Step-and-shoot acquisition cuts CTA dose, improves images
By Eric Barnes
Low-pitch helical acquisition is effective for ensuring complete volume coverage and good phase registration over multiple cardiac cycles. But it packs a high radiation dose and lacks flexibility for irregular heart motion. Researchers have found a potential solution with a "step-and-shoot" acquisition mode for 64-slice CT scanners that can reduce even a modulated dose by 50% or more.

MDCT still can't differentiate between noncalcified plaques
By Eric Barnes
Thin-section multidetector-row CT does a fine job of visualizing calcified atherosclerotic plaque, but is all but blind when it comes to differentiating two important but morphologically distinct types of noncalcified coronary plaque.

MDCT equals MRI for RV function assessment
By Eric Barnes
Right ventricular (RV) parameters and function are known to have major prognostic import in patients with heart disease and chronic pulmonary embolism, but RV assessment can be challenging with CT, compared to the MRI gold standard. But researchers from Germany have found that 16-slice MDCT was statistically equivalent to cine MRI for estimating RV volumes, ejection fraction, and other important parameters.
