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.
