[Abstract] Magnetic resonance imaging (MRI) is sensitive to detect hypoxic-ischemic encephalopathy (HIE). Conventional magnetic resonance imaging technology can accurately describe the vasogenic edema in the injured area of HIE, presenting as low signal on T1WI and high signal on T2WI. However, in the early stage of brain injury, there was no significant change in TIWI and T2WI for the cytopathic edema with only slight increase in brain tissue moisture. Compared with conventional MRI, magnetic resonance diffusion imaging based on the diffusion of water molecules can better reflect the microstructure of human tissue and the movement of water molecules inside and outside the cell, and it is easier to detect early HIE. The prospect of diffusion weighted imaging (DWI), diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) in the diagnosis of HIE is worth exploring.
