    "abstract": "In this short review the results of detailed studies for dilepton production\nfrom $p+A$ and $A+A$ reactions at SIS energies are presented. The calculations\nare based on a semi-classical BUU transport model that includes the off-shell\npropagation of vector mesons and evaluates the width of the vector mesons\ndynamically. Different scenarios of in-medium modifications of vector mesons,\nsuch as collisional broadening and dropping vector meson masses, are\ninvestigated and the possibilities for an experimental observation of in-medium\neffects in $p+A$ reactions at 1--4 GeV are discussed for a variety of nuclear\ntargets.",
