MRI technique shows how energy drinks alter heart function
December 4, 2013 -- CHICAGO - Using a novel cardiac MRI technique, German researchers found significantly increased heart contraction rates in the left ventricle of healthy young adults one hour after they consumed energy drinks, in a study presented on Monday at the RSNA annual meeting.
CORE320: CTA-CTP matches SPECT for gauging cardiac disease
November 27, 2013 -- The accuracy of 320-detector-row coronary CT angiography (CTA) combined with CT perfusion (CTP) is equivalent to that of SPECT myocardial perfusion for diagnosing functionally significant coronary artery disease, according to results of the prospective, multicenter, international CORE320 trial published in the European Heart Journal.
Italian registry shows diverse uses of MRI in cardiac disease
November 12, 2013 -- The first thorough accounting of cardiac MR use in Italy found that systems are used in a wide variety of examinations -- most relating to inflammatory disease and cardiomyopathies -- and most yield results that have a strong impact on patient management.
EU study charts path to cost-effective cardiac imaging
November 12, 2013 -- BRUSSELS - Imaging has brought unprecedented insight into cardiovascular disease, but health authorities need smarter and more cost-effective screening strategies to identify high-risk patients, according to a research project presented on Thursday at a special European Parliament hearing in Brussels.
Italian CT survey can serve as a model for Europe
November 6, 2013 -- Italy's first nationwide audit of multidetector CT (MDCT) practice, which assessed dose exposures of 5,668 patients, can act as a reference for European optimization programs and as a starting point for updating diagnostic reference levels, according to the authors.
Stress cardiac MR matches 320-row CCTA results
November 5, 2013 -- Vasodilator stress cardiac MR and 320-detector-row coronary CT angiography (CCTA) both accurately detect obstructive coronary artery disease, and the two tests are also highly concordant, according to the results of a new study in the International Journal of Cardiovascular Imaging.
Dual-energy CT can assess iodine concentration measurements
November 4, 2013 -- Dual-source CT scanners provide accurate measurements of iodine concentration across a wide range of cardiac CT protocols with the use of dual-energy CT myocardial perfusion imaging protocols, a Dutch-led research team wrote in European Radiology.
Pacemakers and MRI: Always read manufacturers' small print
October 29, 2013 -- The European Society of Cardiology has published new guidelines about MRI for pacemaker patients, but caution is still needed because the advice is incomplete, according to Dr. Jörg Barkhausen, chair of the Cardiac & Vascular Diagnostics Working Group of the German Radiology Society.
High pitch plus iterative reconstruction clips CCTA dose
October 23, 2013 -- In one of the first studies to combine a high-pitch cardiac CT angiography (CCTA) imaging protocol with iterative reconstruction, researchers from Beijing have reduced radiation doses to less than 1 mSv, with good image quality even in heavier patients.
New Dutch data look set to enliven ESMRMB congress
October 2, 2013 -- The results of a Dutch population study, to be discussed at this week's European Society for MR in Medicine and Biology (ESMRMB) meeting in Toulouse, France, show that intraplaque hemorrhage is a stronger indicator of a cardiovascular event than plaque fat content.
Germans applaud dual-source CT for low heart rate cases
September 24, 2013 -- For patients with a low heart rate who cannot hold their breath adequately during coronary CT angiography, images can be acquired during free breathing without substantial loss of image quality when using a high-pitch scan mode in certain dual-source CT machines, researchers from Munich have found.
Robert Steiner embodied radiology's links with cardiology
September 17, 2013 -- There has always been a close relationship between radiology and cardiology, and nothing shows this more than the life and work of Dr. Robert E. Steiner, who died peacefully on 12 September 2013, writes history columnist Dr. Adrian Thomas.
Whole-body MRI may predict heart attack, stroke in diabetics
September 11, 2013 -- Whole-body MRI can detect vascular changes in patients with diabetes that can signal an increased risk of heart attack and stroke, according to a new study by German researchers published online on 10 September in Radiology.
ESC: Imaging prior to noncardiac surgery may not be needed
September 4, 2013 -- AMSTERDAM - The value of medical imaging prior to noncardiac surgery for preoperative cardiac risk assessment may have been overstated. Importantly, guidelines issued in 2009 are considered insecure and may need to be rewritten, according to an expert at this week's European Society of Cardiology (ESC) meeting.
ESC: CCTA effective as initial emergency test for chest pain
September 4, 2013 -- AMSTERDAM - Use of coronary CT angiography (CCTA) does not increase the rate of subsequent invasive coronary angiography and does increase coronary revascularization in patients presenting to the emergency department with chest pain -- while also saving money, according to a poster at the European Society of Cardiology (ESC) congress.
