Médulloblastome versus épendymome : qu’apporte l’IRM multimodale

On the morphological level, ependymomas had an intra ventricular topography in 90.9% of cases compared to 62.1% for medulloblastomas with an extension in the foramen magnum of 81.8% and 10.3%, respectively.

Cerebral tumors: specific features in children.

Aspects of Computer-Aided Tomography Scan (Cat) in the Child Intracranial Tumors in Abidjan: Report of 30 Cases

Computer-aided tomography scan represents here the focus of intracranial tumors diagnosis in the child and must be carried out as a clinical suspicion to improve the diagnosis of these tumors.

Perfusion magnetic resonance imaging in pediatric brain tumors

The implementation of a dynamic T2* perfusion sequence provided reliable results using an objective whole-lesion ROI and a new permeability indicator could efficiently discriminate high-grade from low-grade lesions in the pediatric population.



Perfusion imaging in the pediatric patient.

Perfusion imaging has proved to be a robust and valuable tool to assess the hemodynamic component in childhood CNS disease related to neoplasms and complications from their therapy, cerebrovascular occlusive disease, childhood CNS arteriopathies and trauma.

Infratentorial pediatric brain tumors: the value of new imaging modalities.

Dysembryoplastic neuroepithelial tumors: proton MR spectroscopy, diffusion and perfusion characteristics

The MR spectrum showing a slight increase in mI/Cr ratio, and higher ADC and lower r CBV values than normal parenchyma help to differentiate DNTs from other cortical tumors, which had higher rCBV and lower ADC values than D NTs.

Dynamic magnetic resonance perfusion imaging of brain tumors.

The role of MR perfusion in differentiating treatment effects, such as radiation necrosis, from tumor recurrence, and its advantages over more conventional methods are discussed.

Proton magnetic resonance spectroscopy of pediatric brain tumors.

Proton magnetic resonance spectroscopy may prove useful in characterizing neoplastic tissue in conjunction with more conventional imaging modalities.
