MRI of tissues with short transverse relaxation times can be performed efficiently with zero echo time sequences. However, in situation involving large dead time gaps, current established techniques such as algebraic ZTE, PETRA or WASPI are not optimal because of either point spread function-related artifacts or low SNR efficiency. In this work, a novel ZTE-based MRI technique is proposed. It employs a hybrid encoding scheme with both Cartesian and radial acquisitions. In this way, SNR efficiency is improved while preserving image quality as compared to existing methods.
