Abstract：Objective To compare the diagnostic efficacy of multi-slice spiral CT(MSCT)and MRI in acoustic neuro-ma.Methods The clinical data of 86 patients with acoustic neuroma treated from April 2019 to July 2021 were retrospectively analyzed.The diagnostic efficacy of MSCT,MRI and their combined examination in acoustic neuroma was compared,and the MSCT and MRI characteristics of acoustic neuroma were analyzed.Results The accuracy of MRI combined with MSCT in the diagnosis of acoustic neuroma was 95.35%(82/86),which was significantly higher than that of single MRI diagnosis[(84.88%(73/86)]and MSCTdiagnosis[(72.09%)(62/86)](P＜0.05).MSCT plain scan revealed similar round mas-ses,mostly uniform or slightly low density signal shadow,and enhanced scan revealed obvious enhancement,which can be uni-form,uneven or circular enhancement.Plain MRI revealed that cystic tumors showed high or slightly high signals on T1WI and T2WI,that solid tumors showed slightly low or low signals on T1WI and high or slightly high signals on T2WI,and that solid tumors showed low or slightly low signals on T1WI and high or slightly high signals on T2WI.The enhanced scan showed signifi-cant uniform and consistent enhancement of the tumor.Conclusion Both MSCT and MRI can display the imaging features of acoustic neuroma,and their combined examination can improve the diagnostic accuracy.
