Coronary calcium found on CT packs extra peril for smokers October 11, 2012 -- According to an analysis of more than 44,000 subjects over five years, smokers with coronary artery calcium (CAC) had higher mortality rates than smokers without CAC. But an absence of CAC didn't help smokers much, as they still had mortality similar to nonsmokers with mild to moderate atherosclerosis, researchers wrote in JACC: Cardiovascular Imaging.
Start-up Densitas fine-tunes breast density detection software October 11, 2012 -- As the breast density notification movement gains momentum across North America, a Canadian start-up called Densitas is putting its money into technology that will automate breast density measurement. The hope is that the software will both free up radiologists' time and standardize breast density reporting.
Challenges remain for Gamma Medica after bankruptcy filing October 10, 2012 -- The clock is now ticking for molecular breast imaging (MBI) developer Gamma Medica, which has three months to find additional financing or reorganize itself after a bankruptcy court approved a temporary financing plan last week. The outcome could impact the nascent market for MBI technology.
ClearData, HP eye cloud-based VNA market October 10, 2012 -- The burgeoning market for cloud-based vendor-neutral archives (VNA) has drawn another participant with a computing giant as a partner. With the help of HP, healthcare cloud computing services provider ClearData Networks is launching a cloud-based package for vendor-neutral archiving of medical images.
Study finds EHRs improve care in ambulatory care practices October 10, 2012 -- Use of electronic health records (EHRs) by physicians with ambulatory care practices in New York's Hudson Valley improved patient care compared with those who used paper records, according to a study published online October 3 in the Journal of General Internal Medicine.
Canadian C-spine rule rules, but may not cut imaging October 9, 2012 -- The Canadian C-spine rule is more accurate for diagnosing cervical spine injuries than another common rule addressing the injury, according to a new study in the Canadian Medical Association Journal.
Novel CT analysis tool refines COPD diagnosis October 9, 2012 -- A new image analysis technique for chest CT scans could have a big effect on the diagnosis and treatment of chronic obstructive pulmonary disease (COPD), according to a new study in Nature Medicine.
New cardiac MRI technique identifies early-stage heart disease October 9, 2012 -- By using a new MRI technique to measure the wall thickness of coronary arteries, researchers from the U.S. National Institutes of Health may be able to identify coronary heart disease early in its progression, according to a study published October 9 in Radiology.
DSCT compares full- to half-dose VC by patient October 8, 2012 -- Mayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.
Hybrid linac-MRI tracks motion during radiotherapy October 8, 2012 -- Real-time tumor tracking could prove invaluable for radiotherapy of moving targets such as lung tumors. Using MRI for such tracking provides position verification without ionizing radiation. Researchers recently discussed the latest results of a prototype hybrid linac-MRI system being developed at the Cross Cancer Institute in Canada.
