Abstract: Objective To evaluate the clinical value of susceptibility weighted imaging (SWI)in full-term neonatal hypoxic ische-mic encephalopathy (HIE).Methods Sixty-three neonates with HIE were collected and scanned by Siemens 3.0T superconducting MR scanner.Routine axial conventional MRI scan and axial SWI scan were conducted.Results In 63 neonates,a total of 29 cases with different degree of intracranial hemorrhage were scanned with SWI sequence.A total of 1 5 1 intracranial hemorrhages were found.Conventional MRI sequences were performed in 1 5 cases with different degree of intracranial hemorrhage.Only 78,43 and 88 hemorrhages were found by T1 WI,T2 WI and T2 Flair sequences,respectively.SWI were significantly superior to conventional MRI sequences in displaying the scope and boundary definition of hemorrhage.Conclusion SWI sequence is obviously better than the con-ventional MRI sequences in bleeding detection and displaying hemorrhage stove,and it provides a powerful imaging method for the clinical diagnosis and treatment.
