Ultra-short echo imaging in the order of 100us achievable for clinical scanners allowed the detection of protons exhibiting very short T2 relaxation times, which is relevant for tendons, ligaments, or the periosteum. In this abstract, we proposed to use the Binomial pulse excite only the short T2 component and demonstrated that the new scheme helped for detecting fast relaxation tissues with the lower SNR that might be otherwise buried under various imaging artifacts.
