AI pinpoints 3 multiple sclerosis subtypes using thousands of brain MRI scans

Artificial intelligence has pinpointed three distinct subtypes of multiple sclerosis on brain scans that may enable more personalized patient treatment.

An international team of researchers trained their algorithm on more than 6,000 MS patients and validated it on another 3,000-plus individuals. They found cortex-led, normal-appearing white matter-led, and lesion-led subtypes each develop separately and respond to treatment uniquely, according to the study shared April 6 in Nature Communications.

Individual diagnoses can be directed to one of four treatment courses, but each is broadly based on the patient’s potential for relapse and future disability. These new subtypes will help researchers clinically define abnormalities to customize treatments.

"While further clinical studies are needed, there was a clear difference, by subtype, in patients' response to different treatments and in accumulation of disability over time,” Arman Eshaghi, a neurologist at University College London said to Science Alert. “This is an important step towards predicting individual responses to therapies."

RSNA and several other industry societies have shared a new expert consensus document on the significant value of cardiac CT. Echo remains an effective first-line imaging option, the groups wrote, but CT can make a big impact as well. 

"Using AI for tasks like CAC detection can help shift medicine from a reactive approach to the proactive prevention of disease," one researcher said.

Former American Society of Echocardiography president and well-known cardiac ultrasound pioneer Roberto Lang, MD, died at the age of 73. He helped develop 3D echo technology that is now used by care teams on a daily basis.
