Lumen area at CCTA predicts significance of stenosis
January 27, 2015 -- Measuring the minimal lumen area of coronary arteries scanned at coronary CT angiography (CCTA) can help distinguish lesions that are hemodynamically significant from those that are not, reducing the number of false positives, according to a new study by researchers from Austria.
Arab Health: Why CT really can rule supreme in coronaries
January 26, 2015 -- DUBAI - CT is now the gold standard for ruling out coronary artery stenoses and coronary anomalies. It can also be useful for coronary artery bypass graft and electrophysiology studies, as well as investigations of pulmonary veins, delegates learned on the opening day of Arab Health.
CT yields lower calcium scores in obese patients
January 23, 2015 -- Coronary artery calcium scores are underestimated significantly in larger patients compared with smaller ones -- enough to potentially alter their risk stratification, according to researchers from the Netherlands.
Ronald Grainger: Radiology loses one of its greats
December 23, 2014 -- When Dr. Ronald Grainger died in the autumn, radiology lost one of its greats. He was joint editor of the profession's "bible," Grainger & Allison's Diagnostic Radiology, and the first professor of radiology in Sheffield, U.K. Dr. Adrian Thomas pays a personal tribute.
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.
