64-slice CT outshines predecessors for imaging the coronary arteries

- 64-slice CTA overshadows MRA for coronary imaging.

- Earlier problems with calcification and ability to visualize distal coronary arteries have been largely solved with 64-slice imaging, but accurate characterization of distal branch narrowing remains a problem.

- Studies investigate role for multislice CT for triaging patients with acute cardiac syndrome in the emergency room as a complement to treadmill testing.

- Prevalence of incidental pathology on cardiac MSCT illustrates need for radiologist involvement in such studies.

- Steady progress continues in cardiac MR for myocarditis, pericarditis, and cardiomyopathy.
