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.

Cinterion, TZ deliver arrhythmia monitoring device

Cinterion and TZ Medical have launched Aera-CT, a mobile health cardiac arrhythmia monitoring device.

ECRI alert focuses on monitoring cardiac patients

Cardiac monitoring enhances patient safety by alerting the caregiver to significant changes in the patient's cardiac status. But if the wrong patient is monitored, the late recognition of arrhythmias and delayed alarm response can lead to potentially avoidable deaths, according to an alert from ECRI Institute, a Plymouth Meeting, Pa.-based nonprofit that researches approaches to improving patient care.  

Echocardiography Enters Appropriate Use Spotlight

Tremendous attention has been focused on the overutilization of imaging, especially cardiovascular imaging. To counteract this trend, the cardiology and echocardiography communities have developed several new appropriate use criteria (AUC) documents since 2007, as well as a document that seeks to ensure quality in echocardiography laboratory operations.

Rb-82 PET gains traction in predicting CV events

While SPECT myocardial perfusion imaging is a well-validated noninvasive test to determine the presence of coronary artery disease, other tests are helping to fill in the gaps in identifying those at risk of cardiac events. In particular, measuring myocardial blood flow reserve with rubidium-82 (Rb-82) PET is finding its niche.
