    Meningioma, is the second most frequent intracranial tumor in Malaysia and are classified according to the World Health Organization classification. The relationship of p53 protein in the determination of meningioma grading and their influencing factors were studied via immunohistochemistry studies on 77 intracranial meningiomas (67 benign, 10 atypical). The higher the p53 reaction was correlated to the poorer the histological grade (19.4% in benign and 90% in atypical meningioma) (p < 0.001). Other variables like age, sex, ethnicity, demographic location, surgical clearance, midline shift and contrast enhancement of CT Scan Brain and clinical features were found not to be significant.

    OBJECTIVES: We evaluated the feasibility of using chemical shift gradient-echo (GE) in- and opposed-phase (IOP) imaging to grade glioma.

    METHODS: A phantom study was performed to investigate the correlation of (1)H MRS-visible lipids with the signal loss ratio (SLR) obtained using IOP imaging. A cross-sectional study approved by the institutional review board was carried out in 22 patients with different glioma grades. The patients underwent scanning using IOP imaging and single-voxel spectroscopy (SVS) using 3T MRI. The brain spectra acquisitions from solid and cystic components were obtained and correlated with the SLR for different grades.

    RESULTS: The phantom study showed a positive linear correlation between lipid quantification at 0.9 parts per million (ppm) and 1.3 ppm with SLR (r = 0.79-0.99, p
