Dual-source CTA turns in mixed results for coronary stenoses
By Wayne Forrest
Dual-source CT angiography (CTA) achieves a high negative predictive value in excluding coronary artery stenoses in patients with stable coronary artery disease, but the modality is "very limited" in its ability to predict the presence of ischemia, according to a study by German researchers.

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.

High-pitch cardiothoracic CTA skips breath-holds and high doses
By Eric Barnes
A new way to use CT angiography (CTA) to scan fast-moving targets -- such as fidgety children and grown-ups with rapid heartbeats -- is becoming routine at a hospital in France.

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.

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.

MRA planning halves radiation, contrast dose during UAE
By Kate Madden Yee
German researchers have found that performing an MR angiography (MRA) scan for planning prior to uterine artery embolization (UAE) can cut both radiation and contrast dose in half, according to a study published in the June issue of Radiology.

Biological dose measures promise new view of cardiac imaging risk
By Eric Barnes
The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.
