Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Absence of calcification predicts CTA misdiagnosis

The absence of coronary calcification may dupe readers into dismissing signs of obstructive coronary artery disease (CAD) on CT angiography (CTA) scans. That is one of several predictors of diagnostic inaccuracies identified in a study published in the Journal of the American College of Cardiology Cardiovascular Imaging’s September issue.

Cardiac Pipeline: What Radiopharmaceuticals Offer

Multiple radiopharmaceuticals in the development pipeline are showing promise in cardiology. One expert shared some of the radiopharmaceuticals that inspire the most enthusiasm.

Q&A: Giving Image-guided Stroke Trials a Boost

As co-chair of the Stroke Imaging Research group, Max Wintermark, MD, is spearheading an initiative to build a database of imaging facilities’ capabilities to facilitate image-guided stroke clinical trials. Wintermark, chief of neuroradiology at the University of Virginia Medical School in Charlottesville, recently discussed with Cardiovascular Business.

Dr. Michael Pfeiffer, a cardiologist and assistant professor of medicine at Penn State Hershey Heart and Vascular Institute in Hershey, Pa. discusses the advantages of 3D volume echocardiography in the right heart.

3D LAVImin better predictor of cardiac outcomes?

Both minimal left atrial volume index (LAVImin) by 2-dimensional and 3-dimensional echocardiography (2DE and 3DE) can predict future cardiac outcomes, but 3D LAVImin seemed to be a stronger and more additive predictor than 3D maximal left atrial volume index (LAVImax). These findings were published online Sept. 4 in JACC: Cardiovascular Imaging.

FD-OCT more accurate than IVUS and angiography

Using frequency domain optical coherence tomography (FD-OCT) to obtain coronary measurements yields images that are more accurate than measurements obtained by intravascular ultrasound (IVUS) and quantitative coronary angiography, according to a study published online Sept. 4 in JACC: Cardiovascular Imaging. The modality was also more sensitive than IVUS in making certain stent measurements.

Simple teaching may improve accuracy of LVEF estimation

Self-guided teaching designed to strengthen the ability to more precisely estimate left ventricular ejection fraction (LVEF) led to decreased interobserver variability and more accurate EF measurements among a group of sonographers and cardiologists. These findings were published online Aug. 30 in the Journal of the American Society of Echocardiography.

Inauguration at the Montreal Heart Institute: A leading-edge magnetic resonance centre

On Thursday evening, the Montreal Heart Institute (MHI) inaugurated its brand new Philippa and Marvin Carsley Cardiovascular Magnetic Resonance Centre, in honour of the loyal donors. Their generous contribution will allow the MHI to operate this equipment, positioning our hospital as one of the leading cardiology centres specialized in cardiovascular imaging.
