MR stress alone sufficient for myocardial perfusion
By
Eric Barnes
Use of an automated postprocessing tool eliminates the need for both a stress and rest exam in myocardial perfusion MRI, according to researchers from Germany. They found that quantitative assessment of stress MRI images alone delivers the same diagnostic performance as semiquantitative evaluation of both stress and rest perfusion exams.

Biological dose measures promise new view of cardiac imaging risk
By
Eric Barnes
The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.

Study: Endovascular repair can come first for AAA
By
AuntMinnieEurope.com staff writers
Researchers of a new U.K. study recommend endovascular or endograft repair as a first-line treatment for abdominal aortic aneurysm (AAA), given that the low reintervention rates are comparable to those reported for open surgical repair.
