a Graphical presentation of the signal-to-noise ratio (SNR) mean values and SD from 4 segments of the eye in the T1-w 3D-VIBE sequence. The mean SNR for the superior area of the ciliary body where the tumor was established displayed significantly higher value compared to the contralateral area. b Bar graph showing higher contrast-to-noise ratio (CNR) in the superior area of the ciliary body and thus a better discrimination in the targeted locus.
