  We give a theoretical overview of the heavy quark tomography puzzle posed by
recent non-photonic single electron data from central Au+Au collisions at
$\sqrt{s} = 200$ AGeV. We show that radiative energy loss mechanisms alone are
not able to explain large single electron suppression data, as long as
realistic parameter values are assumed. We argue that combined collisional and
radiative pQCD approach can solve a substantial part of the non-photonic single
electron puzzle.
