Ultra-high-field magnetic resonance imaging (MRI) provides detailed views of a brain area implicated in Parkinson's disease, possibly leading to earlier detection of a condition that affects millions worldwide. Parkinson's disease is a chronic, progressive disease characterized by shaking, stiffness, and impaired balance and coordination. With no radiologic techniques available to aid in diagnosis, clinicians have had to rely on medical history and neurological examination. It is often difficult to distinguish Parkinson's disease from other conditions using these methods alone.
