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.

AUC reflect imaging choices for stable ischemic heart disease

The American College of Cardiology and nine other cardiovascular societies issued updated Appropriate Use Criteria (AUC) for imaging in patients with stable ischemic heart disease, which now include ratings for all imaging modalities available to clinicians.

Early CT may predict favorable stroke outcomes

A tool that uses early computed tomography (CT) to quantify brain ischemia may effectively predict reperfusion and outcome in patients who suffer acute ischemic strokes, according to a study published online Dec. 12 in Stroke.

Pocket-size echo a practical, reliable diagnostic tool

The use of pocket-size echocardiography at a patient’s bedside can provide reliable diagnostic information, even if medical residents who perform the tests have limited ultrasound experience. In a study published in the December issue of European Heart Journal – Cardiovascular Imaging, researchers found that with three months of training, residents could obtain valuable information in less than six minutes.

Echo with contrast safer than without in critically ill patients

Although prior research has suggested a higher mortality risk in critically ill patients with the use of an ultrasound contrast agent (UCA) during echocardiography, a study published online Nov. 27 in the Journal of the American College of Cardiology: Cardiovascular Imaging found that UCA actually may be safer than no contrast at all.

Shopping for an ECG? Good luck

Hospitals appear to be more than willing to share price information with healthcare consumers, if the item of interest is a parking spot. But divulging costs on items such as an electrocardiogram (ECG) is another thing.

Siemens launches Artis one angiography system for universal use

At the 99th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), December 1-6 in Chicago, Siemens Healthcare (booth #1934, South Building/Lakeside Center at McCormick Place, Hall A) will introduce a new angiography system optimized for broad clinical utilization. Artis one¹ is designed for routine interventions, including revascularizations of peripheral arterial or venous occlusions, functional tests of dialysis shunts in patients with kidney failure, diagnostic angiographies of narrowed coronary arteries, and pacemaker implantations.

Researchers awarded 2013 Toshiba America Medical Systems/RSNA grants

The Radiological Society of North America (RSNA) Research & Education (R&E) Foundation awarded the 2013 Toshiba America Medical Systems/RSNA Research Seed Grant to Soterios Gyftopolous, M.D. and two 2013 Toshiba America Medical Systems/RSNA Research Resident Grants to Daniel S. Chow, M.D. and H. Benjamin Harvey, M.D., J.D. These grants are made possible by Toshiba America Medical Systems’ support of the RSNA R&E Foundation.
