Larry Husten, PHD

Computed tomographic angiography (CTA) enjoyed an explosion of growth over the past decade or more, fueled by enthusiasm for its ability to deliver speedy, high-resolution images of the coronary arteries.

ROMICAT-II Provokes Opposing Views on CT Angiography in the ED

Larry Husten, PHD

For patients with suspected acute coronary syndromes (ACS), CT angiography (CTA) compared to standard treatment can reduce the time in the emergency department (ED), according to results of the ROMICAT-II (Rule Out Myocardial Infarction/Ischemia Using Computer-Assisted Tomography) trial, published in the New England Journal of Medicine. However, CTA resulted in more tests being performed and increased radiation exposure. One […]

So […]

Now a new report published in JACC from the CORE-64 (Coronary Artery Evaluation Using 64-Row Multidetector Computed Tomography Angiography) study shows that CTA may not be […]
