Medium-induced gluon radiation is known to be of crucial importance to describe the properties of the quark-gluon plasma produced in heavy-ion collisions. I will show a flexible method which allows us to evaluate the full in-medium spectrum, including the resummation of all multiple scatterings, without the need of the approximations usually employed in the well-known analytical calculations. This framework is not only suitable for phenomenological applications, but also to analyze the validity of the analytical approaches. In this regard, I will use our all-order result to decipher in which regions the effects of multiple scatterings become essential and where, in contrast, a single hard scattering is enough to describe the in-medium emission process.
