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^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^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^LBL=(217 91) \times
10^-11\$.
