Simulation platform streamlines VR training July 18, 2016 -- Researchers are simplifying the creation of virtual reality (VR) surgical training modules with the development of a task-based approach to simulations training, according to an article in the International Journal of Computer-Assisted Radiology and Surgery.
Use MRI for athletes' acute groin pain, study finds July 15, 2016 -- As the Rio Olympics loom large, imaging of athletes is on the mind. A new study finds an MRI-based assessment approach for acute groin injuries shows good intra- and interrater reproducibility and may help improve clinician's confidence in scoring of these injuries.
Very low calcium scores do not guarantee negative MPI July 14, 2016 -- Symptomatic patients with very low coronary artery calcium scores are almost as likely to have a positive SPECT myocardial perfusion imaging (MPI) scan and a subsequent cardiac event as patients with higher calcium scores, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting.
Patient safety: MRI contrast use 'lacks consistency' July 13, 2016 -- There is no consistent approach to renal function assessment prior to administration of gadolinium-based contrast agents, even though international guidance does exist and consistency is vital to minimize risk and ensure safe practice, a new U.K. survey has found.
Combo MRI scans show how stomach tells brain it's full July 13, 2016 -- By combining anatomic MR images of the stomach with functional MR images of brain activity, Dutch researchers have shown how the stomach tells the brain it's full during a meal -- and how drinking more water can alter this communication channel.
Mobile App Spotlight: CMR Pocket Guide July 12, 2016 -- Cardiac MRI can be an intimidating modality to learn, but the CMR Pocket Guide aims to simplify tasks and can be useful both for education and in daily practice. We interviewed one of the app's co-developers, Dr. Bernhard Herzog from Lucerne, Switzerland.
Trends in shear-wave elastography: Where are we now? July 12, 2016 -- When it comes to the slow adoption of shear-wave elastography, clinicians tend to blame the glut of new technologies and the vast differences of quality and utility, but it's time for radiologists to make it a standard technique for assessing the liver, writes guest columnist Dr. David Cosgrove.
fMRI software falls short of expectations July 11, 2016 -- An extensive analysis of software commonly used for functional MRI (fMRI) has found false-positive rates of up to 70%, which may have adversely influenced the results of thousands of neuroimaging examinations, according to a Swedish/U.K. study.
Lancet study maps 2015 MERS outbreak in South Korea July 8, 2016 -- A single patient transmitted the Middle East respiratory syndrome coronavirus (MERS-CoV) to nearly half of those infected with the virus during the 2015 outbreak in South Korea, according to a study published online on July 8 in Lancet.
MR-guided radiotherapy progresses in lung July 8, 2016 -- By accounting for the presence of the magnetic field during treatment planning, it is possible to deliver clinically acceptable MR-guided lung stereotactic body radiotherapy treatments, report U.K. researchers. This result may pave the way toward improved radiotherapy treatments.
