Recently there has been rapid evolution of non-invasive techniques to quantitate bone mineral density. However, radiographic photodensitometry is useful and convenient in clinical situations. We evaluated the bone mass in healthy children using digital image processing method (DIP) and compared the results with bone age and radial bone mineral density (RBMD).Bone density of second metacarpus in 100 children without metabolic bone diseases were measured by DIP. Bone age was calculated according to Gleulich & Pyle atlas and RBMD was measured using single photon absorptiometry. The values of sigma GS/D and MCI increased with age, and those in females were slightly higher than in males. They were correlated well with chronological age, bone age and RBMD, and the most significant relation was seen between sigma GS/D and bone age.We concluded that DIP is a useful method for the evaluation of bone mass as well as bone maturity in growing skeleton.
