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.

Cardiologist compensation barely keeps up with inflation

Specialty physicians’ overall compensation remained flat in 2007,(increasing just 0.31 percent, adjusted for inflation, or 3.16 percentwithout inflation), according to a report from the Medical GroupManagement Association (MGMA).

JACC: CCTA proves effective as noninvasive alternative to angiography

In chest pain patients without known coronary artery disease,64-multidetector coronary CT angiography (CCTA) possesses higherdiagnostic accuracy for detection of obstructive coronary stenosis thaninvasive coronary angiography (ICA), according to research publishedonline Aug. 22 in the Journal of the American College of Cardiology (JACC).

Researchers ID sources of error for CT-measured cardiac function

Despite the excellent spatial and contrast resolution of CT, themodality comes up a bit short when calculating left ventricular sizeand function compared with MRI. Researchers from the University ofChicago were able to explain why this happens and how to solve theproblem.

CT, MR equivalent in ED assessment of myocardial infarct

Cardiac imaging for myocardial infarct size in an emergency department(ED) is constrained by the difficulty of conducting MR or nuclearmedicine exams on unstable patients. However, using more widelyavailable CT technology shows promise as an alternative imagingtechnique that may provide similar information.

Virtual hearts help cardiologists plan treatment

Computer technology has been developed that enables clinicians tocreate computer models of the heart, which not only reflect theindividual anatomical make-up of the patient’s real organ, but can alsomimic accurately its movement as it beats.

FiatLux receives FDA clearance for advanced viz application

FiatLux Imaging has received FDA 510(k) clearance for the new releaseof Visualize, its medical imaging application, which is based on videogame technology, to create 2D/3D images from CT and MRI scans.

AJR: CT, MR equivalent in ED assessment of myocardial infarct

Cardiac imaging for myocardial infarct size in an emergency department(ED) is constrained by the difficulty of conducting MR or nuclearmedicine exams on unstable patients. However, using more widelyavailable multidetector CT (MDCT) technology shows promise as analternative imaging technique that may provide similar information.

AJR: CCTA is cost-saving for low-risk womennot men

Coronary CT angiography (CCTA)-based triage for patients with low-risk chest pain is modestly more effective than the standard-of-care, and it is also associated with cost-saving in women and low cost-effectiveness ratios in men, according to a study in the August issue of the American Journal Roentgenology.
