Confusion over radiation risk could lead to inappropriate exams
May 29, 2013 -- When radiologists have access to radiation exposure histories for patients, most will take them into consideration when assessing the risk of further exposure in future imaging exams, according to a new study published in the June issue of the American Journal of Roentgenology. But should they?
Plaque volume on CCTA outperforms luminal narrowing for diagnosis
May 29, 2013 -- Total plaque volume at coronary CT angiography (CCTA) is a more reliable predictor of stenosis than luminal narrowing -- to the point where it could help differentiate between patients who have stenosis detected on CCTA and the smaller number with true flow-limiting lesions that need treatment, wrote researchers in the Journal of the American College of Cardiology.
Imaging groups urge CMS not to adopt FDG-PET scan limitations
May 28, 2013 -- Radiology, nuclear medicine, and neuroradiology organizations are anxiously awaiting a decision from the U.S. Centers for Medicare and Medicaid Services (CMS) that would finalize its proposal to limit FDG-PET coverage to one nationally covered scan.
Imaging experts mull over color challenges
 May 28, 2013 -- Color images are technically difficult to deal with, creating a thorny issue that's growing as PACS broadens from radiology and cardiology to include other specialties that use color-heavy images. Medical informatics expert Dr. David Clunie discusses a recent meeting designed to provide a framework for handling color.
Clear scanner protocols can help avoid CT radiation mistakes
May 27, 2013 -- CT protocols are getting more complex with each new scanner generation, challenging even the best-run radiology departments. Fortunately, a comprehensive protocol plan can minimize the fuss -- and the potential for dangerous mistakes, according to a talk at the Virtual Symposium on Radiation Safety and Computed Tomography.
Decision-support tool slashes inappropriate heart imaging
May 24, 2013 -- The use of physician decision-support software based on appropriateness criteria eliminated three-fourths of inappropriate imaging exams for evaluating coronary artery disease, according to a study published online May 21 in the Journal of the American College of Cardiology.
CAD for breast MRI improves sensitivity; accuracy not so much
 May 24, 2013 -- Computer-aided detection (CAD) technology improves sensitivity in breast MRI for both experienced and novice readers, but it does not significantly advance overall accuracy, according to a study published in the June issue of the American Journal of Roentgenology.
NLST update: CT sees twice the lung cancers of x-ray
May 23, 2013 -- A new analysis of data from the landmark 2011 National Lung Screening Trial (NLST) found that low-dose CT detected twice as many early-stage lung cancers as x-ray on initial screening, cementing CT's promise as a tool that can reduce lung cancer mortality by 20% or more, according to results published in the New England Journal of Medicine.
RBMA: To thrive, imaging groups must dare to be different
 May 23, 2013 -- Radiology practices face serious challenges in their efforts to be the preferred imaging choice in their markets, especially because the field is so crowded, according to a May 22 presentation at the Radiology Business Management Association (RBMA) meeting in Colorado Springs, CO. The key to survival? Truly distinguishing your group from other providers.
BMJ: Megastudy links pediatric CT to higher cancer rates
May 23, 2013 -- The largest study to probe the effects of ionizing radiation since the atomic bomb survivor studies shows that cancer incidence does rise among younger patients -- although only in small amounts -- in the years following their exposure to CT scans, according to an Australian article published May 21 in BMJ.
SalaryScan data reveal gender gap between U.S. radiologists
 May 22, 2013 -- Male radiologists make an average of 20% more than female radiologists in the U.S., according to new salary data from AuntMinnie.com. While the salary advantage for men is in line with the U.S. average for all professions, it could reinforce the perception that radiology is an unfriendly career choice for women.
AJR: DBT reduces screening recall rates by 37%
 May 22, 2013 -- Digital breast tomosynthesis (DBT) when used as a screening tool for breast cancer reduces recall rates by 37% and increases the detection of invasive cancers by 54%, according to a new study published online May 22 in the American Journal of Roentgenology.
Chinese MRI researchers arrested on conspiracy, bribery charges
May 21, 2013 -- Federal authorities have arrested Chinese researchers who worked on MRI technology at NYU Langone Medical Center for allegedly acquiring research money from the U.S. government and then sharing technological information with a Chinese company and government-sponsored research institute in China.

Workflow optimization in radiology
Bochum, 19 June 2013 – Has PACS reached the end of its technological development? Or can image management be further enhanced despite the extremely high level of functionality that has already been achieved? The answer is “clearly yes”!
The needs and requirements both in radiology and in the hospital at large are constantly changing and PACS should not only accompany this change but be one of its major drivers.Press ReleaseLink
