Magnetic resonance evaluation of fibrovascular ingrowth into porous polyethylene orbital implant.
We assessed the fibrovascular ingrowth into porous orbital implant with MRI. Twelve cases underwent T1WI, T2WI, Gd-enhanced T1WI, and Short Tau Inversion Recovery (STIR) images. Gd-enhanced T1WI showed homogeneous enhancement (n=4), peripheral and posterior part enhancement (n=7), and anterior part enhancement (n=1) of implants. High signal intensity portions on STIR images coincided with the enhancing portions on Gd-enhanced T1WI. Gd-enhanced T1WI is an excellent method for assessment of fibrovascular ingrowth into orbital implant and STIR images may be a comparable method to Gd-enhanced T1WI.
