Dutch use registration scheme to tackle 'missing structures'
August 1, 2014 -- Adding a geometrical penalty term to a nonrigid registration algorithm allows registration of structurally dissimilar medical images, according to new research from Utrecht in the Netherlands.
New workflow for knee MRI can boost efficiency
July 31, 2014 -- Prize-winning researchers from Pamplona, Spain, have devised a practical system for reading knee MRI scans that can help to improve efficiency, both in terms of speed and accuracy of detection of knee pathology. It may prove particularly beneficial for newcomers to the field.
Honey, I shrunk the magnet: 7T MRI runs cryogen-free
July 29, 2014 -- Looking to fill a void in the market for preclinical MRI and eliminate the need for labs to hunt down scarce supplies of liquid helium, MR Solutions has developed a new cryogen-free, compact 7-tesla scanner for research applications. The system generated great interest at the global MRI congress held in Milan, Italy, during May.
Scots get set for Usain Bolt, Mo Farah, et al
July 23, 2014 -- The Commonwealth Games begin today and is the largest sporting event ever held in Scotland. Musculoskeletal radiologist Dr. David Ritchie and his team of volunteers are prepared for everything and have already been keeping busy in the state-of-the-art polyclinic in Glasgow.
MRI links antipsychotic drugs to brain loss
July 21, 2014 -- MR images of patients with schizophrenia have confirmed that antipsychotic drugs can lead to a decrease in brain volume, but the drugs do not appear to cause adverse cognitive issues. The study also found that the rate of brain loss was greater when the dose of medication was higher.
Dutch use shimming to enhance value of MRI-linac unit
July 17, 2014 -- Only a handful of groups are developing hybrid MRI-linac systems for cancer treatment, but interest in this area looks set to grow after researchers from the Netherlands showed that shimming allows a system to acquire images with good geometric fidelity for all static gantry positions.
French MRI waiting times are 'worst in a decade'
July 16, 2014 -- The shortage of MRI equipment in France is becoming increasingly alarming, and many patients have to wait almost 40 days to undergo an examination, the longest delay in the past 10 years, according to new data. This report highlights a disaster, said a respected senior radiologist from Paris.
MRI use linked to patient mortality in Irish study
July 15, 2014 -- A new study of MRI use at a hospital in Ireland paints a complex picture of the modality, with higher in-hospital mortality and longer hospital stays for patients who got MRI scans. However, this could be because the patients were more acutely ill, according to an article in the July Journal of the American College of Radiology.
Optical monitoring assesses HIFU damage
July 4, 2014 -- Measuring changes in tissue optical properties could provide a low-cost method for monitoring high-intensity focused ultrasound (HIFU), according to new research from the U.S. and U.K. It's a promising noninvasive alternative to open surgery.
Claustrophobia, MRI, and the human factor
July 2, 2014 -- In MRI, claustrophobia is a concrete fear haunting many people. Norwegian researchers think a set of simple, practical steps can help address the anxieties of patients, saving valuable time and avoiding repeat examinations. The Maverinck explores this topic.
Web-based liver imaging atlas scoops top award at ESGAR
June 25, 2014 -- An e-learning tool run by radiologists in Switzerland and the U.S. received the only Magna Cum Laude at last week's European Society of Gastrointestinal and Abdominal Radiology (ESGAR) congress. The Liver Imaging Atlas now has 22,000 users, and 26% of user traffic comes from Europe.
Norway acts to improve workflow and cut dose
June 25, 2014 -- A pioneering 50,000 euro project that began in the scenic west of Norway in April aims to organize imaging protocols so that examinations can be exchanged efficiently between hospital groups. The scheme is seen as a necessary step to optimize workflow and protect patients from excess radiation exposure.
ESGAR: Imaging sheds light on tumor response in liver
June 24, 2014 -- Evaluation of treated hepatic lesions is challenging, so it's vital to adapt the imaging strategy and evaluation criteria according to the treatment used and underlying tumor, noted award-winning French researchers at last week's European Society of Gastrointestinal and Abdominal Radiology (ESGAR) meeting.
Be creative on tech assessment, DRG president urges
June 16, 2014 -- A critical challenge is how to assess the influence of every imaging procedure with accuracy and rigor. Dr. Norbert Hosten, president of the German Radiological Society (DRG), thinks there's a big opportunity to exploit the potential of new scientific participation in fresh and original ways.
UKRC: How to achieve success with fetal MRI
June 12, 2014 -- MANCHESTER - There's a great need to optimize and standardize patient care and imaging parameters to realize fetal MRI's potential, avoid unnecessary repeat examinations and improve image quality and efficiency, according to research presented at this week's U.K. Radiological Congress (UKRC).
Congenital heart defects concern every radiologist
June 6, 2014 -- Important changes in the epidemiology of congenital heart defects are taking place, which mean these defects no longer concern only pediatric radiologists and pediatric cardiologists because an increasing number of cases occur within the adult population, according to new analysis from Austrian experts.
