Abstract：Objective To investigate the application value of CT detecting micro meningioma.Methods The clinical and imaging data of 20 micro meningioma patients was retrospectively analyzed.All patients underwent brain CT and MRI scans.The position,CT density,MRI signal of the intracranial meningiomas were observed and recorded.Statistical test was performed.Results Of the 20 micro meningiomas,12 cases had convexity of brain; 7 cases had the lesion in the midline close to the cerebral falx; 1 case was in the edge of the fight tentorium of cerebellum.Of the 20 micro meningioma,16 cases showed high or slightly high density (including 5 cases with calcification density) on CT images; 4 cases showed isodensity.Of the 8 cases with isointensity on MRI images,7 cases were high or slightly high density on CT images and only 1 case showed isodensity.The detection rate of CT was 80％.The detection rate of MRI was 60.0％.Conclusion CT has higher detection rate on the micro meningioma; the falx calcification meningioma can be misunderstood as falx calcification.
