Nuclear magnetic resonance spectroscopy: its role in providing valuable insight into diverse clinical problems.
Skeletal muscle plays an important role in respiratory and cardiovascular physiology. The ability to measure metabolic changes in skeletal muscle has been enhanced with the advent of magnetic resonance spectroscopy (MRS). MRS measurements have been used to understand the metabolic control of respiration and to evaluate metabolic changes in the muscle in patients with respiratory and cardiac diseases. The key to the respiratory control measurements is the ability to measure intracellular pH with MRS. Muscle oxidative metabolism has been measured in two ways: during steady-state exercise and using recovery kinetics. The similarities in the metabolic findings for pulmonary and coronary disease suggest the potential for some interesting common pathways.
