Episode 9: How does magnetic resonance imaging help detect nervous system disorders?

05 Jun 2023

Magnetic resonance imaging (MRI) is a complex and powerful diagnostic tool in modern medicine. By expanding the capabilities of the technology and developing new magnetic resonance imaging techniques, Dr. Melanie Martin and her research team are hoping to improve the diagnosis and treatment of nervous system disorders like Alzheimer’s disease and Schizophrenia.

On this episode the research question is: “How does magnetic resonance imaging help detect nervous system disorders?”
