MRI Confirms Acupuncture Improves Brain Microstructure in Traumatic Brain Injury

A randomized controlled trial conducted at Xi’an Jiaotong University demonstrated that acupuncture significantly reduced postconcussion symptoms (PCS) in patients with mild traumatic brain injury (mTBI) and improved white matter microstructure as measured by diffusion tensor imaging (DTI). DTI is an advanced form of magnetic resonance imaging (MRI) that measures the diffusion, or movement, of water molecules in brain tissue. Unlike conventional MRI, which shows anatomical structure, DTI can detect microstructural changes in white matter tracts by mapping how water diffuses along axons. The study confirmed both short-term and long-term efficacy, establishing acupuncture as the only intervention in the trial to produce durable clinical and radiological benefits [1].
