TW2 Method for Bone Age Assessment: A Step-by-Step Guide

The TW2 method for bone age assessment is a process that involves the following steps:

1. 'Radiograph acquisition': A radiograph of the left hand and wrist is taken.

2. 'Image preparation': The radiograph is prepared by cropping and adjusting the contrast and brightness.

3. 'Bone selection': The bones in the hand and wrist that are used for bone age assessment are selected.

4. 'Bone age assessment': The selected bones are compared to a standardized atlas of bone development to determine the bone age.

5. 'Calculation of bone age': The bone age is calculated by comparing the selected bones to the atlas and determining the closest match.

6. 'Reporting': The bone age is reported in years and months.

In summary, the TW2 method for bone age assessment involves the selection of bones in the hand and wrist, comparison to a standardized atlas, and calculation of bone age. The bone age is reported in years and months.
