Streamlining Paediatric Palliative Radiotherapy: A Case Study on Reducing Procedural Burden and Avoiding General Anaesthesia Using a Simulation‐Free Radiotherapy (SF‐RT) Protocol

Journal of Medical Radiation Sciences, EarlyView.
This paper presents two cases of young children who were treated with simulation‐free radiotherapy. We demonstrate that this workflow is feasible in children requiring palliative radiotherapy with the potential to expedite treatment, reduce procedural burden on the child and their family, and eliminate a general anaesthetic procedure.

Gradual Colonic Impaction of a Chicken Bone Associated with Inflammatory Pseudotumor Formation and Nonocclusive Colon Ischemia

Case Reports in Radiology, 2014
Foreign body (FB) ingestion is a common clinical problem and most FBs pass through the gastrointestinal tract without the need for intervention. A wide spectrum of clinical presentations may be possible and these can be either acute or chronic.

Congenital kidney malformation: Computed tomography and scintigraphy findings of renal reversed rotation

Radiology Case Reports, 2019
Renal reversed rotation is a congenital abnormality due to anomalous kidney rotation around its long axis, resulting in faced laterally renal hilum; this condition is associated with several vascular variants.

Feasibility of a simultaneously integrated boost concept for hypofractionated stereotactic radiotherapy of unresected brain metastases

Radiation Oncology, 2023
Background In stereotactic radiotherapy, dose is prescribed to an isodose surrounding the planning target volume (PTV). However, the desired dose inhomogeneity inside the PTV leaves the specific dose distribution to the gross tumor volume (GTV ...

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Beyond geometrical overlap: a Dosimetrical Evaluation of automated volumes Adaptation (DEA) in head and neck replanning

Technical Innovations & Patient Support in Radiation Oncology, 2017
Introduction: Automated target volumes adaptation could be useful in H&N replanning, but its dosimetric impact has not been analyzed. Primary aim of this investigation is dose coverage assessment in fully automated and edited PTV adaptation settings ...

The scenario-based generalization of radiation therapy margins

, 2015
We give a scenario-based treatment plan optimization formulation that is equivalent to planning with geometric margins if the scenario doses are calculated using the static dose cloud approximation.

Improving plan quality and consistency by standardization of dose constraints in prostate cancer patients treated with CyberKnife. [PDF]

, 2013
Treatment plans for prostate cancer patients undergoing stereotactic body radiation therapy (SBRT) are often challenging due to the proximity of organs at risk.
