CT lung screening participants not bothered by false positives
July 25, 2014 -- Participants in the massive National Lung Screening Trial weren't troubled by false-positive initial results suggesting they might have cancer -- possibly because they had been well-prepared in advance for such alarms, according to a report published today in Cancer.

Ohio hospital slashes CT radiation dose -- and cancer risk
July 16, 2014 -- By changing its scanning protocols, an Ohio hospital was able to cut by more than half the number of radiation-induced cancers that would have occurred following CT exams. The finding could alter the debate over the risks of medical radiation, according to a study in the July issue of the Journal of the American College of Radiology.
Boston hospital adjusts operations after marathon bombing
July 15, 2014 -- In a paper published online July 15 in Radiology, staff from Brigham and Women's Hospital details the hospital's response to the Boston Marathon bombing and how it has improved some operations and procedures to better handle emergency situations.
Get to know referring physicians to meet their imaging needs
July 14, 2014 -- If you're a radiologist, you know that referring clinicians are your customers, and it's important to keep them happy. What do your referring physicians really want from their radiology reports and interactions with the radiology department? Just ask them, according to researchers from Duke University.
Reducing CT malpractice risk: Simple, but not easy?
July 11, 2014 -- Malpractice risk is part of practicing medicine, and although radiologists are less likely than most physicians to be hit with malpractice claims, radiologists still have a 50% likelihood of being sued by the time they turn 60.
Automated algorithms help spot change in serial CT exams
July 7, 2014 -- Most PACS vendors don't include automatic deformable image registration algorithms in their workstation software. But they should, as these can sharply reduce the time it takes for radiologists to match lung nodule locations on serial lung CT scans, according to researchers from Stony Brook Medicine.
Nodule size matters in Italian CT lung cancer screening study
June 26, 2014 -- Italian researchers believe they have struck a good balance in CT lung cancer screening by following up suspicious nodules at a slightly larger size threshold than that used in previous studies. By only following up nodules 5 mm and larger rather than 4 mm, they achieved good sensitivity with fewer false positives, according to a new study in the Journal of Thoracic Oncology.
Lung cancer screening of seniors: Should CMS regulate?
June 24, 2014 -- A just-published proposal in the Annals of Internal Medicine seeks to balance the benefits and harms of CT lung cancer screening by limiting the screening of Medicare beneficiaries to lung cancer screening centers that would be accredited based on still-evolving society-based guidelines.
New knowledge changes use of CT in guiding stroke treatment
June 23, 2014 -- Intravenous tissue plasminogen activator works better and is harmful to fewer patients than most doctors think, and, in any case, stroke treatment shouldn't be denied just because CT perfusion says the ischemic area is too large, according to a presentation earlier this month at the International Symposium on Multidetector-Row CT.
ISCT's Rubin issues challenge to image processing firms
June 20, 2014 -- Advances in image processing have given radiologists new tools to find the abnormalities they're looking for. But Dr. Geoffrey Rubin believes that radiologists need better tools -- and quickly -- before they drown in a flood of data being produced by the new generation of CT scanners.
