Relaxing times for cardiologists
February 25, 2015 -- The holy grail of diagnostic imaging is noninvasive tissue characterization and the external identification of human cell structures and organ function, if possible without even touching the body, according to the Maverinck. Relaxation times are key but controversial.
MRI with T2 mapping will aid myocardial edema diagnosis
February 17, 2015 -- Mapping T2 relaxation times in MRI is an important first step toward better diagnosis of myocardial edema. But T2 relaxation times vary widely, both being functions of MR sequences and scanner field strength, so basic studies will be required to access their value.
Use CTA for aortic emergencies, Austrians say
February 13, 2015 -- For detecting aortic emergencies, CT angiography (CTA) is the modality of choice and enables clinical teams to decide whether elective, urgent, or emergent treatment is necessary, while endovascular aortic repair (EVAR) and surgical repair are the recommended therapies, according to Austrian researchers.

Arab Health: 5 tips for handling diabetes foot problems
February 2, 2015 -- DUBAI - The creation of a dedicated service for diabetes patients with foot problems, in which interventional radiologists play a central role in limb salvage, is contributing to a dramatic reduction in the number of amputations in the United Arab Emirates.
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.
