Atherosclerosis markers can unravel paradox of Churchill et al
By Frances Rylands-Monk
VIENNA - Winston Churchill smoked heavily and was overweight, yet he lived to the age of 90. Others live healthily and die well before 60. Emerging techniques for diagnosing atherosclerosis promise to explain this apparent contradiction and make medicine more patient-specific.

CAD aids in stenosis detection on coronary CTA
By Erik L. Ridley
VIENNA - Computer-aided detection (CAD) software can accurately rule out stenosis on coronary CT angiography (CCTA) in patients with acute chest pain and an intermediate risk of acute coronary syndrome, according to research presented at the European Congress of Radiology.

Heavy calcium won't harm CCTA accuracy in advanced scanners
By Eric Barnes
VIENNA - There's no reason to limit the use of coronary CT angiography (CCTA) in patients with high calcium scores -- as long as the scanner is 64-detector-rows or higher, according to a new meta-analysis of 27 studies presented on Friday at the European Congress of Radiology.

Researchers grapple with aortic measurements in cardiac MRI
By Philip Ward
VIENNA - Cardiovascular MRI is becoming increasingly appealing in population-based research, but accurate measurement of the diameters of the aorta and pulmonary trunk remains a key difficulty that needs to be addressed, according to participants at yesterday morning's well-attended vascular refresher course.

Low-voltage technique slashes radiation dose in CCTA
By Erik L. Ridley
VIENNA - The combination of 100-kV CT tube voltage and a low-noise reconstruction filter can significantly lower radiation dose in coronary CT angiography (CCTA) while maintaining image quality, according to a study presented at the European Congress of Radiology.

High-field MRI creates new options in cardiac cases
By Philip Ward
VIENNA - Successful cardiac examinations with 3-tesla MRI do not require wizardry or exceptional powers, but they do call for solid knowledge of the potential problems and the technical aspects of the equipment, according to a presentation on Thursay at the European Congress of Radiology.

Whole-body CTA outpredicts Framingham for cardiac events
By Eric Barnes
An individual's total plaque burden at whole-body CT angiography (CTA) is a far more accurate predictor of cardiovascular risk than traditional risk-assessment measures, Italian researchers have discovered.

Study: Don't overlook radioisotope imaging in cardiac cases
By Philip Ward
Technetium-99m sestamibi myocardial perfusion scanning is still an excellent tool in assessing myocardial function when compared with more modern cardiac imaging modalities and should not be ignored, U.K. researchers from the Royal London Hospital have found.

Europe revises cardio guidelines to urge better adoption
By AuntMinnieEurope.com staff writers
The next edition of the Joint European CVD Prevention Guidelines, scheduled to be published in May, will be simplified so that guidelines for preventing cardiovascular disease will be easier to understand and put into daily practice.

Heart failure, ischemia, tied to gray-matter loss at MRI
By Eric Barnes
Heart failure is associated with gray-matter loss at MRI and a worsening of both memory and psychomotor skills. To a lesser extent, the presence of ischemic heart disease slows recall as well, according to a new study in the European Heart Journal.

Stress dynamic myocardial perfusion CT a 'viable alternative'
By Eric Barnes
Dual-source CT can compete with MRI and SPECT in the performance of sophisticated cardiac scans that combine anatomic and functional imaging for a comprehensive assessment of patients with suspected coronary artery disease, say researchers from Spain and the U.S.
