Intracranial gliomas: MRI study

ABSTRACT

Gliomas represent one-third to 45% of all intracranial tumours. MRI has improved the detection and localization of intrinsic primary glial tumours, but has not yet been proven to add specificity beyond what can be obtained with Ct. The signal abnormalities produced by glial neoplasms can be devided into five types intrinsic neoplasm; neoplasm-associated cysts; necrotic neoplasm; neoplasm-induced neovascularity with BBB breakdown and contrast enhancement; and neoplasm-produced edema. This study highlights some of the features of the intracranial gliomas on MR scanning
