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.
Texas technologists oppose licensure removal
June 20, 2014 -- The Texas Society of Radiologic Technologists said it opposes a recent move by a commission appointed by the Texas Legislature to eliminate licensure requirements for radiologic technologists.
Saudi study finds evidence of inappropriate CT referrals
June 19, 2014 -- A new study of CT referrals in a large academic hospital in Saudi Arabia has underlined the need to increase collaboration between clinicians and radiologists in order to follow appropriateness guidelines, attain radiation dose reduction strategies, and avoid misuse of the modality.
Chest CT details characteristics of MERS virus infection
June 18, 2014 -- Researchers in Saudi Arabia have clarified defining characteristics of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, which they say manifests in a similar way to organizing pneumonia on CT, according to a new report in the American Journal of Roentgenology.
MDCT: CT perfusion opens new windows in pancreatic disease
June 12, 2014 -- SAN FRANCISCO - Pancreatic imaging with CT perfusion (CTP) offers new ways to view the pancreas, unveiling dangerous tumors that are difficult to see with conventional CT and potentially offering more patients the chance for a cure, according to a talk at the International Symposium on Multidetector-Row CT (MDCT).
MDCT: Kalender offers update on breast CT
June 12, 2014 -- Clinical trials for a high-resolution breast CT scanner will begin in Germany in early 2015, according to a talk by Willi Kalender, PhD, at the International Symposium on Multidetector-Row CT (MDCT). The hope is that the technology will outperform full-field digital mammography and breast tomosynthesis at equivalent dose levels.
MDCT: Setting up a lung cancer screening program
June 11, 2014 -- SAN FRANCISCO - If your institution doesn't have a lung cancer screening program, it's probably time to set one up, according to a presentation on Tuesday at the annual International Symposium on Multidetector-Row CT (MDCT).
MDCT: Is California's dose reporting law really working?
June 11, 2014 -- SAN FRANCISCO - Is the California law requiring imaging facilities to report radiation dose to patients really working? Yes, but perhaps not in the way the legislation's authors had intended, according to a series of talks at the International Symposium on Multidetector-Row CT (MDCT).
MDCT: Future CT scanners will deliver more image, less noise
June 10, 2014 -- SAN FRANCISCO - Today's CT scanners can deliver, at best, about two-thirds of the signal and dose they output into their images. But continued progress toward sharper images and lower dose will require future generations of CT scanners to do better -- and within a few years they will, according to an opening-day talk at the International Symposium on Multidetector-Row CT (MDCT).
Circulation: Cancer risk low for children undergoing heart scans
June 9, 2014 -- Radiation from x-ray and CT scans of the heart is low and doesn't significantly raise the risk of cancer for young children being scanned, according to a study published on June 9 in Circulation that looked at nearly 14,000 heart scans.
Revamping your radiation dose policies for the enterprise
June 9, 2014 -- Recent regulatory changes regarding radiation dose management have made it imperative for healthcare providers to revise their imaging policies and procedures. But where should you begin? Neomi Mullens and Neil Singh from Ascendian Healthcare Consulting offer their advice.
Experts outline road map for effective CT lung cancer screening
June 6, 2014 -- The radiology community was shocked on April 30 when a Medicare advisory panel issued a vote of low confidence in CT lung cancer screening. In this article, Teri Yates of Accountable Radiology Advisors describes how some advocates of screening are moving forward in the wake of this setback.
Residents lack knowledge of radiation safety
May 30, 2014 -- Medical residents have limited knowledge of radiation safety, with just over half knowing that fluoroscopy could produce radiation-induced skin burns, for example. Radiology residents were only marginally more informed, according to survey results published in Academic Radiology.
