Examples of potentially useless scans: (a) Movement artefact resulting in an unusable scan. (b) MR brain scan with incorrect resolution in the axial plane (A) due to wrong acquisition plane (B) being used, potentially causing incorrect assessment of pathological features. (c) MR brain scan with insufficient brain coverage, resulting in a large portion of the cerebellum missed. The last slice was captured inferiorly in the axial plane (A), with corresponding level on the sagittal reconstruction for reference (B). (d) Incomplete transfer of the entire image acquisition, preventing complete image reconstruction and any analysis. MR magnetic resonance
