JAMA editorials seek middle ground in Medicare payment for CT lung screening
September 30, 2014 -- Two new editorials in the Journal of the American Medical Association suggest new ways to navigate the gulf between advocates and skeptics of CT lung cancer screening by placing limitations -- for now, at least -- on the screening of Medicare-aged smokers.
Use of SPECT MPI exercise stress continues to decline
September 30, 2014 -- The convenience of pharmacologic stress agents and an increase in patient mobility issues are contributing to a decades-long decline in the use of exercise stress for SPECT myocardial perfusion imaging (MPI), according to a study presented at the American Society of Nuclear Cardiology annual meeting.
PACS Paradigm Shift: Part 2 -- VNAs, viewers, and radiology PACS
September 29, 2014 -- In part 2 of his series on enterprise medical image viewing, healthcare IT expert Michael Gray discusses the effect of vendor-neutral archives (VNAs) and universal viewers on the current image management paradigm, which has resulted in what he describes as the "step-by-step dismemberment" of traditional radiology-oriented PACS.
Repetitive strain injury common among breast imagers
September 26, 2014 -- Almost 60% of breast imaging radiologists experience repetitive strain injury, and their symptoms are exacerbated by the use of PACS, longer work hours, higher imaging volumes, and pressure to submit reports quickly, according to a study in the Journal of the American College of Radiology.
MDCT study ties aortic calcification to mortality
September 26, 2014 -- Both total aortic calcium load and calcium density measured by MDCT are associated with increased mortality risk, according to a new study in the September 23 issue of the Journal of the American College of Cardiology.
Choosing Wisely boosts use of short-course breast radiation therapy
September 25, 2014 -- The use of short-course radiation therapy protocols for breast cancer more than doubled after the American Society for Radiation Oncology recommended that shorter regimens be considered as part of the Choosing Wisely campaign. Still, shorter protocols are not common in the U.S., even though they may be preferred by patients.
JAMA: PET falls short in areas with widespread lung disease
September 25, 2014 -- A new study in the September 24 issue of the Journal of the American Medical Association found that FDG-PET has sharply lower specificity for diagnosing lung cancer in geographic regions where infectious lung disease is common. The findings could affect how PET is used for following up CT lung screening studies.
New studies underline promise of digital breast tomosynthesis
September 25, 2014 -- Digital breast tomosynthesis (DBT) is superior to conventional digital mammography when detecting breast cancer in women with dense breasts, according to research presented at this month's International Congress of Radiology. DBT also has an edge for the characterization of masses.
Big data in radiology will drive personalized patient care
September 24, 2014 -- Dynamically mining big data in radiology will help radiologists make more intelligent, consistent, and logical decisions and facilitate more personalized and precise recommendations for patient care, according to Dr. Eliot Siegel of the University of Maryland.
PACS Paradigm Shift: Part 1 -- Problems with today's PACS
September 24, 2014 -- Healthcare delivery organizations are experiencing a paradigm shift from departmental views of medical images -- typically seen in radiology and cardiology -- to a single, enterprise view that encompasses all medical images. In this article, healthcare IT expert Michael Gray explores some of the challenges that these changes present.
