While noting inconsistencies with the diagnostic yield of cardiac MRI in patients who survived sudden cardiac arrest, researchers cited unique advantages in characterizing ischemic cardiomyopathy (ICM) and facilitating alternate diagnoses.
Cardiac imaging dose strategies attract close evaluation
November 30th 2010A Monday morning scientific session covering cardiac CT dose and noise broke down into newsworthy matched pairs: two studies examining the implication of CT radiation on public health, two investigating the impact of radiation reduction strategies on patient dose and image quality, and a third pair considering how noise reduction from iterative reconstruction affects the quality of images of highly calcified vessels and morbidly obese patients.
X-ray reveals Italian saint died from a cardiac embolism
June 16th 2010An x-ray taken centuries after her death proves a well-known saint died from a cardiac embolism instead of tuberculosis, as was previously thought. The body of Santa Rosa, an 18- or 19-year old girl, was naturally mummified in the 13th century.
Computer-aided dx breaks through in cardiac CTA
January 25th 2010Computer-aided detection software developed especially for coronary CT angiography could boost imagers' ability to rule out clinically relevant stenosis in patients at low to moderate risk of coronary artery disease, according to researchers at the Medical University of South Carolina.
Coronary calcium scoring can be trusted to guide cardiac test selection
December 10th 2009Coronary artery calcium scanning predicts the risk of myocardial infarction and sudden death accurately enough to guide the selection of diagnostic tests for symptomatic patients, according to a multicenter prospective study.
Technology, physiology streamline cardiac CTA contrast dose
December 3rd 2009Increasing CT scanning speeds and image resolution combined with automated injection and optimized protocols tailored to specific patient features could reduce iodinated contrast media needed for coronary CT angiography by at least half, according to several papers presented at the 2009 RSNA meeting.
Cardiac scientific sessions examine outcomes, contrast media use
November 17th 2009Cardiac imaging researchers are expanding the scope of topics considered at the 2009 RSNA meeting to include iodinated contrast media administration as a safety issue and clinical outcomes studies that weigh the relative merits of cost and clinical efficacy.
