Percutaneous cardiovascular procedures 'strikingly better' with radial access
By Reuters Health
NEW YORK (Reuters Health), Mar 10 - In the real-world setting of contemporary clinical cardiology practices, adverse events following percutaneous cardiovascular procedures are substantially reduced by using radial artery access compared with using femoral access, investigators report in the March issue of Heart.

Diabetes renders coronary CTA more difficult, less successful
By Eric Barnes
VIENNA - Diabetic patients have smaller vessels and larger coronary artery calcifications than nondiabetics, a combination that reduces the utility of coronary CT angiography (CTA), according to a new study from Italy.

3D CT detection of perfusion defects mirrors SPECT
By Eric Barnes
VIENNA - Three-dimensional images from normal coronary CT angiography scans are highly sensitive for detecting fixed perfusion defects compared to myocardial SPECT. A special reconstruction technique performed with customized software does the job without the need for additional radiation or contrast.

320-slice coronary CTA permits much lower contrast dose
By Eric Barnes
VIENNA - Single-beat scanning not only enables significant radiation dose reductions in coronary CT angiography (CTA), the short duration of the scan permits drastically lower contrast doses as well, at least in patients with regular heartbeats and no arrhythmias.

320-detector-row CT cuts dose in triple rule-out exams
By Eric Barnes
Image quality is high and radiation dose is low when the so-called triple rule-out protocol is used with 320-detector-row CT to scan patients with chest pain, according to researchers from Berlin.
