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.

MRI reveals cerebellum acts as brain monitor to help improve cognitive, emotional function

Using MRI technology, researchers from Washington University in St. Louis have found the cerebellum—a part of the brain long ignored by scientists—is more involved in higher-order thinking than previously thought, according to a report published Oct. 25 by NPR.

MRI-based small vessel disease score linked to future stroke, dementia

A simple score containing four MRI markers of cerebral small vessel disease (CSVD) is associated with stroke, dementia and mortality among older adults, according to an analysis of the population-based Rotterdam Study published Oct. 24 in Stroke.

Augmented reality helps cardiologists visualize 3D images, plan complex procedures

Augmented reality (AR) allows cardiologists to visualize and explore three-dimensional (3D) myocardial scarring images in the heart as they perform ventricular tachycardia ablation or other electrophysiological surgical interventions, according to research published in PLOS One.

Can cardiac MRI replace echocardiography for diagnosing pulmonary hypertension?

Cardiac MRI can accurately diagnose patients with pulmonary hypertension (PH), according to an Oct. 23 study published in Radiology. Results may help improve PH detection rates and enhance care for patients with severe cases.
