3D ultrasound goes ultrafast
November 11, 2014 -- Scientists in France have developed a new type of ultrasound that can produce 3D videos at thousands of frames per second. It builds on 2D ultrafast ultrasound, and has already enabled its creators to witness blood flowing through the chambers of a human heart in real-time.
CT values determine coronary stenosis severity
November 4, 2014 -- A novel technique developed in the Netherlands promises to determine stenosis severity in coronary CT angiography noninvasively -- and without the complexity of fluid dynamics calculations used in other noninvasive CT examinations, according to an article-in-press by the European Journal of Radiology.
German study lends support to rethink on chest pain
November 4, 2014 -- New analysis from Germany supports a dramatic change in the management of patients with ongoing chest pain and psychological problems after angiographic exclusion of heart disease. Its results call into question repeat or further investigative procedures.
JFR: At the heart of emergency care
October 21, 2014 -- Emergency medicine was a central theme during the French national radiology congress, the JFR, which ended on Monday. The cover story in the final edition of the daily newspaper focused on cardiac imaging and was written by Dr. Olivier Vignaux from Paris.
CCTA, not calcium score, predicts events in asymptomatic patients
October 16, 2014 -- Coronary CT angiography (CCTA) significantly outperformed coronary calcium scoring for predicting cardiac events in asymptomatic individuals, concludes an Austrian study presented at the recent European Society of Cardiology meeting in Barcelona, Spain.
Consent problems hold back fetal autopsies
October 15, 2014 -- Global researchers who are eager to gain experience in fetal autopsies using CT and MRI are facing immense frustration due to ongoing difficulties over obtaining consent, and one investigator reports being "hamstrung" by the procedures and bureaucracy of ethics committees.
Superfast LV assessment outperforms cine MR
September 29, 2014 -- A new sparse sampling MRI technique promises to speed up left ventricular (LV) volume and function assessments compared with the gold standard -- and to do so more accurately, according to a Swiss presentation at this month's European Society of Cardiology in Barcelona, Spain.
It's time to ditch your old gear, ESR says
September 22, 2014 -- Every healthcare facility or authority should have a plan for upgrading or renewing imaging equipment, and the plan should look forward at least five years and be updated annually, according to a statement issued on 18 September by the European Society of Radiology (ESR).
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.
