Abstract:
Objective To investigate the metabolic alterations in the brain of neonates with HIE and correlate those alterations with clinical grading and prognosis of HIE.Methods Fourty-six eases of full-term neonates diagnosed as HIE clinically were performed MRI and 1~H-MRS,9 healthy neonates without the evidence of asphyxia were studied as controls,1~H-MRS techniques included single voxel proton MRS and two dimensional muhi-voxel chemical shift spectroscopy imaging,point resolved spectroscopy sequence was used for 1~H-MRS.Metabolic changes in the spectroscopy were analyzed in neonates with HIE,and study the relationgship between MRS findings and prognosis.Results(1)The typical 1~H-MRS manifestations of full- term neonates suffering from HIE were as follows:the peaks of Lac were elevated,GLx-? were elevated and NAA were decreased.(2)GLx-?/Cr ratio in control,mild,moderate and severe HIE group was 0.16, 0.21,0.64,and 1.31,respectively.Lac/Cr ratio in control,mild,moderate and severe HIE group was 0.12,0.14,0.19,and 0.26,respectively.There was a significant difference in the ratio of GLx-? and Lac/Cr between HIE group and control group(t=5.01,P
