Neuroimaging May Help Track Brain Volume in MS Patients

Since the LVV is anatomically distinctive and strategically located in the center of the brain, focusing on it provides a metric that is relatively immune to the adverse impacts of imprecise positioning, gradient distortions, incomplete head coverage, and other motion and wraparound artifacts.

The new tool simplifies the calculation of brain atrophy based on data from routine magnetic resonance imaging (MRI) scans, by comparing them to a database bank of 20,000 brain scans taken from of MS patients. The software runs on a user-friendly, cloud-based platform that is easily available from workstations, laptops, tablets, iPads, and smartphones. The software is specifically designed to work with low-resolution MRI scanners, such as those normally found in clinical practice.

Preliminary results presented at the American Academy of Neurology (AAN) meeting, held during April 2016 in Vancouver (Canada), show that NeuroSTREAM can provide a feasible, accurate, reliable, and clinically relevant method of measuring brain atrophy in MS patients. The researchers ultimate goal is to develop a user-friendly website to which clinicians can upload anonymous scans and receive real-time feedback on what the scans reveal. The study describing NeuroSTREAM was published in the July 2016 issue of Expert Review of Neurotherapeutics.

“Without measuring brain atrophy, clinicians cannot obtain a complete picture of how a patient's disease is progressing. Measuring brain atrophy on an annual basis will allow clinicians to identify which of their patients is at highest risk for physical and cognitive decline,” said lead author professor of neurology Robert Zivadinov, MD, PhD, of the Buffalo Neuroimaging Analysis Center. “Physicians and radiologists can easily count the number of new lesions on an MRI scan; but lesions are only part of the story related to development of disability in MS patients.”
