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.

Radiology: Integrated lower extremity CTA feasible, effective in trauma cases

Integrating lower extremity CT angiography (CTA) into a multiphasic whole-body CT can help detect clinically relevant vascular injuries, decrease time to diagnosis and reduce the contrast load, according to a study published online Sept. 20 in Radiology.

ASNC explores past, future of nuclear cardiology

This years 16th annual American Society of Nuclear Cardiology (ASNC) scientific session, which took place last week in Denver, highlighted where the future of nuclear cardiology is headed, and what steps are necessary to make it flourish. While some presentations focused on how nuclear cardiology can stay afloat during the ambiguous era of healthcare reform, others focused on the need to eliminate inappropriate testing as a means to reduce radiation exposure, often the Achilles heel of imaging exams. 

Ultrasounds star is on the rise

Ultrasound recently received two thumbs up in separate reports, garnering attention as a lower-cost, lower-radiation dose modality.

Risk Assessment

Two recent studies demonstrated the efficacy of various nuclear cardiology techniques for assessing the risk associated with the extent of ischemia for varied cardiac patient populations.

Illuminating Contrast Media Management

As automated contrast injectors are increasingly utilized in cardiology departments, administrators are establishing protocols to lessen the incidence of contrast-associated adverse events, as well as improving the bottom line. Both goals, it seems, are interrelated.

Managing Heart Failure Through Nuclear Imaging

Recent data have shown that using both PET and SPECT may have the potential to provide clinically useful data to enable better stratification and favorable treatments for patients with heart failure.

The Back Page: ASNC Commits to Patient-Centered Care

ASNC President Leslee J. Shaw, PhD, reflects on how this months annual conference focuses on three aspects of patient-centered care: appropriate use criteria, comparative effectiveness research and radiation safety.

Circ: Scoring system predicts CCTA image quality

Researchers have developed and validated a weighted scoring system that incorporates patient- and scan-related factors to predict pre-coronary CT angiography (CCTA) risk of an uninterpretable result in symptomatic patients, according to a study published online July 26 in Circulation: Cardiovascular Imaging.
