CCTA sensitive for high-risk coronary disease, overcalls stenosis
By Eric Barnes
Coronary CT angiography (CCTA) is highly accurate for diagnosing the most dangerous forms of coronary artery disease -- left main artery disease or three-vessel disease -- but the examination significantly overcalls the extent of atherosclerosis compared with angiography, Dutch researchers reported at RSNA 2012.

Low-dose CT raises coronary calcium scores; IR corrects them
By Eric Barnes
Low-dose coronary artery calcium (CAC) scores are reliable if iterative reconstruction (IR) is applied to the CT data, according to research presented at RSNA 2012. Dutch researchers found that the technology ensures the accuracy of CAC scores that would otherwise be higher and less predictable than the results of higher-dose CT scans.

Automated tube current selection keeps CCTA quality, cuts dose
By Eric Barnes
Using software that automatically selects the tube current modulation significantly reduces the radiation dose in coronary CT angiography (CCTA) compared with manual kV selection based on patient size, researchers from South Korea reported at RSNA 2012.

Study: CCTA technique skips the breath-hold
By Eric Barnes
Patients undergoing coronary CT angiography (CCTA) no longer have to hold their breath when doing so is challenging for them. CCTA images acquired on a 320-detector-row scanner using a free-breathing technique are similar to the traditional breath-hold images.

New algorithm can boost CTA resolution in obese patients
By Eric Barnes
A new reconstruction algorithm increases the accuracy and diagnostic performance of dual-source CT angiography (CTA) by raising the temporal resolution of images acquired at slow gantry rotation speeds, making it suitable for obese patients, a German-U.S. research project has found.

Dutch group works on producing clearer ultrasound images
By Tami Freeman, PhD
Lipid-coated gas microbubbles injected into the blood can be used as an ultrasound contrast agent for diagnosis of cancers or cardiovascular disease. However, most existing contrast-enhanced ultrasound techniques suffer from artifacts due to nonlinear wave propagation through the contrast agent.

New rules pave way for faster MR training for German cardiologists
By Frances Rylands-Monk
The prospect of more intense turf battles between cardiologists and radiologists in Germany is looming large following a change in the requirements for MRI certification at the local level. The new certificate takes only 12 months of training in a cardiology department and involves the reading of 300 MR images.
