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.

MRI identifies nerves capable of 'rescuing' muscle fibers

Although reaching old age is what many individuals hope for, experiencing muscle loss and frailty is not. However, a study recently published online in the Journal of Physiology may help increase clinical interest in developing methods to reverse muscle frailty and disability caused by old age.

CT imaging of children's bones may help produce safer car seats

By using medical imaging and computer simulated models, researchers at the University of Sheffield in England have recently tested the strength of children's bones to help manufacture safer car seats, toys and other infant and children targeted products, according to a recent article from Phys.org.

Non-hospital-based facilities offering cardiac imaging services a rarity in Massachusetts

In 2017, Anthem implemented a new policy that requires outpatient MR and CT scans not considered medically necessary to be completed at a freestanding imaging facility to receive coverage. This went into effect in several states, sparking its fair share of controversy along the way, and a team of Boston-based researchers wanted to know how such a policy could impact patient care in Massachusetts.

Microvascular dysfunction identified by innovative cardiac MRI techniques

A pair of studies published in the Journal of the American College of Cardiology found two novel forms of cardiac MRI that may accurately detect microvascular coronary artery disease (CAD) and cardiac microvascular dysfunction (CMD), according to a recent article by Cardiovascular Business.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
