Post-contrast imaging is useful for visualizing enhancing lesions, but when using MPRAGE at 7T the high vascular signal, gray/white matter contrast, and susceptibility-induced artifacts can confound visualization of enhancing lesions. T1-weighted SPACE imaging has been shown to provide improved visualization at 3T, but has not been used at 7T. Here, we show improved visualization of enhancing lesions at 7T with a T1 SPACE technique that avoids the downsides of post-Gadolinium MPRAGE imaging.
