| Abstract: | Objective] To study the imaging features and the time-variation of diffusion weighted imaging(DWI) and apparent diffuse coefficient(ADC) at early stage of hypoxic-ischemic brain damage(HIBD)of neonatal pigs.Methods] The neonatal pigs were divided into 2 groups randomly:pseudo-operation group(n=8,as control group) and operation group(n=8).MRI was performed at a different time points of 0 h,1 h,3 h,6 h,9 h and 12 h after HIBD.DWI data were processed in GE AW4.4 to get ADC maps and ADC values.Results] Signi... |
