Comparison of ultrasonography and computed tomography for measuring optic nerve sheath diameter for the detection of elevated intracranial pressure.
The main aim of this study was to compare optic nerve sheath diameter (ONSD) measured using ultrasonography (USG) and computed tomography (CT) almost simultaneously in the same patients with suspected elevated intracranial pressure. The other aim of this study was to evaluate the diagnostic ability for detecting elevated intracranial pressure using ONSD measured by USG (USG-ONSD) and by CT (CT-ONSD). ⋯ The ONSD measured using USG and CT were increased in patients with elevated intracranial pressure. Measurement of ONSD by USG and CT showed very high agreement.
