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 cardiac stress test effective at predicting fatal heart disease

Stress cardiac MRI (CMR) isn’t common in clinical practices, but Duke Health researchers found the modality may hold promise as an alternative to more commonly used cardiovascular techniques for predicting fatal heart disease, according to a Feb. 8 study published in JAMA: Cardiology.

Visual assessment of stroke scans can have negative impact on patient care

Visually assessing diffusion-weighted imaging (DWI) infarct volumes proved to be inaccurate and, when using DAWN criteria, would have led to wrong decisions on thrombectomy in 19 percent of cases, according to a recent study in the Journal of NeuroInterventional Surgery.

Cardiac MRI, SPECT imaging may improve ventricular tachycardia ablation

Researchers found that combining iodine-123 metaiodobenzylguanidine (123I-MIBG) SPECT imaging with cardiac MRI helped identify specific subsets of heart tissue more prone to arrhythmia, or an irregular heartbeat, according to research published in the January issue of The Journal of Nuclear Medicine.
