The Optimal B Value In Diffusion-Weighted Magnetic Resonance Neurography Of The Brachial Plexus

Abstract

Injuries to the brachial plexus typically result from road accidents and occur most commonly in young men involved in motorcycle accidents [1]. Brachial plexus injury is a rare entity, often resulting in lifelong motor and sensory dysfunctions. Moreover, lesions in the brachial plexus may lead to chronic pain [2]. Over the past several years diffusion-weighted imaging (DWI) has been widely applied to a variety of conditions, including infarcts, tumors, and demyelinating disease of the brain. DWI enables noninvasive characterization of biologic tissues based on their water diffusion properties. Diffusion-weighted images are obtained by acquiring T2-weighted images with the addition of a diffusion weighting gradient; the strength of the gradient is
