US: ultrasound; MRI: magnetic resonance imaging; GMH: germinal matrix hemorrhage; PVHI: periventricular hemorrhagic infarction; SWI: susceptibility-weighted imaging; T1/T2WI: T1-weighted/T2-weighted imaging; FLAIR: fluid-attenuated inversion recovery; DTI: diffusion tensor imaging; ADC: apparent diffusion coefficient.
