Physiological changes assessed with the MR technique:

• energy metabolism, in-vivo metabolic studies: 31P MRS, 13C MRS, determination of mitochondrial function, anaerobic and aerobic capacity, and glycogen metabolism
• lipid metabolism and deoxymyoglobin: 1H-MRS, tracking of intra- and extra-myocellular lipids and myoglobin
• blood oxygen level dependency = BOLD, monitoring of the oxygen supply within the tissue
• Perfusion MRI, microcirculation within the exercising muscle or the myocardium
• phase-contrast MRI, assessment of blood flow in the feeding vessel or changes in the tissue elasticity (cartilage, disks)
• CINE MRI, cardiac function, real time imaging of pressure-sensitive tissue like cartilage, ligamenta and disks
• Diffusion tensor imaging, fiber tracking in muscle tissue
• Relaxametry, determination of edema or water content in different tissues under stress (cartilage, ligamenta, muscle)

Diagnostic Pedal features:

• Fast and easy handling of the ergometer in daily clinical routines
• Cutting-edge technology for signal transmission without disrupting MR measurements
• Automatic recordings of all relevant parameters (e.g. force, distance, frequency and energy output).
• Fully automatic force adaptation powered by a pneumatic system and regulation of the energy output by user-friendly control software.
