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.

Pumping iron does a heart good—and MRI proves it

While the benefits of resistance training on musculoskeletal health are on daily display in any weightlifting room, the question of how much good all those sets and reps do for the heart has been open. Now comes an imaging-based answer from Germany, where researchers using MRI found measurable cardiac changes in a randomized group of novice male “gym rats” after they’d worked out regularly for around half a year.

Coronary CT angiography leads to questionably appropriate interventions

Acute chest-pain patients imaged with coronary CT angiography (CCTA) are more likely to receive revascularization and invasive coronary interventions that don’t clearly improve outcomes than patients evaluated with standard functional tests such as stress EKG and stress echocardiography, according to a meta-analysis of randomized clinical trials.

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.
