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.

SCAI 2015 Hildner Lecture Will Highlight Critical Need for More Clinical Research in Interventional Cardiology

New clinical research is essential to the development of hospital quality measurement, public reporting and pay-for-performance programs, according to Robert Harrington, MD, FSCAI, chair of the Department of Medicine at Stanford University School of Medicine, who will present the Society for Cardiovascular Angiography and Interventions (SCAI) 2015 Scientific Sessions Hildner Lecture, "The Future of Clinical Research in Interventional Cardiology: Challenges and Opportunities," on Friday, May 8, in San Diego.

Failing the stress test: Nuclear imaging AUC trip up some raters

As currently written, appropriate use criteria (AUC) for cardiac nuclear stress tests may not be as clear they need to be, according to a study published online Jan. 6 in Circulation: Cardiovascular Quality and Outcomes.

For transfemoral TAVR, contrast CT helps cut risk of vascular complications

Imaging with contrast CT instead of angiography to assess vessel diameter may lead to fewer transfemoral approach sheath-related complications during transcatheter aortic valve replacement (TAVR), a study published in the January issue of Circulation: Cardiovascular Imaging found.
