Heart societies issue new guidelines on cardiac cath
May 10, 2012 -- A report issued on Wednesday by the American College of Cardiology Foundation and several other medical societies offers detailed criteria for determining when invasive cardiac catheterization is a reasonable option for evaluating patients for heart disease.
PET tops SPECT, cardiac MR in diagnosing artery disease
May 2, 2012 -- SPECT, cardiac MR, and PET all reached high sensitivity for detecting obstructive coronary artery disease, but PET turned in the best diagnostic performance in a meta-analysis published in the May 8 edition of the Journal of the American College of Cardiology.
Study shows less contrast still performs well in cardiac MRI
 April 27, 2012 -- Italian researchers have found that one dose of gadobutrol appears to be just as effective as a double dose of gadopentetate dimeglumine for detecting late enhancement in cardiac MRI cases, potentially reducing possible adverse effects from contrast use.
PET/CT locates infection in patients with implantable cardiac devices
 April 26, 2012 -- FDG-PET/CT can help differentiate between infection and postoperative inflammation in patients with cardiovascular implantable electronic devices and direct physicians to more appropriate treatment, according to a study published in the May issue of the Journal of the American College of Cardiology.
Cocaine use linked to mixed coronary plaque on CT
 April 24, 2012 -- Cocaine users are known to have higher-than-normal rates of acute coronary syndrome compared to others at risk of heart disease. Researchers from the Medical University of South Carolina used dual-source CT to learn more about how cocaine use affects the development of coronary atherosclerosis.
Integrating images with EHR yields dividends
April 13, 2012 -- Integrating PACS with the electronic health record (EHR) is no easy task, but it's worth the effort to provide clinicians with access to a single, comprehensive view of patient clinical information, according to a team from Harris County Hospital District in Houston.
Late gadolinium enhancement, cardiac MRI show value
April 10, 2012 -- Late gadolinium enhancement through cardiac MRI can help predict adverse cardiovascular events among hypertrophic cardiomyopathy patients, according to a study scheduled for publication in the April 17 addition of the Journal of American College of Cardiology.
MESA: Metabolic syndrome, diabetes boost CAC, cardiac events
April 9, 2012 -- People with metabolic syndrome and/or diabetes mellitus have greater progression of coronary artery calcium (CAC) than those without the conditions, and the degree of progression in CAC predicts the risk of future cardiac events, according to a study in the Journal of the American College of Cardiology.
ACC: CCTA improves chest pain evaluation without raising costs
March 29, 2012 -- CHICAGO - Performing coronary CT angiography (CCTA) early in the evaluation of chest pain in the emergency department may quickly and accurately predict which patients should be admitted for acute coronary syndrome, according to study results presented at the American College of Cardiology (ACC) meeting.
ACC: Coronary CT angio rule outs heart attack in ER patients
March 26, 2012 -- CHICAGO - Patients who have a negative coronary CT angiogram after presenting at the emergency room (ER) for cardiac-suspected chest pain can safely be sent home, researchers reported at this week's American College of Cardiology (ACC) meeting.
Moments in Radiology History: Part 2 -- Cardiovascular x-ray
 March 26, 2012 -- In early 1896, just after the birth of medical x-ray, doctors experimenting with the new rays realized that in addition to imaging bones, the technology was useful for the circulatory system. In part 2 of our series on radiology history, Otha Linton explores the roots of interventional radiology, from Forssmann to Dotter.
Medical societies release guidelines on cardiac radiation
March 22, 2012 -- A coalition of medical societies released new guidelines on dose optimization of cardiac imaging scans on Thursday in the Journal of the American College of Cardiology. The document offers a roadmap for improving radiation safety and reducing patient radiation dose while obtaining high-quality medical images.
CVIS, RIS offer growth prospects amidst PACS saturation
 March 14, 2012 -- While the PACS markets in most developed regions have reached a point of high saturation, the worldwide market for cardiovascular information systems (CVIS) and radiology information systems (RIS) is expected to be worth $600 million in 2012.
