Brief Summary

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

3D modeling associated with the tracking of nerve fibers meets the needs of preoperative planning for tumors and cervico-facial congenital malformations. Indeed, these lesions are closely related to the cranial nerves and in particular nerve V (infratemporal fossa), nerve VII (temporal bone, parotido-masseter region), nerves IX, X, XI, XII and the chain cervical sympathetic (infratemporal and cervical regions). The development of a model of this region will therefore improve the surgical management of these children.

Detailed Description

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

Children aged 1 to 5 benefiting from a 3T magnetic resonance imaging (MRI) at the Necker Enfants-Malades hospital for their care, meeting the inclusion criteria and participating in the study, will benefit during their MRI from the care, a sequence "Research" tractography MRI lasting 10 minutes. This sequence is already validated and proposed for tractography but in specialties other than pediatric ENT.

Tractography techniques are mathematical algorithms based on the diffusion tensor (micro-movements of water molecules in tissues) to reconstruct the path of nerve fibers in each volume unit of the MRI image (voxel).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients

Children aged 1 to 5 benefiting from a 3T MRI at the Necker Enfants-Malades hospital as part of the initial assessment of a tumor or cervico-facial malformation and at the first postoperative follow-up MRI if indicated for the care during a period of 12 months.

Group Type EXPERIMENTAL

Tractography MRI

Intervention Type OTHER

Addition to the sequences usually done for the care of these patients (CubeT2, Diffusion, CubeT1, CubeT2 fiesta, ASL, T1 injected with gadolinium), of a so-called "research" tractography sequence benefiting from CE marking and not requiring specific injection.

Search sequence acquisition time: 10 minutes.

Control patients

Children aged 1 to 5 benefiting from a 3T MRI at the Necker Enfants-Malades hospital as part of the initial assessment of an ENT pathology other than that of the patient group.

Group Type EXPERIMENTAL
