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

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.
