In an expanding fireball model, we study dilepton production from high-energy heavy-ion collisions at the stopping regime. We find that the pion-pion annihilation gives the dominant contribution to the dilepton yield at invariant masses between 2{ital m}{sub {pi}} and 1 GeV. The total dilepton yield in this invariant mass region increases with the incident energy of the collision, but a saturation is seen once a baryon-rich quark-gluon plasma is formed in the initial stage.
