Overview

Pediatric oncology imaging balances diagnostic accuracy with minimizing radiation and sedation. Modalities include ultrasound MRI and low dose CT when necessary. Protocols are tailored to age tumor type and clinical needs.

Staging and Response

MRI and ultrasound are preferred for many pediatric tumors to reduce radiation exposure. PET CT is used selectively for metabolic assessment and staging. Standardized response criteria support treatment evaluation.

Sedation and Motion Management

Techniques to reduce sedation include faster sequences and child friendly environments. Immobilization and distraction techniques improve image quality. Multidisciplinary coordination reduces procedural risk.

Long Term Surveillance

Survivorship imaging monitors for recurrence late effects and secondary malignancies. Minimizing cumulative radiation exposure is a priority in follow up planning. Coordination with pediatric oncology ensures appropriate surveillance.

Imaging for Liver Transplant
