Laxative-free CT colonography (CTC) provided reasonable accuracy in the detection of adenomas 10 mm or larger and improved patient comfort compared with optical colonoscopy, according to a study published May 15 in
Annals of Internal Medicine.
LAS VEGAS—When treating a real-world sample of patients for intermittent claudication or critical limb ischemia, two off-label iliac artery stents showed a statistically significant performance goal for low major adverse event rates, according to the late breaking MOBILITY trial results presented May 10 at the 35th annual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI). During the press conference, experts suggested that this study may further reinforce the role of percutaneous treatments over the more invasive surgical option for these sick patients.
The inception of national incident reporting systems in other medical specialties and high-risk industries has produced demonstrable improvements in safety, and radiology could realize similar benefits if the profession implemented such a system. However, medical imaging lags behind in adoption of a national system, according the authors of an article published in the May issue of
Journal of American College of Radiology.
CT-induced cancer is always a concern when imaging younger patients, but an analysis of radiation risks has shown that young patients who undergo chest or abdominopelvic CT are more than 35 times more likely to die of their disease than develop a radiation-induced cancer, according to a study presented May 1 at the annual meeting of the American Roentgen Ray Society in Vancouver.
Using a decision support system for ordering chest CT exams results in positive examinations more than three-quarters of the time, according to a study presented May 1 at the annual meeting of the American Roentgen Ray Society in Vancouver.
MR enterography proved superior to CT enterography in the diagnosis of fibrosis in children with Crohn’s disease and comparable to CT in the detection of active inflammation, according to a study presented April 30 at the annual meeting of the American Roentgen Ray Society in Vancouver.

Iterative reconstruction of pediatric chest and abdominal CT images nearly halved radiation dose, while maintaining image quality and diagnostic confidence, according to a study published in the May issue of
Radiology.
The American College of Radiology’s (ACR) Radiology Leadership Institute (RLI) has released the official program for the RLI inaugural event, to be held July 12-15, at the Kellogg School of Management on Northwestern University’s Evanston, Ill., campus.
CHICAGO—Using cardiac CT angiography (CCTA) early on in the presentation of chest pain may more accurately assess patients who should be admitted for MI, according to the results of the late-breaking ROMICAT II trial presented March 27 at the 61st annual American College of Cardiology (ACC) scientific session. Additionally, CCTA resulted in a reduction of length of stay at essentially no increased cost.
Portable DR systems have matured from clunky, barely usable iterations to sleeker units seemingly well-suited for the challenges of portable imaging.
Medicare beneficiaries who underwent coronary CT angiography (CCTA) in nonacute settings had a higher likelihood of undergoing subsequent invasive cardiac procedures and have increased coronary artery disease spending compared with patients who underwent stress testing, according to a study published March 7 in the
Journal of the American Medical Association. In response, several researchers submitted letters supporting and challenging the author’s findings.
CT angiography (CTA) protocol developments designed to speed imaging and optimize arterial opacification may have an unintentional side effect and overestimate acute ischemic infarct size, according to a study published in the February edition of
Radiology. The discrepancies could have inappropriately excluded up to 90 percent of eligible stroke patients from reperfusion therapy if they had been used to inform treatment decision making.
Inflammation, as assessed by 18F-FDG-PET uptake and histology, is increased in plaques containing high-risk morphological (HRM) features and rises with increasing number of HRM, according to a study in the January issue of
Circulation: Cardiovascular Imaging. Study authors suggested that data support the concept that inflammation accumulates relative to the burden of morphological abnormalities.
Massachusetts General Hospital (MGH) in Boston has added Agfa HealthCare’s Impax Data Center and also intends to upgrade to Impax PACS version 6.5 as the hospital expands its relationship with the Mortsel, Belgium-based healthcare IT vendor.
The pace of progress in developing interoperability between medical devices and data destinations is influenced as much by well-articulated demand as by technical capability—and it’s up to CMIOs and other beneficiaries of such interoperability to push the issue, said Julian M. Goldman, MD, medical director of the biomedical engineering program at Partners HealthCare System in Boston.
Two studies published in the January issue of the International Journal of Radiation Oncology•Biology•Physics demonstrated the effectiveness of proton therapy in treating prostate cancer. One study revealed the therapy’s effectiveness while limiting side effects; the other showed that external beam therapy can achieve results comparable to brachytherapy.
At RSNA 2011, the latest and greatest in radiology engaged nearly 60,000 imaging and informatics stakeholders.
Mach 7 Technologies debuted the Keystone Study Split Utility, a CT and MRI segmenting software, which can be used to reduce the time required to split multiregion CT and MR scans into anatomic regions that match the original orders from the RIS and reducing the time required for the newly split studies to be sent to the PACS, at 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) in Chicago.
CHICAGO—The implementation of clinical decision support resulted in a marked, positive change in the utilization pattern for breast MRI, according to a study presented Nov. 30 at the Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
CHICAGO--Despite early assumptions that meaningful use (MU) targeted only primary care, the Centers for Medicare & Medicaid Services has paid nearly $1 billion to eligible providers and less than half of that amount has been distributed to primary care physicians, Keith J. Dreyer, DO, PhD, vice chairman of radiology at Massachusetts General Hospital in Boston, said during a Nov. 29 session at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
