Susceptibility-weighted imaging in acute-stage pediatric XXXX .

@entity1 @entity410 @entity1211
BACKGROUND: The aim of this preliminary study was to investigate the clinical use of acute-stage susceptibility-weighted imaging (SWI) in @entity1 with prolonged @entity410 . METHODS: Ten @entity1 with prolonged @entity410 who underwent SWI within 2 h after termination of @entity410 (acute-stage SWI group) and 15 control @entity1 who underwent SWI >   2 h after their @entity410 terminated or for other purposes were enrolled. The cerebral venous vasculature was compared between the groups. The acute-stage SWI group was further divided into three subgroups: normal group, those with regional low signals in the cerebral veins (regional group) and those with diffuse low signals in the cerebral veins (generalized group). Inter-ictal electroencephalography (EEG) and venous blood gas findings during @entity410 activity were compared between these subgroups. RESULTS: All @entity1 in the acute-stage SWI group had low cerebral vein signal. Four @entity1 were assigned to the regional group and six @entity1 to the generalized group. @entity1211 and the increase of venous pCO2 during @entity410 activity was more prominent in the regional group than in the generalized group. In the regional group, low-signal areas in the cerebral veins were consistent with abnormal areas on EEG; these low-signal areas resolved completely in all @entity1 on follow-up SWI. Ten @entity1 in the control group had normal SWI, and five had a generalized low signal. CONCLUSIONS: Acute-stage SWI may be a useful alternative for identifying lateralization of @entity410 in @entity1 with prolonged @entity410 .
