  We use our model for neutrino pion production on the nucleon to study pion
production on a nucleus. The model is conveniently modified to include
in-medium corrections and its validity is extended up to 2 GeV neutrino
energies by the inclusion of new resonant contributions in the production
process. Our results are compared with recent MiniBooNE data measured in
mineral oil. Our total cross sections are below data for neutrino energies
above 1 GeV. As with other theoretical calculations, the agreement with data
improves if we neglect pion final state interaction. This is also the case for
differential cross sections convoluted over the neutrino flux.
