U.K. issues new advice on coronary CT angiography
December 16, 2014 -- The U.K. Royal College of Radiologists (RCR) has published recommendations for the safe use of coronary CT angiography to investigate patients with chest pain. The 26-page document can be downloaded for free from the RCR's website and includes practical information.
Motion casts bigger shadow than iterative reconstruction on calcium scores
December 3, 2014 -- CHICAGO - Fast-moving coronary arteries exert a huge influence on coronary calcium scores, but not all scores go in the same direction, according to new research from the University of Groningen in the Netherlands.
Radiation awareness: Where do we stand?
November 26, 2014 -- Knowledge of radiation dose and risk is poor among all radiology staff, but particularly among radiographers/technologists, and significant underestimation of dose and cancer risk is widespread, according to a new study.
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.
