MRI and the Surgical Treatment of Low Grade Gliomas
- 38 Downloads
The advent of CT Scan has revolutionized the diagnosis of gliomas, particularly those of low grade. The discovery of such lesions at very early stages, before the appearance of clinical deficits or of radiological signs of compression, has thus allowed surgical treatment that could hopefully be curative in certain cases. However, CT Scan images of ≪ benign ≫ gliomas are often caracterized by a poorly limited hypodensity, making the presurgical evaluation of the limits of the area to be removed very delicate. Furthermore, during the operation itself, we are often made aware of the difficulty in distinguishing the boundaries of these tumors imbedded in the white matter.
