PET/CT network expands in Russia
October 10, 2016 -- A new PET/CT network in Russia promises to make the technology more accessible, but stern challenges remain in a country that up to seven years ago only had 10 PET/CT scanners across a few major cities, said PET-Technology board member Diana Kobesova.
Head CT algorithm a step toward faster stroke care
October 7, 2016 -- Using automated software to interpret head CT scans could someday slash the time emergency doctors need to start clot-busting treatments in cases of suspected ischemic stroke, according to Dutch researchers.
Success of urgent neck CTA rests on patient selection
October 6, 2016 -- The usefulness of neck CT angiography (CTA) in trauma cases is restricted by its cost, radiation dose, and contrast side effects, so careful clinical evaluation of potential candidates based on the internationally accepted criteria is essential, according to new research.
Abstinence before prostate MRI offers benefits in over 60s
October 5, 2016 -- Abstinence from ejaculation prior to a prostate MR examination significantly increases the volume of seminal vesicles (SVs), and thereby may well improve evaluation of SV invasion on multiparametric MRI, especially in older men, according to new research from Turkey and the U.S.
Pushing the field strength boundaries in MRI
October 4, 2016 -- Pushing the magnetic field boundaries of MRI is not a spectator sport but a steam engine for innovation, and the high-field enthusiasts are blessed with the speed gain, sensitivity advantage, and breadth of MR applications empowered by breaking new ground, according to a new guest column.
Rat study finds no brain abnormalities from GBCAs
October 4, 2016 -- An evaluation of two linear gadolinium-based contrast agents (GBCAs) showed no signs of abnormalities in the brains of rats despite the presence of gadolinium. What's more, researchers found that gadolinium levels had decreased markedly 20 weeks after GBCA injection, according to results published online September 27 in Radiology.
How do we measure molecular imaging's cost-effectiveness?
October 3, 2016 -- Assessing the cost-effectiveness of molecular imaging is more about economics than medicine, according to David W. Lee, PhD, of GE Healthcare. The real benefits for society depend on the cost of the technology and the value people place on their health, he said at last week's symposium in Brussels.
Maniawski: We must sell molecular imaging better
September 30, 2016 -- Molecular imaging can drive personalized medicine and revolutionize healthcare, but unless the nuclear medicine sector improves its communications and outreach, it could be years before we see the benefits, Piotr Maniawski of Philips Healthcare told a symposium in Brussels on Wednesday.
Dose-monitoring software proves value in trauma cases
September 29, 2016 -- Automatic radiation dose monitoring software is feasible and accurate for monitoring CT doses for trauma patients, Swiss researchers have reported in Clinical Radiology. They also judged it to be quite useful for assessing the impact of dose-reduction initiatives over time.
Ghost imaging could lead to lower x-ray doses
September 29, 2016 -- Ghost imaging generates images by analyzing correlations between two light beams, the more powerful of which doesn't bounce off the object in question. The technique has been demonstrated at visible and infrared wavelengths, but now two international groups have extended it to the x-ray region.
