Association Between Intermittent Fasting and Susceptibility‐Weighted MRI Phase Values in Deep Gray Matter of Patients With Multiple Sclerosis: An Observational Cohort Study

Mahmoud R. Hamed, Yasser F. Ali, Mahmoud A. Kenawy, Mohamed El-Samahy et autres

BACKGROUND: One manifestation of multiple sclerosis (MS) is abnormal iron-related susceptibility changes in deep gray matter (DGM), contributing to oxidative stress and neurodegeneration. Intermittent fasting (IF) is a metabolic intervention that may influence inflammatory and iron-related pathways. PURPOSE: To compare susceptibility-derived phase …
