33 MedTech Spotlight News Artificial Intelligence to Assess Dementia Risk and Enhance the Effectiveness of Depression Treatments Even though EEG is the most used brain imaging technique in the world, magnetoencephalography (or MEG) - which measures the magnetic fields generated by the brain’s electrical activity - provides signals that are easier to interpret than EEG, because the skull and other tissues don’t distort magnetic fields as much. Researchers from Aalto University in Helsinki tell us that MEG coupled with AI shows that communication between neurons begins to deteriorate well before the initial clinical symptoms of dementia. Inversely, magnetic stimulation is used to treat severe depression and neuropathic pain. Read More MRI findings associated with poor thrombectomy outcomes after stroke Recent research published in Radiology (based on the MRI brain scans of 366 patients after endovascular thrombectomy - EVT ) found that as the presence of white matter hyperintensity (WMH) volumes increased, so too did patients’ risk of poor three-month poor post-procedure clinical outcomes. The scientists from Montpellier in France believe that there is apresumed relationshipbetween vascular origins and cognitive dysfunction, depression, increased risk for stroke, higher rate of disability and death after stroke, which suggests that patients with increased WMH burden might respond less favorably to EVT. Read More O-RADS Externally Validated for Differentiating Between Benign and Malignant Ovarian Lesions Another article from the good folks at HealthImaging.com . Researchers from the Department ofMedical Imaging at the University of Toronto recently completed an external validation for the Ovarian-Adnexal Reporting and Data System (O-RADS) for classifying lesions as malignant or benign, for which validation had been previously lacking. To the authors’ knowledge, there are no current studies that have examined the system’s efficiency at distinguishing between malignant and benign lesions using surgical and nonoperative treatment as the reference standard. Ultrasound were conducted by sonographers in North America. Read More Medical Imaging News has found great new stories, written somewhere else by somebody else.
