Fibromyalgia How Can You Diagnose Someone Else’S Pain
A new wave of research over the past 15 years has unlocked a number of potential biomarkers. The most notable new technique is functional magnetic resonance imaging (fMRI). Doctors scan the brain to measure differences in blood flow to tell which brain regions are active at a particular time. Some scientists, like Tor Wager at the University of Colorado, Boulder, and Vania Apkarian at Northwestern University, have begun to map out how acute and chronic pain appear in the brain using fMRI scans.
