Bone Age Estimation for Whom by Whom? By Which Method?

Bone (skeletal) age determination is the simplest and most used index for the assessment of developmental and physiological age in healthy children and those with growth disorders. At present the test is done by manual or automated reading of the hand and wrist X-rays, necessitating two visits by the child: to the pediatrician and radiology departments. A newly developed simple quantitative ultrasound technique (QUST) using several hand and wrist bones, which can be performed in the pediatrician's office could combine the child's growth and biological age evaluation in one visit.
