Study finds gadolinium-enhanced cardiac MRI often exceeded FDA guidelines
By Wayne Forrest
Tuesday, November 29 | 3:30 p.m.-3:40 p.m. | SSJ04-04 | Room S503ABA review of research from 2004 to 2010 has found that cardiac MRI studies routinely use higher gadolinium doses than recommended by the U.S. Food and Drug Administration (FDA) and clinical trials should be conducted to determine the appropriate doses of gadolinium enhancement of the myocardium.

Single dose of gadobutrol may be enough for cardiac MRI
By Wayne Forrest
Tuesday, November 29 | 3:20 p.m.-3:30 p.m. | SSJ04-03 | Room S503ABA study by Italian researchers suggests that a single dose of the MRI contrast agent gadobutrol is just as effective as a double dose of gadopentetate dimeglumine in cardiac MR imaging.

New MRI technique helps detect left ventricular myocardial scars
By Wayne Forrest
Monday, November 28 | 11:20 a.m.-11:30 a.m. | SSC01-06 | Room S502ABChinese researchers are giving high marks to a new free-breathing 3D phase-sensitive inversion recovery turbo FLASH pulse sequence for detecting left ventricular myocardial scars in patients with coronary artery disease.

ASE says it's happy with Definity label change
By AuntMinnie.com staff writers
The American Society of Echocardiography (ASE) said that it's pleased that the U.S. Food and Drug Administration has made positive revisions to the U.S. label for Lantheus Medical Imaging's Definity ultrasound contrast agent.

Myocardial perfusion stress CT moves to clinical use
By Eric Barnes
Tuesday, November 29 | 10:50 a.m.-11:00 a.m. | SSG02-03 | Room S503ABCardiac CT is ready for the comprehensive assessment of coronary artery disease in routine clinical use, say researchers from the Medical University of South Carolina. In the group's initial experience applying myocardial perfusion CT to a clinical population with acute chest pain, the technique detected myocardial perfusion defects just as well as the reference standards, MRI and SPECT.

CT approaches IVUS in plaque detection
By Eric Barnes
Monday, November 28 | 3:30 p.m.-3:40 p.m. | SSE03-04 | Room S502ABA study comparing CT to intravascular ultrasound (IVUS) for plaque detection found that CT isn't quite ready to take on ultrasound -- but it's not far off, the authors concluded.

CT equivalent to MRI in evaluating ventricular size, function
By Eric Barnes
Monday, November 28 | 3:10 p.m.-3:20 p.m. | SSE03-02 | Room S502ABVentricular size and function are important for diagnosing and managing patients with several conditions. Fortunately, dual-source CT has caught up to the reference standard, MRI, for the task, say researchers from the Medical University of South Carolina.

Monochromatic images erase beam-hardening artifacts
By Eric Barnes
Monday, November 28 | 11:10 a.m.-11:20 a.m. | SSC16-05 | Room S403BSynthesized monochromatic imaging with fast kV switching at 40 keV to 70 keV may boost the magnitude and uniformity of aortic enhancement for a wide range of body sizes, say researchers at Duke University.

Perfusion quantified in normal, infarcted myocardium
By Eric Barnes
Monday, November 28 | 10:50 a.m.-11:00 a.m. | SSC01-03 | Room S502ABA new CT study from the Medical University of South Carolina found significant differences in myocardial perfusion parameters for ischemic and infarcted myocardium compared with normal myocardium.

CCTA outpaces calcium scoring in acute chest pain
By Eric Barnes
Sunday, November 27 | 10:45 a.m.-10: 55 a.m. | SSA02-01 | Room S502ABThere is little value in coronary artery calcium scoring by itself in patients presenting with acute chest pain. In a head-to-head comparison, it's clear that only coronary CTA (CCTA) can replace angiography in diagnosing these patients, according to researchers from Italy.

Physicians with financial ties order more cardiac stress tests
By Eric Barnes
Physicians who stand to gain financially from nuclear stress tests or stress echo exams ordered more of the imaging studies for their patients as a follow-up to cardiac interventional procedures, concludes a new study published November 9 in the Journal of the American Medical Association.
