Feasibility of 7 T 39K/23Na Magnetic Resonance Imaging for assessing muscular ion balance in hypokalemic periodic paralysis

Combined 39 K/ 23 Na MRI at 7 T demonstrated alterations of sodium and potassium ion homeostasis in HypoPP. These findings could be helpful for a better pathophysiological understanding of HypoPP and may aid in future studies to assess disease extent or monitor treatment efficacy.
