Use of positron emission tomography in the assessment of skeletal muscle and tendon metabolism and perfusion

Positron emission tomography (PET) represents the most advanced scintigraph ic imaging technology in humans, which allows non-invasive studies of metab olism and perfusion in vivo. PET has been employed for research of skeletal muscle physiology and pathophysiology as well, as for studies of effects o f training and exercise. PET is a functional research method, being a power ful tool, especially in studies of skeletal muscle perfusion in humans. It also provides a potential tool for studies of tendon physiology. In this re view examples of recent studies of skeletal muscle in athletes and during e xercise are given and potential applications of PET in the field of tendon studies discussed.
