We study QCD radiative corrections to the nucleon's transverse spin-dependent structure function {ital g}{sub 2}({ital x},{ital Q}{sup 2}) in the leading-logarithmic order for large {ital Q}{sup 2}. The anomalous-dimension matrix for the nonsinglet twist-3 operators appearing in the operator-product expansion for {ital g}{sub 2}({ital x},{ital Q}{sup 2}) is calculated and the experimental implications are discussed.
