Dynamic computerized tomography (CT) was performed on 42 @entity1 with @entity542 to evaluate the hemodynamics and to elucidate the nature of fatal @entity75 . @entity1 were divided into two groups according to the outcome: Group A included 17 nonfatally injured @entity1 , eight with @entity697 and nine with @entity6477 ; Group B included 25 fatally injured @entity1 , 16 with @entity6477 and nine with bilateral @entity75 . Remarkable @entity75 could be seen in all fatally injured @entity1 with @entity6477 . In 29 (69%) of 42 @entity1 , dynamic CT was performed within 2 hours after the impact. In the nonfatally injured @entity1 with @entity75 , dynamic CT scans suggested a hyperemic state. On the other hand, in 17 (68%) of the 25 fatally injured @entity1 , dynamic CT scans revealed a severely @entity63 state. In the fatally injured @entity1 with @entity6477 , CT Hounsfield numbers in the enlarged hemisphere ( @entity1410 side) were significantly lower than those of the opposite side (p less than 0.001). Severe diffuse @entity75 confirmed by follow-up CT scans and uncontrollable high intracranial pressure were noted in the fatally injured @entity1 . @entity75 following @entity542 originates from acute @entity2657 and an increase of cerebral blood volume. In cases of @entity542 , acute @entity2657 is the more common cause of @entity75 and occurs more rapidly than is usually thought.
