
