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.

3D, 3T MRA demonstrates clinical value for PAD

A non-contrast time-resolved MR imaging technique promises to help interventional cardiologists treat peripheral vascular disease.

SNM: PET detects early signs of cardiac disease

PET imaging of asymptomatic individuals revealed coronary vasculardysfunction as a functional precursor of coronary artery disease,according to research presented during this week's SNM conference inNew Orleans.

SNM: Lantheus PET myocardial perfusion imaging tracer is well-tolerated

Preliminary clinical findings indicate that when used with PETtechnology, Lantheus Medical’s PET Myocardial Perfusion Imaging Tracerdemonstrates a favorable radiation dosimetry profile and is generallywell-tolerated, according to phase I data presented during the Societyof Nuclear Medicine (SNM) conference in New Orleans.

Ziosoft, Johns Hopkins to develop cardiac advanced viz applications

Ziosoft, a provider of advanced visualization and analysis software formedical imaging, is partnering with Johns Hopkins University inBaltimore, to explore innovative applications for cardiac CT and MRimaging.

CT angiography provides added advantage to children with great artery anomalies

Researchers in France found that 64-slice CT coronary angiographyperforms as well as invasive angiography to detect significant coronarylesions in children who have undergone the arterial switch procedurefor transposition of the great arteries. They also found that CTprovides information on the underlying mechanism of coronary luminalnarrowing.

Radiology: New coronary calcium measurement beats the tried-and-true approach

Calcium coverage scoring, which identifies the amount anddistribution of calcified plaque in the coronary arteries, may betterpredict a person's risk of heart attack than calcium burden alone,according to a multicenter study published in the June issue of Radiology.
