In paediatric nuclear medicine the majority of the scans require intravenous (IV) access to deliver the radiotracers. Children and parents often cite procedural pain as the most distressing part of their child’s hospitalization. In our department, various pain management strategies including physical and psychological distraction methods and pharmacological intervention have been implemented for the reduction of procedural pain. The purpose of this study was to evaluate and compare different pain reduction strategies used in the paediatric Nuclear Medicine department. Read More

Whole-body (WB) magnetic resonance (MR) imaging in children is of special interest because it is radiation free and can be used to evaluate systemic conditions, exploiting the advantage of the superior soft-tissue contrast provided by MR imaging. An important clinical application of whole-body MR imaging in children is its use for screening of oncologic conditions, tumor characterization, and staging. However, the list of non-oncologic applications of WB MRI has recently expanded to include the evaluation of numerous multisystemic conditions. This is a pictorial review of different oncologic applications of WB MRI including cancer predisposition syndromes, solid neoplasias and lymphomas, as well as of non-oncologic applications of WB MRI including chronic recurrent osteomyelitis (CRMO), enthesitis related arthritis (ERA), vascular malformations and benign tumors. In this review we discuss the advantages and challenges of conventional and functional MRI sequences including the use of diffusion weighted imaging (DWI), color-encoded DWI enhanced with iron supplement Ferumoxytol as blood pool contrast agent, as well as the advantages and disadvantages of the recently introduced WB positron emission tomography (PET)/MRI.

Thyroid cancer is the most prevalent endocrine malignancy in the pediatric population. Accurate diagnosis and staging of thyroid carcinoma demand a multimodality approach, including anatomic imaging with US, CT, and MRI, alongside functional or metabolic nuclear imaging. Novel imaging techniques such as US elastography, contrast-enhanced US (CEUS), superb microvascular imaging (SMI) and dual-source dual-energy thyroid CT have offered non-invasive tools to assess disease status. Furthermore, the emerging field of radiomics/radiogenomics and artificial intelligence is continuously growing, creating models to classify or predict disease behaviour. We provide a comprehensive overview of the essential imaging characteristics of pediatric thyroid carcinoma using conventional and novel imaging techniques. In addition, we illustrate the multimodality, multidisciplinary, and collaborative approach across pediatric radiology and nuclear medicine in pre-operative, post-operative and post-treatment imaging surveillance of cancer thyroid in children.
