The application of ionizing radiation without medical
indication is prohibited in many countries. Thus, for
the application in age assessment (i.e., in criminal
proceedings and sports regulations) the Dvorak method
based on MRI of the wrist was developed as an
alternative to the standard X-ray based methodology
according to Greulich&Pyle, and is regularly used by the
FIFA for age testing in adolescent soccer athletes. The
accuracy of both methods was evaluated in volunteers
comparing estimated with chronological age. While
Greulich&Pyle was quite accurate, Dvorak showed a great
systematic deviation and cannot be recommended for age
estimation.
