Moderators: Katya Rozovsky & Pascale Grimard

The session will focus on imaging diagnosis and management of common pediatric neoplasms. It will provide updates on imaging diagnosis of pediatric lymphoma, evaluation of therapeutic response, and post-treatment surveillance. It will address the sonographic features of pediatric thyroid carcinoma which can help in guiding a management approach. It will describe current imaging protocols and advanced imaging techniques for pediatric brain tumors and provide key MRI features of common tumor types. It will outline imaging features of neuroblastomas across different modalities, describe image-defined risk factors and help to assess tumor resectability.

At the end of this session, delegates will be able to:

• Describe the contributions of imaging to the diagnosis, therapeutic response assessment, and post-treatment surveillance of pediatric lymphoma, including the spectrum of imaging manifestations and key pediatric-specific clinical and technical considerations.
• Apply a practical sonographic approach to pediatric thyroid carcinoma to support evidence-informed decisions regarding biopsy versus follow-up of thyroid nodules in children.
• Analyze current imaging protocols, key MRI features of common pediatric brain tumors, and recent advances in neuroimaging to enhance diagnostic accuracy and support treatment planning.
• Evaluate the multimodality imaging features of neuroblastoma and apply image-defined risk factors to determine pre-treatment risk group and surgical resectability.

Pediatric Thyroid Cancer
Claudia Martinez Rios-Arellano

This presentation will address the sonographic features of pediatric thyroid carcinoma and the challenges of reporting thyroid ultrasound. Awareness of the distinct imaging features of thyroid carcinoma can help in the management approach, deciding when it is best to biopsy or when to follow-up.

Pediatric Brain Tumors - Imaging Protocols and Updates
Tahani Ahmad

This presentation reviews current MRI protocols and imaging techniques in pediatric brain tumor evaluation. Emphasis will be placed on protocol optimization, advanced imaging sequences, and their role in tumor characterization, surgical planning, and post-therapy assessment. This includes MRS, perfusion, DTI, and fMRI.

Neuroblastoma Updates
Ramy El-Jalbout

This presentation will review the typical and varied imaging features of neuroblastomas across multiple modalities and demonstrate how image-defined risk factors are applied to determine pre-treatment risk groups and assess tumor resectability.
