Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.

However, in order to avoid an invasive surgical procedure to remove the lesion, a certain diagnosis of its benignity is essential. The contribution of advanced techniques in MRI, such as spectroscopy in the characterization of these lesions, has not yet been studied today

cerebral MRI

Patients who agree to participate in the study will perform a 3T multi-parametric MRI with advanced spectroscopic imaging techniques and standard protocol.

A neurological consultation will take place during the inclusion visit as well as a questionnaire and a control MRI at 1 year and 2 years +/- 1 month.
