Abstract: Systems and methods related to imaging biomarkers for determining neurological disease states of a subject are provided. In one embodiment, a method for producing an image indicative of a neurological disease using a magnetic resonance imaging (“MRI”) system is provided. The method includes directing the MRI system to perform a double inversion-recovery (“DIR”) pulse sequence to generate data where signals from gray matter and cerebral spinal fluid are substantially suppressed. The method also includes analyzing the DIR images, reconstructed from the acquired data, to identify cortical and white matter lesions. This includes identifying imaging biomarkers based on visual signatures of brain tissue, including white matter tissue. In some aspects, diffusion-weighted data may also be obtained using the MRI system.

Abstract: The present disclosure addresses the challenges of in vivo phosphorus imaging by providing a clinically useful phosphorus MRI (PMRI) system and method that may be performed on a standard MRI system in a clinically reasonable scan time using specifically tuned coils, a phosphorus pulse sequence, and improved reconstruction and post processing algorithms.
