Spiral CT Diagnosis of Small Amounts of Traumatic Suharachnoid Hemorrhage / 医学研究杂志

ABSTRACT

Objective To improve spiral CT diagnosis and differential diagnosis of small amounts of traumatic subarachnoid hemorrhage(TSAH).Methods SCT features of 105 cases with small amounts of TSAH , which were demonstrated by SCT reexaminations , were retrospectively analyzed. Results The distributions of small amounts of TSAH included cerebral longitudinal fissure cistern in 47 cases, cerebral lateral fissure cistern in 30 cases , cerebral surface sulcus in 22 cases, tentorium of cerebellum in 6 cases. There were 12 cases of small amounts of TSAH with contusion and laceration of brain , Subdural hematoma or bone fracture of skull.Conclusions Spiral CT scan has important value in qualitation and level diagnosisa of small amounts of TSAH.
