Coronary artery calcium independently predicts risk in CAD patients
By Reuters Health
NEW YORK (Reuters Health), Jul 29 - Coronary calcium scoring can be used to predict future severe cardiac events in patients with stable coronary artery disease (CAD), according to a new study in Radiology.

Adding PET to 64-slice CT aids detection of heart disease
By Wayne Forrest
Adding functional data from PET to 64-slice coronary CT angiography can improve the latter's ability to detect coronary artery disease, overcoming the modality's historic weak point in specificity, according to U.K. researchers.

Prospectively gated coronary CTA nearly equals normal-dose scans
By Eric Barnes
Researchers in Italy report that low-dose prospectively gated coronary CT angiography (CTA) scans are nearly equivalent to retrospectively gated exams in diagnostic accuracy, while reducing radiation dose by up to 72%, according to an article published in the Journal of the American College of Cardiology.

Nuclear myocardial perfusion imaging can reduce hospital costs for suspected MI
By Reuters Health
NEW YORK (Reuters Health), Jul 13 - For low-risk emergency department patients with suspected acute coronary syndrome, acute nuclear myocardial perfusion imaging (MPI) has the potential to safely reduce the number of hospital admissions and to lower overall costs, Swedish investigators report.

MRA recommended over CTA for following Kawasaki disease
By Wayne Forrest
Italian researchers recommend coronary MR angiography (MRA) as the modality of choice in the follow-up of patients with Kawasaki disease to reduce the potential cumulative effect of radiation exposure from repeat CT angiography (CTA) exams.

Images may look different on sitting gamma cameras
By AuntMinnieEurope.com staff writers
TORONTO - Cardiac images produced on gamma cameras in which patients are imaged in the sitting position may look different than those from standard supine-oriented gamma cameras, a phenomenon that clinicians should be aware of, according to a presentation at this week's SNM meeting.

Hybrid coronary CTA, SPECT offer less radiation, shorter scan time
By Wayne Forrest
TORONTO - Swiss researchers have developed a hybrid cardiac imaging method that combines coronary CT angiography (CTA) with SPECT myocardial perfusion imaging to predict relevant coronary lesions with considerably less radiation dose and scanning time.

MR stress alone sufficient for myocardial perfusion
By Eric Barnes
Use of an automated postprocessing tool eliminates the need for both a stress and rest exam in myocardial perfusion MRI, according to researchers from Germany. They found that quantitative assessment of stress MRI images alone delivers the same diagnostic performance as semiquantitative evaluation of both stress and rest perfusion exams.

Stenosis severity tied to acute coronary syndrome risk
By Reuters Health
NEW YORK (Reuters Health), Jun 3 - Although myocardial infarction has been generally thought to be associated with coronary stenoses with a diameter reduction of less than 50%, this may not be the case, Belgian researchers report in the May issue of the American Journal of Cardiology.
