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.

JASE: Two studies find carotid ultrasound bests Framingham risk scores

Screening young to middle-aged patients for carotid plaque or carotid intima-media thickness is likely to uncover cardiovascular risk in patients with a low Framingham risk score. In addition, carotid ultrasound proved better than a coronary artery calcium score via CT to predict risk, according to two studies in the August issue of the Journal of the American Society of Echocardiography.

SCCT: Computer-aided analysis for CAD detection shows promise

Computer-aided analysis (CAA) showed high sensitivity and high negative predictive value for the evaluation of significant coronary artery disease (CAD) on 64-slice cardiovascular CT angiography (CCTA) across three populations with differing CAD prevalence, suggesting that CAA could be used in clinical practice, based on a study presented this week at the fifth annual meeting of the Society of Cardiovascular Computed Tomography (SCCT).

Study seeks to settle clash between cards, rads on extracardiac CCTA findings

Almost one-fourth of all patients who underwent coronary CT angiography (CCTA) in a multi-center study had extracardiac findings; however, several serious diagnoses were missed with the limited viewing approach, but use of the broad viewing approach led to more workup and follow-up imaging, according to findings in the July issue in the American Journal of Roentgenology.
