COMPARISON BETWEEN THE CT & MRI FOR MENINGIOMA IN THE BRAIN IN KING KHALID UNIVERSITY HOSPITAL RIYADH K.S.A

Purpose: To determine the diagnostic accuracy values of CT. Scan in the detection of meningioma in the brain. Correlated the accuracy of MRI with meningioma volume in (CC). Methods:Prospective study of Saudi both males & females patients of different age?randomly of 35 patients using CT. Scan axial, sagittal and coronal scans while in MRI Scan using standard protocol of examinations T1weighted image and T2 weighted image in all cases were examined. The results are classified in tables and using Chi-Square analysis. Results: Both CT. Scan and MRI exam?s can find meningioma lesion more than zero (cc). The table -7 Chi-Square test showing the P. Value =0.410 > 0.05 showing No. significant between the CT. Scan and MRI in finding the meningioma. Moreover, the table-10: Shows Chi-Square the P.value =0.008 > 0.05 showing significant in assessment of meningioma volume in (cc). Conclusion: Meningioma CT. Scan is useful examination in emergency patients. While MRI should always be considered as an indispensable imaging modality in the assessment of meningioma volume (cc). Both CT. Scan and MRI are used to support the diagnosis and evaluation of meningioma. But MRI is better in accurate diagnosis meningioma volume (cc).
