Can a CT scan show facial filler such as Juvederm Ultra Plus and Restylane?

I have a very small face and the PS injected 3 syringes of Juvederm and Restylane in just my cheek area. Not only was the filler too much but it was placed too high in my cheeks making my entire face look very different and wide. I have had 3 rounds of hylenex (150 units) to dissolve this.The PS insists that he has dissolved all of the filler but I am positive that the filler is still present.Therefore, I would like know if having a CT scan of the face is worth it to show any remaining filler.
