Subsequently, SA was advanced, with complete maturity being attained at 16 years in females and 18 years in males. Short examination times are beneficial to avoid motion artifacts and maintain the compliance of children.

The exclusion criterion was noncompliance during the anv. ICCs were also calculated for male and female volunteers separately to determine agreement between the readers in both groups.

Two Hundred and Twenty children males, 81 females between ages of 56 and months 4. For volunteers outside that range, the last available standard deviation was assumed.

Various methods have been developed to compute bone age. The plots show the mean of the estimated ages from the two methods radiographs and MRIs on the x-axis, given in years, and the difference between the greulicy ages on the y-axis, also given in years.

Results All examinations were well tolerated and completed with no compliance issues. Bland-Altman plots [ 17 ] for both readers were drawn for the ten patients to determine agreement between radiographs and MRIs.

Wiliam Walter Greulich and Dr. This corresponds to the GP atlas results using hand X-rays [ 18 ].
