Radiographic evaluation of vascularity in scaphoid nonunions: A review

Figure 6 T1-weighted fat saturated pre-contrast, T1-weighted fat saturated post-contrast, and T2-weighted post-contrast sequences showing preserved vascularity in a proximal pole scaphoid fracture. There is a hypointense fracture line and diffuse marrow edema throughout the scaphoid. There is also hypointense T1 signal and hyperintense T2 signal with corresponding hyperenhancement on post-contrast imaging at the proximal pole, most intense in the proximal pole in keeping with preserved vascularity. FS: Fat saturated.
