Outcome Measures

Primary Outcomes (1)

  • scores obtained in FactCOG as a whole and in each subscale

    Primary analysis will be performed on all patients included in the study, including history of Ewing (treated without HDMTX) and osteosarcoma (treated with HDMTX). This population is the main analysis population of the study.

Interventions

MRIPROCEDURE

This assessment will be planned in the year after the consent signAll patients will have one brain MRI performed in Henri Mondor Hospital on a 3T MR unit (Skyra, Siemens, Erlangen). The procedure will include: 1. a 3D-FLAIR imaging 2. a morphometric study based on a 3DT1 MPRAGE gradient echo sequence (TR / TI / TE = 2300/900 /2.9 ms) 3. an analysis of the anatomic connectivity of the patient's brain assessed using a 1.5mm isotopic DTI with a high number of directions (HARDI / 65 directions / b=1500s/mm2). 4. An evaluation of neuronal dysfunction using MR Spectroscopy. Spectroscopic data will be collected using a 2D CSI laser with a short TE technique. 5. Magnetization transfer imaging providing information about integrity of membranes.
