DTI-MRI shows how Wii can improve balance in MS patients
September 1, 2014 -- Using diffusion-tensor MRI (DTI-MRI), Italian researchers detected brain changes related to improved balance and movement in multiple sclerosis (MS) patients who regularly trained on a Nintendo Wii balance board for 12 weeks. Results were published online in Radiology.
MRI makes swift progress in research arena
August 29, 2014 -- Preclinical imaging is an increasingly vital research tool for observing organ, tissue, cell, or even molecular changes, and is often used while animals respond to physiological or environmental stimuli. Recent advances have escalated the quality and extent of preclinical research.
FLASH irradiation spares healthy tissue
August 28, 2014 -- Ultrahigh dose rate ionizing radiation delivered in submillisecond pulses causes less damage to healthy tissue, with comparable tumor control to that seen from the continuous irradiation used in clinical radiotherapy. That's the conclusion of a preliminary study by researchers in France.
Researchers dial back FDG activity to reduce PET/MRI dose
August 27, 2014 -- European researchers have set the groundwork for what they believe is a feasible way to achieve optimal image quality in PET/MRI scans: balancing lower radiotracer dose with prolonged PET image acquisition time to match the longer duration needed for MR image acquisition.
Shorter scan protocol could make breast MRI screening a reality
August 26, 2014 -- Breast MRI pioneer Dr. Christiane Kuhl has demonstrated that an abbreviated scanning protocol of just three minutes could make breast MRI a reality for population-based screening. The protocol worked well in a research study of more than 400 women that was published in the August issue of the Journal of Clinical Oncology.
Autosegmentation of head and neck CT aids treatment planning
August 25, 2014 -- Dutch researchers looked into automated segmentation of head and neck CT for treatment planning, and found it fast and accurate enough for daily clinical use -- dozens of times faster, in fact, than the manual technique it aims to replace.
Specialist certification gets easier in Germany
August 22, 2014 -- Changes to the training system are having major implications for radiologists in Germany. In this interview, Dr. Reinhard Loose, PhD, head of the Radiological Protection Commission Working Group of the German Radiological Society, discusses the certification requirements introduced in summer 2012.
Robot-assisted remote echocardiography shows promise
August 21, 2014 -- Can an ultrasound scanner be controlled robotically by an operator thousands of miles away? It's not just a dream, according to an international team of researchers who demonstrated the feasibility of robot-assisted echocardiography in a pair of articles published recently in JACC: Cardiovascular Imaging.
Conebeam CT pinpoints tricky scaphoid fractures
August 20, 2014 -- Conebeam CT is a highly effective, low-dose technique for detecting scaphoid fractures, and can demonstrate concomitant fractures that are notoriously difficult to see on radiographs, according to a prize-winning Belgian study presented at Europe's leading musculoskeletal congress.
Imaging reveals perils of world's oldest field game
August 20, 2014 -- New research conducted in the Irish Republic has highlighted the dangers of hurling, the world's oldest field game. In spite of more protective measures, musculoskeletal injuries remain common among young adults and are encountered frequently by the country's radiologists.
Long reports prone to speech recognition errors
August 19, 2014 -- Perhaps not surprisingly, long and complicated radiology reports that include many positive or unexplained findings have a higher risk for the presence of text errors mistakenly inserted by speech recognition software, according to research from National Health Service Grampian in the U.K.
U.K. group issues report on CT radiation dose
August 18, 2014 -- A U.K. government group has issued a report on CT radiation dose that documents the population's rising exposure to medical radiation, and makes recommendations for reducing the cancer risk from that exposure.
Interventional radiologists need to follow shielding protocols
August 15, 2014 -- Patients must be protected from unnecessary radiation exposure, but what about radiologists who perform interventional exams, particularly CT-guided procedures? German researchers found that radiologists have a low risk of overexposure -- if appropriate precautions are taken.
