Study on relationship between clinical grading and detection rate of hemorrhage by susceptibility weighted imaging for newborns with hypoxic-ischemic encephalopathy
摘要
Abstract
Objective: To study the relationship between clinical grading and detection rate of hemorrhage by susceptibility weighted imaging (SWI) for newborns with hypoxic-ischemic encephalopathy (HIE). Materials and Methods: 30 cases of newborns with HIE diagnosed by clinical criteria were selected to receive SWI sequence scan. These newborns were divided into 3 groups according to clinical grading (mild, moderate, severe) and numbers of newborns in which intracranial hemorrhage detected by SWI were counted.χ2 test and partitions ofχ2 method were performed to compare the detection rate of hemorrhage by SWI according to clinical grading. Results:There had statistical difference for the detection rate of hemorrhage by SWI among three groups (χ2=12.438, P=0.02). The detection rate of hemorrhage by SWI for mild newborns with HIE was signiifcant lower than that of moderate newborns with HIE (χ2=5.690, P=0.017) and that of severe newborns with HIE (χ2 =9.545, P=0.002). There had no statistical difference for the detection rate of hemorrhage by SWI between moderate and severe newborns with HIE (χ2=1.173, P=0.279). Conclusions:SWI has higher sensitivity than conventional MRI sequence in detecting intracranial hemorrhage. The detection rate of hemorrhage by SWI for mild newborns with HIE is lower than that of moderate and severe newborns. We can infer the severity in newborns with HIE according to whether hemorrhage was detected by SWI.关键词
