| مستخلص: | Purpose: To develop a self-gating method capable of assessing nonuniform motion, e.g., in cardiovascular magnetic resonance imaging of patients with severe arrhythmia, or for imaging of the temporomandibular joint. Methods: The proposed method allows cyclic motion trajectories with a nonuniform pace by replacing the one-dimensional gating signal of conventional image-based self-gating with a two-dimensional gating matrix. The resulting image quality is compared with conventional self-gating and real-time MRI. Results: Nonuniform self-gating resulted in superior image quality compared with conventional self-gating and the feasibility study showed significantly improved image sharpness (P < 0.01). Further, improvements in image quality were shown compared with golden angle radial parallel sparse MRI. Conclusion: A new self-gating method was proposed that allows cardiovascular magnetic resonance of arrhythmic patients, which is a common problem in clinical practice. Further, the proposed method enables self-gated imaging of the temporomandibular joint. Magn Reson Med 76:919-925, 2016. © 2015 Wiley Periodicals, Inc. (© 2015 Wiley Periodicals, Inc.) |
