Computer modification of 200-mAs raw scan data to simulate 100- and 40-mAs noise levels produces reconstructed images indistinguishable from real 100- and 40-mAs scans. This technique provides realistic reduced-dose images without patient radiation exposure and with identical image registration and motion artifact.
As access to positron emission tomography/CT (PET-CT) has widened, this technology has been incorporated into many adult oncology patient pathways. Use of PET-CT in paediatric and adolescent patients has lagged behind. Reasons include relative rarity of paediatric cancers, lack of robust trial data and fears over long-term radiation effects.
Background
Perinatal and childhood postmortem imaging has been accepted as a noninvasive alternative or adjunct to autopsy. However, the variation in funding models from institution to institution is a major factor prohibiting uniform provision of this service.
Objective
To describe current funding models employed in European and non-European institutions offering paediatric postmortem imaging services and to discuss the perceived barriers to future postmortem imaging service provision.
Materials and methods
A web-based 16-question survey was distributed to members of the European Society of Paediatric Radiology (ESPR) and ESPR postmortem imaging task force over a 6-month period (March-August 2021). Survey questions related to the radiologic and autopsy services being offered and how each was funded within the respondent’s institute.
Results
Eighteen individual responses were received (13/18, 72.2% from Europe). Only one-third of the institutions (6/18, 33.3%) have fully funded postmortem imaging services, with the remainder receiving partial (6/18, 33.3%) or no funding (5/18, 27.8%). Funding (full or partial) was more commonly available for forensic work (13/18, 72%), particularly where this was nationally provided. Where funding was not provided, the imaging and reporting costs were absorbed by the institute.
Conclusion
Increased access is required for the expansion of postmortem imaging into routine clinical use. This can only be achieved with formal funding on a national level, potentially through health care commissioning and acknowledgement by health care policy makers and pathology services of the value the service provides following the death of a fetus or child. Funding should include the costs involved in training, equipment, reporting and image acquisition.

Musculoskeletal trauma in the paediatric population covers a wide range of injuries; although many overlap with their adult counterparts, others are exclusive to the immature skeletal system. Ultrasound is a versatile tool particularly suited to both the imaging of children and the dynamic assessment of musculoskeletal injuries. This pictorial review aims to discuss a range of injuries, focusing on those commonly encountered in children. We shall describe the muscle-tendon-bone complex and changes that occur with increasing skeletal maturity and how this affects the type of injury encountered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
