Observational StudyInvisible cortex sign: A highly accurate feature to localize the inferolateral central sulcus.
The central sulcus is a key landmark on MRI of the brain, but its inferolateral portion is difficult to identify if unable to trace the sulcus superoinferiorly. The authors observed that the cortex abutting the central sulcus appears isointense to the adjacent white matter on DWI, we named this the 'invisible cortex sign' and our study evaluates whether it could be used to identify the inferolateral central sulcus. ⋯ The 'invisible cortex sign' is a highly accurate method of identifying the inferolateral central sulcus on a single axial DWI slice without relying on the more superior aspects of the sulcus.

Since the introduction of a shared e-scooter service to Auckland in October there have been multiple media reports of associated injuries, but no quantitation of the number or severity of these injuries, or the impact on hospital emergency department services in Auckland. ⋯ Introduction of shared e-scooters has resulted in a large number of serious related injuries that have required urgent radiology imaging. Many of these patients required further specialist consultation or surgery, and place an increased burden on overstretched emergency department services.

Multicenter StudyDiagnostic reference levels for 18 F-FDG whole body PET/CT procedures: Results from a survey of 12 centres in Australia and New Zealand.
The aim of this work is to report diagnostic reference levels (DRLs) for hybrid positron emission tomography and x-ray computed tomography (PET/CT) exams in Australia (AU) for Queensland (QLD) and Western Australia (WA) (AU QLD/WA) and New Zealand (NZ). ⋯ The current DRLs were proposed for AU QLD/WA and NZ for 18 F-FDG whole-body PET/CT examinations. Variations existed in the current practice of AU QLD/WA and NZ PET/CT examinations. There is a need to optimize the radiation doses delivered from PET/CT examinations.

Contouring experiences amongst Australian, New Zealand and Singaporean radiation oncology trainees. Is it enough? What next?
This paper reports the key findings of the first survey of Australian, New Zealand (ANZ) and Singaporean radiation oncology trainees on contouring and planning. ⋯ This initial detailed survey of ANZ and Singaporean trainees on contouring and planning indicates that dedicated protected time without interruption is required for this integral activity with current hours spent on this activity inadequate. Optimisation and improvement in a number of areas is required. Feedback from this study should be adopted by sites and networks. Feedback could also be considered as the Faculty of Radiation Oncology transitions into programmatic assessment.

A Morel-Lavallée lesion is a post-traumatic soft tissue degloving injury which presents as a haemolymphatic mass or collection. Morel-Lavallée lesions are the result of direct trauma or shearing forces abruptly separating skin and subcutaneous tissue from underlying fascia causing disruption of perforating vessels and nerves, creating a potential space that may fill with blood, lymph and debris forming a collection. ⋯ Early diagnosis and management is essential to prevent complications. We present this pictorial review to highlight the imaging characteristics of Morel-Lavallée lesions across imaging modalities to improve recognition, early diagnosis and management.
