Phase-contrast x-rays image the airways
September 18, 2014 -- Phase-contrast x-ray imaging offers a noninvasive way to track the effectiveness of cystic fibrosis treatments. The technique, which measures the refraction of a grid pattern of x-rays passing through the lungs, may eventually find use in visualizing other soft tissues, such as the brain and heart.
PET/MRI shows noninvasive imaging power in MI
September 9, 2014 -- PET and MRI each bring advantages for imaging myocardial infarction (MI) and gauging myocardial viability. So it makes sense to do them both in a single exam, concludes a study of 25 MI patients presented last week at the European Society of Cardiology congress in Barcelona, Spain.
ESC: Wireless ultrasound boosts image-guided venous access
September 5, 2014 -- Momentum is building for ultrasound-guided venipuncture, not least because using a wireless probe can transform practice, according to researchers from Madrid who presented their results at this week's European Society of Cardiology (ESC 2014) annual meeting.
ESC: Imaging of ischemia divides opinion
September 3, 2014 -- Is cardiovascular MR better than SPECT for imaging of ischemia? That was the burning question in a debate at this week's annual meeting of the European Society of Cardiology (ESC) in Barcelona, Spain, but the answer still eludes experts, it seems.
Robot-assisted remote echocardiography shows promise
August 21, 2014 -- Can an ultrasound scanner be controlled robotically by an operator thousands of miles away? It's not just a dream, according to an international team of researchers who demonstrated the feasibility of robot-assisted echocardiography in a pair of articles published recently in JACC: Cardiovascular Imaging.
Beyond cancer: Novel radiotherapy targets
August 14, 2014 -- Radiation therapy is a mainstay treatment for a wide range of cancers. But, according to German researchers, radiotherapy could also prove promising for treating conditions such as atrial fibrillation or hypertension.
U.K. team scoops top prize for chest wall deformities study
July 24, 2014 -- Developing a keen awareness of the radiological features of congenital chest wall deformities is a useful clinical skill, and imaging can also illustrate pre- and postsurgical appearances for more conditions requiring surgical correction, according to award-winning research from a top facility in London.
New-generation dual-source CT heart scans prove fast and sharp
July 22, 2014 -- Operating the new third-generation dual-source CT scanner 24/7 has revealed a rapid system with robust imaging capabilities and an array of new features to perform heart scans at low doses, according to researchers from a leading German facility.
'Tiered' CT approach shows promise in coronary disease
July 22, 2014 -- In patients with stable angina and suspected coronary disease, a "tiered" approach to CT imaging finds -- so far at least -- that calcium scoring is all many patients need. That's right, for most patients there's simply no need to start with the big imaging guns, researchers in Rotterdam report.
Rotterdam group helps gauge coronary disease severity
July 14, 2014 -- At the same time that a validated fractional flow reserve CT angiography application seems to be nearing U.S. Food and Drug administration approval, a new contender for gauging the severity of coronary disease at CT is pushing its way into the ring. Furthermore, it promises to be a simpler solution, according to a team of Dutch researchers.
Medical detective work: Identifying the unidentified
July 10, 2014 -- Nothing happens without interdisciplinary cooperation at Marburg University Clinic's new Unidentified Diseases Centre in Germany. Dr. Annika Keulers explains about the fascinating work going on in the facility.
Congenital heart defects concern every radiologist
June 6, 2014 -- Important changes in the epidemiology of congenital heart defects are taking place, which mean these defects no longer concern only pediatric radiologists and pediatric cardiologists because an increasing number of cases occur within the adult population, according to new analysis from Austrian experts.
DWI MRI boosts edema detection in acute myocarditis
June 3, 2014 -- Diffusion-weighted MRI (DWI) is similar to -- and probably a little better than -- conventional black blood short tau inversion-recovery MR images when it comes to detecting edema in patients with myocarditis, the authors of a new study from Spain have found.
DRK: Cardiac MRI can provide clear picture on chest pain
June 3, 2014 -- When patients arrive in an accident and emergency department showing symptoms of a myocardial infarction, a catheter-based examination may be inconclusive, but nine times out of 10 MRI will lead to the correct diagnosis, according to a study presented at last week's 95th congress of the German Society of Radiology (DRK).
Correct MRI safety protocols bring success with pacemakers
May 21, 2014 -- MRI exams of patients with pacemakers can be performed safely when proper device programming and monitoring are adhered to, and there do not appear to be major differences between the results of MR-conditional and MR-unsafe devices, Finnish researchers have found.
IARCA anomalies rare, but often signal other cardiac problems
May 19, 2014 -- Intra-atrial right coronary artery (IARCA) anomalies are rare, but when detected at coronary CT angiography, they often indicate the presence of other cardiac anomalies, according to a new Polish study published in the European Journal of Radiology.
