2D Turbo gradient and spin echo BLADE diffusion-weighted imaging (TGSE-BLADE-DWI) has been shown to improve image quality by reducing geometric distortions and susceptibility artifacts for middle ear cholesteatomas and optic neuritis; however, its use in depicting orbital tumors is still unknown. The results of this study demonstrated that TGSE-BLADE-DWI could provide significantly better image quality and comparable diagnostic performance for characterizing orbital tumors.
