  We summarize our results for hadronic contributions to the anomalous magnetic
moment of the muon ($a_\mu$), the one from hadronic vacuum-polarisation (HVP)
and the light-by-light scattering contribution (LBL), obtained from the
Dyson-Schwinger equations (DSE's) of QCD. In the case of HVP we find good
agreement with model independent determinations from dispersion relations for
$a_\mu^\mathrm{HVP}$ as well as for the Adler function with deviations well
below the ten percent level. From this we conclude that the DSE approach should
be capable of describing $a_\mu^\mathrm{LBL}$ with similar accuracy. We also
present results for LBL using a resonance expansion of the quark anti-quark
T-matrix. Our preliminary value is $a_\mu^\mathrm{LBL}=(217 \pm 91) \times
10^{-11}$.
