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.

MR predicts cardiomyopathy recovery

Findings from cardiac MR (CMR) and a novel biomarker better predict left ventricular reverse remodeling in patients with recent-onset dilated cardiomyopathy than do endomyocardial biopsy results, according to a study published Jan. 8 in the Journal of the American College of Cardiology: Heart Failure. While the study had many limitations, it underscores the value of CMR, the accompanying editorial suggested.

MRI software helps to detect damage from stroke

By adapting a technique in oncology, physicians used standard MRI scans to more accurately measure damage to the blood brain barrier in stroke patients. If further validated, the results may offer a method to identify which patients might benefit or be harmed if treated with tissue plasminogen activator (tPA). The study was published online Dec. 20 in PLOS ONE.

PET MPI stratifies risk, but clinical relevance uncertain

A large, multicenter observational study has found that PET myocardial perfusion imaging (MPI) is a powerful predictor of incremental risk of cardiac death in patients with known or suspected coronary artery disease.

ASE, GE partner in India for cardiovascular ultrasound training

The American Society of Echocardiography (ASE) and GE Healthcare have teamed to provide a cardiovascular ultrasound training event for healthcare providers caring for underserved populations in rural northwest India.

Ex-cath lab tech indicted in Hep-C outbreak

A former cath lab medical technician dubbed the “serial infector” has been indicted by a federal grand jury in connection with a hepatitis C outbreak in New Hampshire and several other states.

CCTA bests angio for undetected lesions

Coronary CT angiography (CCTA) identified plaques in acute MI patients whose coronary angiograms did not produce evidence of significant coronary stenosis.

Bracco issues Class I recall of Isovue injector syringes

Bracco Diagnostics is voluntarily initiating a Class I recall of nine lots of iopamidol injection (Isovue) prefilled power injector syringes (PFS), which are used in combination with Stellant CT injection systems, due to the presence of visible particles in syringes observed at the end of standard stability studies on retained samples.

ECG results in AF patients predict adverse outcomes

Results from routine electrocardiograms (ECGs) in patients with atrial fibrillation (AF) can accurately predict later adverse events, researchers reported Oct. 28 at the Canadian Cardiovascular Congress in Toronto.
