Ambient light rapidly degrades image quality on mobile devices
October 18, 2013 -- Maybe there's a reason radiologists work in dark rooms. A new study has found that the ability to interpret images correctly with mobile displays begins to decline if the devices are used in ambient light conditions brighter than the average office.
How will Obamacare affect academic radiology?
October 17, 2013 -- With the government shutdown behind us, implementation of the U.S. Patient Protection and Affordable Care Act (aka Obamacare) continues to proceed. Its effects will extend into academic radiology, which can adapt by focusing on value, not volume, according to a review published in the October Academic Radiology.
PET shows link between arterial stiffness and dementia
October 17, 2013 -- PET scans show that elderly people with hardening of the arteries are more likely to have beta-amyloid plaque in the brain, even if they show no signs of dementia or Alzheimer's disease, according to a study published online October 16 in Neurology.
Google documents declining interest in radiology residency
October 16, 2013 -- Discouraged, perhaps, by falling reimbursement and the dearth of jobs in radiology, the number of individuals performing Google searches for "radiology residency" has dropped substantially in the past several years, aligning with actual residency match data, according to researchers from Philadelphia.
New breast MRI exam ready to screen women with dense breasts
October 16, 2013 -- Conventional x-ray mammography is a notoriously poor tool for screening women with dense breast tissue. Breast MRI is a possible alternative, but the cost of the exams is prohibitively high. A Michigan breast specialist believes he has changed the equation with a streamlined breast MRI screening exam that could be ready for widespread clinical use.
Sports injury website brings radiology's insights to the fans
October 15, 2013 -- Ardent sports fans can easily explain a blitz, play-action fake, suicide squeeze, and icing. What many of them can't do is describe a torn anterior cruciate ligament or plantar fasciitis. The founder of a new website, InsideInjuries.com, hopes to change that -- and in the process help educate the public about radiology.
MRA helps detect risk from unruptured cerebral aneurysms
October 15, 2013 -- MR angiography (MRA) using a 3D time-of-flight sequence could well be the most efficient technique for detecting unruptured cerebral aneurysms and determining if they pose a health risk, according to a study published in the October 15 issue of Annals of Internal Medicine.
Nonrads now performing bulk of US-guided procedures
October 14, 2013 -- Radiologists no longer predominate in the performance of ultrasound-guided procedures, which may have implications for the quality of patient care, according to a study published online in the Journal of the American College of Radiology.
MBIR halves CT dose in children, outperforming ASIR
October 14, 2013 -- In one of the first studies to evaluate advanced CT iterative reconstruction techniques in children, researchers found that model-based iterative reconstruction (MBIR) can halve pediatric CT radiation dose, delivering images of equal or better quality than standard-dose exams and outperforming first-generation IR software, according to a new article in Radiology.
Better training key to unlocking molecular imaging's potential
October 11, 2013 -- Molecular imaging has vast potential to improve healthcare in the coming years by allowing more directed, personalized therapy. But molecular imaging's contribution may be limited until more imaging specialists are trained to interpret scans acquired with the new types of tracers being developed.
Panel recommends new US criteria for judging viable pregnancy
October 10, 2013 -- To lower the risk of incorrectly diagnosing a pregnancy as nonviable, more-stringent criteria for ultrasound scans should be used to determine if a first-trimester pregnancy cannot result in a live-born baby, advised a multispecialty panel in an article published October 10 in the New England Journal of Medicine.
Straight Talk From the PACSman: Lessons learned
October 10, 2013 -- Long-time AuntMinnie.com columnist Michael J. Cannavo is back as a PACS consultant after a two-year stint with a major PACS vendor. He shares his observations and PACS wisdom in a new series called Straight Talk From the PACSman.
JACR: Residents teach as effectively as faculty
October 10, 2013 -- Residents are as effective as radiologists in teaching medical students about radiology, according to a new study in the Journal of the American College of Radiology. The findings suggest that medical schools might want to consider including more residents as teachers.
