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.

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.

Vendors tout their success in 3D workstation face-off

It didn’t take long for workstation vendors to send out press releaseshighlighting their product’s success following the 3D workstationface-off at Stanford University’s 10th Annual Symposium onMultidetector-Row CT held in Las Vegas earlier this month.

JACC: Two experts diverge on CT imaging for CAD assessment

One side says there’s not enough evidence to justify incorporatingcoronary CTA into clinical practice to assess for heart disease. Theother side says the use of coronary artery calcium scores can helpstratify patients at intermediate risk of disease. Both commentaries inthe March issue of JACC Cardiovascular Imaging anchor themselves, albeit in different ways, to the Framingham Risk Score.

MRA-identified impaired coronary vasodilation indicates advanced CAD

Using MR angiography, researchers have found that impairednitroglycerin-induced coronary vasodilation was significantly andindependently associated with advanced coronary artery disease (CAD) inasymptomatic older patients, according to a study in the March issue ofJACC Cardiovascular Imaging.
