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.

Brain MRIs of young adults with above normal blood pressure revealed a higher risk of brain shrinkage than young adults with normal blood pressure, according to a study published online Jan. 23 in the journal Neurology

Non-gated chest CT with 256-detector row is more reliable for detecting and measuring coronary artery calcification (CAC) compared to dedicated calcium scoring CT (CSCT), reported authors of a Jan. 23 study published in Academic Radiology.

The American Society of Echocardiography has released new guidelines for performing a comprehensive transthoracic echocardiography (TTE) examination. The recommendations, which were endorsed by 22 other cardiology/echocardiography societies from around the world, were published in the January edition of the Journal of the American Society of Echocardiography.

The FDA recently gave 501(k) clearance to medical imaging device iCertainty which noninvasively shows blood flow without the need of injection, dyes or radiation.

The RAPID neuroimaging platform has been cleared by the FDA to use in selecting stroke patients for endovascular thrombectomy. It becomes the first imaging platform to receive such clearance for clot removal procedure, reported the creator of the technology, iSchemaView.

The American College of Cardiology (ACC) and several other partnering societies, including the American Heart Association and American Society of Nuclear Cardiology, released on Monday, Jan. 7 its 2019 Appropriate Use Criteria (AUC) for multimodality imaging of nonvalvular heart disease.

The Society of Cardiovascular Computed Tomography (SCCT) released updated guidelines for using CT imaging in patients undergoing transcatheter aortic valve replacement (TAVR).
