Key Concepts

What is PET?

Positron Emission Tomography (PET) is a non-invasive imaging technique that uses radioactive tracers to visualize metabolic processes in the body. The main principle involves the emission of positrons from the decaying isotopes, which collide with electrons, resulting in gamma rays that are detected by the PET scanner.

Significance in Biomechanics

Within the realm of biomechanics, PET is instrumental in assessing various physiological functions such as:

• Muscle metabolism during physical activities.
• Understanding perfusion and metabolic disorders in tissues.
• Evaluating the effects of interventions in rehabilitation and sports medicine.
