Treatment with ionising radiation is a valuable component of treatment schedules for a many children and young people with cancer. While some form of radiotherapy has been in use for over 100 years, a series of innovations has revolutionised paediatric radiation oncology. Mostly, high-energy X-ray photons are used, but proton beam radiotherapy is increasingly offered, especially in children and young people. This is to reduce the radiation exposure of healthy normal tissues and so the likelihood of adverse effects. Other methods of radiotherapy delivery include brachytherapy and molecular radiotherapy. The most appropriate treatment technique should be selected for every child. Advances in computers and imaging, developments in the technology of radiation delivery and a better understanding of pathology and molecular biology of cancer, coupled with parallel improvements in surgery and systemic therapy, have led to a transformation of practice in recent decades. Initially an empirical art form, radiotherapy for children has become a technically advanced, evidence-based cornerstone of increasingly personalised cancer medicine with solid scientific foundations. Late sequelae of treatment—the adverse effects once accepted as the cost of cure—have been significantly reduced in parallel with increased survival rates. The delivery of radiotherapy to children and young people requires a specialised multiprofessional team including radiation oncologists, therapeutic radiographers, play specialists and physicists among others. This article reviews the types of radiotherapy now available and outlines the pathway of the child through treatment. It aims to demonstrate to paediatricians how contemporary paediatric radiation oncology differs from past practice.

“…With regard to MR imaging, knowledge of the acquisition, processing and interpretation of MR images and the respective sequences is a prerequisite for oMRgRT [20][21][22]. As the national professional education for RTT, physicists and radiation oncologists varies greatly from country to country, it is difficult to define and provide an obligatory core set of minimum requirements.…”

“…Gradient non-linearity can cause geometric distortions predominantly at the periphery of the imaging field which may require correction. 8 The MRI to CT registration process can also result in an expected 2 mm registration error. 9 Such errors may be exacerbated by differences in sequences used (particularly in the diagnostic MRI setting), patient susceptibility and differences in set-up due to the inability to use radiotherapy immobilisation devices or incompatibility of site-specific receiver coils, use of a concave MRI bed, and/or bore size limitations.…”

Rates of MRI simulator utilisation in a tertiary cancer therapy centre

Summary Magnetic resonance imaging (MRI) is increasingly being integrated into the radiation oncology workflow, due to its improved soft tissue contrast without additional exposure to ionising radiation. A review of MRI utilisation according to evidence based departmental guidelines was performed. Guideline utilisation rates were calculated to be 50% (true utilisation rate was 46%) of all new cancer patients treated with adjuvant or curative intent, excluding simple skin and breast cancer patients. Guideline utilisation rates were highest in the lower gastrointestinal and gynaecological subsites, with the lowest being in the upper gastrointestinal and thorax subsites. Head and neck (38% vs 45%) and CNS (46% vs 67%) cancers had the largest discrepancy between true and guideline utilisation rates due to unnamed reasons and non‐contemporaneous diagnostic imaging respectively. This report outlines approximate MRI utilisation rates in a tertiary radiation oncology service and may help guide planning for future departments contemplating installation of an MRI simulator.
