3D PET can image brain oxygen metabolism October 17, 2014 -- A state-of-the-art 3D PET scanner can accurately image cerebral oxygen metabolism, as long as appropriate scatter compensation is carried out. In new work, researchers have demonstrated precisely how this can be achieved.
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.
Barco unites medical displays with Uniti launch at JFR October 16, 2014 -- In the world of medical displays, a gulf has existed between grayscale and color, with imaging facilities maintaining separate types of monitors for optimal performance. At the French national congress, JFR, Barco aims to bridge the divide through Coronis Uniti, designed for both applications.
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.
MIR: Communicate with patients or face being sued October 15, 2014 -- Failure to communicate effectively in the form of a triangle involving the radiologist, the referring physician, and the patient will result in more lawsuits, delegates were warned at this month's Management in Radiology (MIR) congress in Bologna, Italy.
Spanish dismiss digital mammo's overdiagnosis risk October 14, 2014 -- In a new 16-year study, Spanish researchers have found that switching to full-field digital mammography (FFDM) leads to early diagnosis, not overdiagnosis. The group found that cancer detection rates did not increase when compared with film-screen mammography, but going digital did lead to an increase in ductal carcinoma in situ detection rates.
New condensed JFR format faces acid test October 13, 2014 -- The French national congress of radiology, JFR 2014, begins in Paris on Friday and will take place over only four days, instead of the usual five. Emergency diagnostic and interventional imaging are the central themes of the congress.
RSNA to show x-ray 'nature scenes' by Dutch medical physicist October 13, 2014 -- What happens if you combine x-rays, creatures large and small, and a diorama? You get a "biorama," as Dutch medical physicist and artist Arie van 't Riet, PhD, has termed his images. His artwork will be shown at the upcoming RSNA 2014 annual meeting in Chicago.
Dual-energy CT develops greater role in brachytherapy October 10, 2014 -- A group of Canadian and Dutch researchers has developed a brachytherapy dosimetry method that accounts for dose heterogeneity. They have used dual-energy CT to extract these parameters, and the treatment is proving valuable in early stage prostate or breast cancer.
ASL-MRI detects early signs of cognitive decline in elderly October 9, 2014 -- Using arterial spin-labeled (ASL) MRI, Swiss researchers found evidence of cognitive decline in the brains of healthy elderly individuals before symptoms appeared, according to a new study published online on 7 October in Radiology.
U.K. radiographers opt to strike on 20 October October 8, 2014 -- For the first time in more than 30 years, radiographers in the U.K. public sector will take part in a national strike for four hours on the morning of Monday, 20 October. Also, nonurgent imaging procedures look set to be disrupted throughout that week.
