Abstract:
Objective To investigate the changes of pulsatile tinnitus on HRCT and MRI CE 3D-SPGR image.Methods CT and MRI images of 1 5 pulsatile tinnitus patients were retrospective analysis.All 1 5 patients underwent temporal bone HRCT and MRI CE 3D-SPGR scan.Abnormal changes on CT and MRI image,which caused the pulsatile tinnitus,were compared.Results In 1 5 patients,9 sides (8 cases)showed abnormal sigmoid sinuses including 4 sides of sigmoid sinuses diverticulum,5 sides sigmoid sinu-ses uncovering,8 sides dominant sigmoid sinuses.The high jugular bulb was showed in 10 sides (8 cases),the thick emissaria mas-toidea in 5 sides (4 cases),bilateral semicircular canal dehiscence in one case,glomus tympanicum tumor in one case and the cochle-ar nerve was constricted by small vessel in one case.Conclusion Cranial base vessel abnormity can be visualized more precisely on MRI CE 3D-SPGR image than that on HRCT.On the contrary,the detection of temporal bone abnormalities is superior on HRCT.
