Study: Reduce CT kV levels to lower breast dose in patients
December 7, 2016 -- Despite a short scan length and relatively small dose length product (DLP), contrast-monitoring scans can account for 27% of the overall breast dose accrued from a CT pulmonary angiography (CTPA) study, according to Irish researchers. A small tweak to the kilovoltage (kV) can significantly reduce radiation dose to the breast, they noted.
U.K. releases new guidance on chest pain
December 6, 2016 -- The U.K. National Institute for Clinical Excellence published its long-awaited update to the chest pain guidelines on 30 November, with leading cardiac imaging specialists issuing a positive, but cautious, response to the new document.
An occasional drink doesn't hurt coronary arteries
November 30, 2016 -- CHICAGO - Having an alcoholic drink once or twice a day does not appear to affect the coronary arteries, based on scans with coronary CT angiography, researchers reported on 29 November at the RSNA annual meeting.
Going Dutch means far more than tulips, Rembrandt
November 29, 2016 -- Tulips, Rembrandt, and free cookies feature prominently at the Netherlands Presents booth at McCormick Place in Chicago, but RSNA 2016 delegates found out during a special session why the country's neuroradiologists, including Dr. Meike Vernooij, PhD, are the real stars at the congress.
Cardiologists put renewed focus on dose awareness
November 18, 2016 -- New efforts are underway to increase dose awareness among European cardiologists, but dose-optimization advocates face a very long road ahead before every cardiologist who uses radiation has sufficient understanding of dose to protect himself and his patients, according to new commentary.
Report: Radiologist shortage grows in Europe
November 15, 2016 -- Further evidence has emerged of the increasing skills shortage across Europe. The population pyramid of radiologists in France could be seen as a ticking time bomb, while growth rates of CT and MRI in Sweden have continuously exceeded growth rates of practicing radiologists.
4D CT of subtalar joint aids ankle instability assessment
November 15, 2016 -- Dynamic quantitative CT with a 320-detector-row scanner of the subtalar joint offers detailed analysis of joint motion with a tiny radiation dose, revealing strong potential for the assessment of ankle instability, the authors of a new study conclude in the American Journal of Roentgenology.
Achenbach gives cardiologist's view on coronary CTA
November 9, 2016 -- LONDON - A leading cardiologist's perspective on the current clinical controversies surrounding coronary CT angiography (CCTA), as provided by Dr. Stephan Achenbach, was the main crowd-puller at last week's annual conference of the British Institute of Radiology.
Manual image thresholding still better for 3D printing
November 8, 2016 -- Automated segmentation algorithms that prepare CT images for 3D printing haven't advanced to the point where they can outperform humans setting threshold levels manually, concluded new research from Amsterdam in the International Journal of Computer Assisted Radiology and Surgery.
Day 1 pancreatic CT scans can fool clinicians
November 7, 2016 -- In a suspected case of acute pancreatitis, it's essential to use CT at the right time, a Dutch expert told delegates at the British Institute of Radiology annual conference on 4 November. CT is best performed at least 72 hours after symptom onset, said Dr. Thomas Bollen from Utrecht.
