Hyperpolarized 13C-labeled compound is an emerging technique in biomedical imaging to non-invasively detect metabolic processes and has been translated in clinical for cancer and cardiac metabolism studies. However, hyperpolarized MRI signal is limited by high spatial and temporal resolution and high SNR. This work describes a novel rotated Echo-planar imaging (EPI) trajectory with a half scan acquisition that shortens echo time to reduce the T2* effect in metabolic imaging. Compared to the standard full sampled EPI trajectory, the proposed trajectory has the advantage of gaining higher signal intensity, and is less sensitive to motion artifacts, distortion artifacts and aliasing artifacts.
