Tumeurs cranioencéphaliques. Techniques d’imagerie et sémiologie

Imaging has a significant role in the diagnosis and more particularly in the evaluation of the therapeutic possibilities and prognosis of cranio-encephalic tumours (CET). After surgery, it is used at the same time to evaluate the tumour resection and to consider the associated treatments. In the follow-up, imaging allows to appreciate the answers and the complications of these therapies. MRI is currently unanimously recognized as the examination of choice for the diagnosis and the follow-up of CET. The diffusion and perfusion MRI techniques, available on the modern imagers are easily realizable in clinical practice. They bring further information basically different from those provided by morphological imaging, particularly interesting for the diagnosis but also during the follow-up of these lesions.
