64 CT slices beat 16 for stenosis and diagnosis of heart disease

CHICAGO - Due to its superior z-axis resolution, 64-slice CT may do a better job than 16-slice in detecting in-stent stenosis, researchers reported on Sunday at the RSNA meeting. Another group found that 64-slice CT did not visualize vessels significantly better than 16-slice, but did improve diagnostic accuracy.

Cardiac CT strategies cut dose, keep image quality

By definition, symptomatic screening patients deserve the lowest possible CT dose. For that matter, "as low as reasonably achievable" (ALARA) is a wise dosing strategy for symptomatic heart patients, too. A look at the diagnostic question at hand and adherence to a few scanning principles can often reveal opportunities for significant dose savings, according to a recent presentation.

MRI differentiates AMI from myocarditis

Myocarditis or acute myocardial infarction? That is the question for some clinicians when emergency coronary angiography is normal. In fact it can be hard to distinguish the two very different heart problems. But MRI can provide a definitive answer, according to researchers in Paris, who employed early- and late-perfusion MRI sequences in their noninvasive protocol, and found significant differences between the two conditions.

Rather than develop a system with 128 or 256 detector rows, the company is launching what it calls dual-source CT -- a new design that uses two sets of x-ray tubes and detector arrays in a single CT gantry.
