This study presents an IR sequence that enhances the border between two tissues of interest by employing an inversion time such that magnetizations of the two tissues have same magnitude and opposite sign, hence their interface results nulled and highlighted in the image by a dark line. The most obvious advantage of this technique is that it allows for immediate, enhanced visualization of borders between two tissues of interest without any additional postprocessing procedure, hence images are immediately visible to the neuroradiologist in real time. This technique is feasible on both standard and ultra-high field MRI systems.
