Gated SPECT best indicator for cardiac events
By Wayne Forrest
Myocardial perfusion abnormalities obtained after stress, as well as the extent of scar tissue detected by gated SPECT, are the best predictors of cardiac events in patients with suspected or known ischemic heart disease, according to a new Italian study.

ACC study: Coronary CTA tops other tests for long-term prognosis
By Charlene Laino
ORLANDO - Coronary CT angiography (CCTA) is better than conventional risk scores and calcium scoring at predicting the long-term prognosis of patients with obstructive coronary artery disease, researchers reported at the annual meeting of the American College of Cardiology (ACC).

ACC study: Sequential CT delivers less radiation, good image quality
By Edward Susman
ORLANDO - Using a sequential scanning mode during coronary CT angiography studies cuts radiation dose in half without impairing image quality compared to standard retrospective spiral data acquisition, according to a study presented at this week's American College of Cardiology (ACC) meeting.

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.

MRI, MDCT err in estimating cardiac functional parameters
By Eric Barnes
MRI and MDCT assessments of left ventricular functional parameters were inaccurate when evaluated on a moving heart phantom with known parameters, according to a study in European Radiology. CT, particularly dual-source CT, did outperform MRI, however.

MRI detects bleeding in the heart after a heart attack
By Wayne Forrest
British researchers are using MRI to image hemorrhaging inside the heart to determine how much damage has been caused by a heart attack. Results of the study from the Medical Research Council Clinical Sciences Centre were published online in the journal Radiology.

Multislice CT can help guide surgery for infective endocarditis
By Reuters Health
NEW YORK (Reuters Health), Feb 13 - In patients with infective endocarditis, the accuracy of multislice CT for detecting valvular abnormalities is close to that of transesophageal echocardiography, and the newer technique could help in surgical planning, according to a report in the February 3 Journal of the American College of Cardiology.
