[Abstract] In recent years, single-shotmagnetic resonance imaging (MRI) has been widely used in biomedicine, such as diffusion imaging, functional imaging, and real-time three-dimensional imaging, owing to its excellent temporal resolution. Among single-shot MRI approaches echo-planar imaging (EPI) stands out most. However, EPI still faces several limitations, particularly as a result of field inhomogeneity and of chemical shift effects that can become severein high fields. A novel single-shot MRI method was proposed based on spatiotemporal encoding, which provides a way to effectively alleviate the effects of field inhomogeneity and chemical shift while retaining high temporal-resolution character. In this work, we will review the principles and characters of spatiotemporally encoded MRI, and introduce the corresponding super-resolved reconstruction methods. In addition, we will present some major applications of spatiotemporally encoded MRI in biomedicine.
