The medium-induced modifications of the π+π- and [Formula: see text] annihilation mechanisms of dilepton production during relativistic heavy-ion collisions are considered in the frame of a specific model. The main assumption of the model: the pions (quarks) produced during a collision are effectively confined to a finite volume due to the dense hadron environment, in which they live for a finite time scaled as the lifetime of a fireball. The effect of the contraction of the phase space of the annihilating pion (quark) states on dilepton spectra is analyzed.
