Zero echo time (ZTE) imaging enables direct MRI of tissues with rapid relaxation, such as e.g. bone, tendons, or ligaments. Yet the feature of detecting signals from a wide T2 range is accompanied by a lack of contrast between the corresponding tissues. Therefore, in this work, efficient long-T2 suppression is developed for the ZTE technique. In this way, selective, direct musculoskeletal MRI akin to CT contrast is enabled and demonstrated in a tissue sample.
