7T MRI matches 3T in right coronary artery imaging
October 20, 2010 -- Dutch researchers have concluded that in vivo human imaging of the right coronary artery at 7-tesla MRI equals or surpasses 3-tesla MRI, according to a study published in the October issue of Radiology.
CT calcium scoring alters cardiac risk estimates
October 14, 2010 -- Ten-year outcomes data from the Rotterdam coronary artery calcium (CAC) study underscore the prognostic power of adding CAC to a traditional risk stratification method. New results in the Journal of the American College of Cardiology show that CAC scores frequently change the risk category for future coronary events in asymptomatic individuals.
How to build a proton therapy facility
October 11, 2010 -- What are the essential requirements when setting up a new proton therapy facility? It's never a simple task. At a new facility under construction in Germany, stringent clinical requirements and technical specifications called for the implementation of several innovative technology developments.
MRI helps identify mild cognitive impairment
October 5, 2010 -- Using advanced MRI and an artificial intelligence technique, researchers in Geneva, Switzerland, have identified a method that may help identify which individuals with mild cognitive impairment will continue to decline, according to a study published online and in the December issue of Radiology.
European MRI advocates gain victory on EMF Directive
October 5, 2010 -- A controversial European Union law that potentially could threaten the use of MRI in research laboratories and medical clinics will be overhauled, clearing the way for the technology to continue being used across Europe, according to an accord announced last week by EU officials.
New CAD for COPD parses disease type, severity
October 1, 2010 -- Dutch researchers are taking computer-aided detection (CAD) of the lungs beyond suspicious lung nodules and into the diagnosis of chronic obstructive pulmonary disease (COPD), aiming to identify the patients most likely to benefit from treatment.
U.K. survey finds satisfaction with PACS, but issues linger
September 29, 2010 -- While the overwhelming majority of U.K. clinicians are satisfied with PACS, a number of thorny issues still need to be addressed, according to research published in the September issue of the European Journal of Radiology.
CAD detects signs of emphysema on DR images
September 27, 2010 -- Most of the recent research on the use of computer-aided detection (CAD) software for analyzing digital radiography (DR) studies of the chest has focused on lung cancer. But Italian researchers this month in European Journal of Radiology report good performance of an emphysema CAD algorithm that they developed at their institution.
MRI helps visualize elbow ligaments in asymptomatic subjects
September 27, 2010 -- Using certain pulse sequences, conventional 1.5-tesla MRI can visualize elbow ligaments that previously were not consistently visible in asymptomatic subjects, helping to diagnose patients with elbow instability, according to a study in the October issue of Radiology.
MRI can be used to follow great vessel stents
September 23, 2010 -- Using certain imaging sequences, MRI can be sufficient for the routine surveillance of certain great vessel stents commonly used to treat congenital heart defects in children and young adults, according to a study in the October issue of the American Journal of Roentgenology.
