Cardiovascular Imaging

CT angiography (CTA) and transcranial Doppler (TCD) fall short in detecting cerebral vasospasm (CVS) and predicting delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH), reported authors of a recent study published in the inaugural edition of Critical Care Explorations.

Researchers used T2 mapping taken from weekly cardiac MRIs to help identify cardiotoxicity at an early stage, according to results of a pig study published Feb. 18 in the Journal of the American College of Cardiology. The findings could help cancer patients at risk of chemo-induced heart failure.

Autosomal dominant polycystic kidney disease (ADPKD) is among the most common hereditary diseases and is associated with complications such as intracranial aneurysm. A lack of screening guidelines prompted a group of researchers to evaluate the cost-effectiveness of various MR angiography strategies.

Stress cardiac MRI (CMR) greatly improved the accuracy of mortality prediction in patients with known or suspected coronary artery disease (CAD), reported authors of a large, multi-center study published in JAMA Cardiology.

A new cardiovascular imaging technique can reveal important information about the plaque characteristics of a patient’s carotid artery in real time, reported authors of a recent study published in Radiology. One researcher believes the method has the potential to become as popular as ultrasound.

The American Heart Association (AHA) and American College of Cardiology (ACC) have endorsed CT coronary artery calcium (CAC) testing as a decision aid to determine a patient’s risk of heart disease.

 

A team of researchers from the University of Texas (UT) at Austin developed a noninvasive 3D imaging technique that can provide surgeons customized models of the hearts of mitral valve (MV) disease patients for presurgical planning, according to research published in the January issue of Annals of Biomedical Engineering. 

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.

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.

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.  

Hospitalized women with ischemic stroke are less likely than men to be evaluated by stroke specialists and receive specialized imaging scans and other diagnostic testing in hospitals, according to research being presented at this year's American Stroke Association International Stroke Conference in Honolulu.

A combined deep learning method better detected hemorrhages and identified different subtypes of intracranial hemorrhage than single algorithms used alone, according to a new study published in the Journal of Digital Imaging.
