  In this paper, we consider the scattering theory of the radial solution to
focusing energy-subcritical Hartree equation with inverse-square potential in
the energy space $H^{1}(\mathbb{R}^d)$ using the method from \cite{Dodson2016}.
The main difficulties are the equation is \emph{not} space-translation
invariant and the nonlinearity is non-local. Using the radial Sobolev embedding
and a virial-Morawetz type estimate we can exclude the concentration of mass
near the origin. Besides, we can overcome the weak dispersive estimate when
$a<0$, using the dispersive estimate established by \cite{zheng}.
