Treatment guidelines for chronic heart failure receive overhaul
August 16, 2011 -- The U.K. National Institute for Health and Clinical Excellence (NICE) has published clinical guidelines for the diagnosis, treatment, and monitoring of chronic heart failure in adults in the August 16 issue of the Annals of Internal Medicine. These new guidelines update and make important changes compared with prior recommendations issued by NICE in 2003.
Flat-detector CT helps diagnose congenital heart disease
August 8, 2011 -- They require a little more contrast and dose, but catheterization procedures performed with flat-detector CT offer high-resolution images that can improve the diagnosis of congenital heart disease in children, according to a new study in European Radiology.
High-pitch stent assessment drives down dose
August 3, 2011 -- Physicians in Singapore are evaluating stent patency using extremely low radiation doses with the aid of dual-source MDCT, according to a presentation at the recent Society of Cardiovascular Computed Tomography meeting in Denver.
Stem cell regeneration of heart tissue methods await refining
July 27, 2011 -- An original paper in European Radiology scans the many promising developments in stem cell regeneration of cardiac tissue following myocardial infarction. Researchers from the Netherlands find there is no "best method" in cell tracking but rather an array of techniques.
Germans support imaging arrhythmia patients with single-beat CT
July 26, 2011 -- Single-beat cardiac CT not only allows for dose reduction and high accuracy, but also for greater flexibility in imaging patients with arrhythmia, atrial fibrillation, and shortness of breath, said a researcher from Charité Medical University in Berlin.
Cardiovascular MRI sheds light on cardiomyopathy
July 19, 2011 -- Cardiovascular MRI has revealed that stress cardiomyopathy may have broader clinical characteristics than previously reported, including younger patients, men, and patients without an identifiable stressful cause, according to a study in the July 20 issue of the Journal of the American Medical Association.
iSi 2011: MRI advances in analysis of cardiac function
July 18, 2011 -- A leading European MR expert has stressed that late gadolinium enhancement imaging of the nonischemic heart continues to show promise in differential diagnosis, both as a prognostic outcome predictor when disease is already established and as a guide to therapeutic decisions.
What MRI can (and can't yet) do for cardiac imaging
July 12, 2011 -- MRI opens a window into heart disease that is more specialized and more powerful than other imaging methods. Still, many of MRI's best diagnostic tools remain clumsy and time-consuming, its images burdened by artifacts, and its results unproven, said a presenter at an MRI symposium in Berlin.
Perfusion CT can help assess coronary artery disease
July 12, 2011 -- CT angiography has carved out a niche in heart imaging thanks to its ability to display cardiac morphology. But German researchers think it could have a role to play in functional imaging as well with the use of a dynamic CT perfusion technique they've developed that measures myocardial blood flow.
Cardiac specialist gives tips on optimizing CT image quality
June 30, 2011 -- Patient selection, preparation, and assessment are the vital considerations to ensure image optimization in cardiac CT, according Dr. James Stirrup of London's Royal Brompton Hospital. He offered tips on optimizing CT image quality at the recent British Institute of Radiology President's Conference.
CT predicts cardiovascular events in symptomatic patients
June 23, 2011 -- CT is a strong predictor of cardiovascular events in symptomatic subjects, according to a meta-analysis conducted by German researchers and presented at the recent International Society for Computed Tomography meeting in San Francisco.
