The positive inotropic effect of epinephrine on skeletal muscle: a brief review.

abstract：INTRODUCTION:Similar to magnetic resonance imaging (MRI), electrical impedance myography (EIM) is dependent on the presence and location of water in muscle to assess neuromuscular diseases. We compared the 2 technologies in mdx mice to better understand their relationship. METHODS:EIM and MRI, using T2 relaxation and ...
