Magnetic Resonance Imaging can be used to provide structural and functional muscle information either from oxygenation or contraction imaging. Contraction imaging can be based on real-time imaging or on voluntary movements. However, synchronization of the acquisition is challenging. Here, we present a new method for accurate, quantitative measurement of muscle contraction using a commercially available electrical muscle stimulator. This allows the direct assessment of the reaction time of muscle fibers, contraction speed, displacement, and strain providing complementary information to electromyography. MR images of the vastus lateralis muscle of five healthy volunteers were acquired at 3 Tesla field strength during electro-stimulation.
