Brain MRI shows lingering effects of concussion July 22, 2016 -- MRI scans of college athletes who have a history of concussion show changes in brain size, blood flow, and structural white matter months and even years after injury, according to a study published online July 21 in the Journal of Neurotrauma.
Machine learning may aid evaluation of prostate MRI July 20, 2016 -- Multiparametric prostate MRI exams can be difficult to interpret, particularly for those who aren't expert genitourinary radiologists. Machine-learning software may be able to make that task a lot easier, however, according to a proof-of-concept study from the University of California, Los Angeles.
Compact MRI developer targets clinical market July 15, 2016 -- Compact MRI technology developer Aspect Imaging is known for its presence in the preclinical MRI sector, but the company is now looking to break new ground. The Israeli firm has unveiled a 1-tesla hand and wrist system, the first in a planned series of dedicated clinical offerings.
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.
Coalition proposes MRI patient-safety blueprint July 14, 2016 -- With the goal of ensuring overall safety and patient care in the MRI environment, a coalition of international MR organizations has published a blueprint to guide the creation of three safety positions within radiology departments or imaging centers.
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.
fMRI software falls short of expectations July 12, 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.
Could machine learning diagnose Alzheimer's disease? July 7, 2016 -- Could techniques like machine learning help radiologists diagnose Alzheimer's disease? Dutch researchers used machine-learning software to analyze arterial spin-labeled MRI scans for signs of abnormal perfusion that could be a predictor of Alzheimer's, according to a study published on July 6 in Radiology.
JAMA: No link between gadolinium and parkinsonism July 5, 2016 -- There is some good news regarding the potential health effects of gadolinium-based contrast agents (GBCAs). Canadian researchers found no association between GBCAs for MRI scans and parkinsonism in a study published in the July 5 issue of the Journal of the American Medical Association.
