Term Description

The latest Tanner and Whitehouse Method, sometimes referred to as TW2, involves the interpretation of a radiograph of the left hand and wrist by a trained radiologist. The procedure includes the assessment of regions of interest (ROI) on 20 bones. The ROI include the epiphysis, metaphysis and diaphysis of each bone. The radiologist gives each ROI a numerical score and records the result. The numerical score of each ROI is summed to produce a total score.
