Introduction: Individuals with head and neck cancer (HNCa) face myriad biopsychosocial challenges. Even after treatment completion, these challenges may continue to cause diminished quality of life (QoL). Resilience may serve to minimize the impact of HNCa and, thus, maximize QoL. The purpose of this study was to identify resilience in HNCa survivors and explore its potential relationship with QoL.
Methods: Thirty-one HNCa survivors completed three validated, self-report questionnaires pertaining to the collection of resilience and QoL data. Descriptive, correlational, and observational analyses were performed.
Results: Resilience was identified in the HNCa survivors and a positive correlation was found between resilience …

The hybridization of magnetic resonance imaging (MRI) and positron emission tomography (PET) provides the benefit of soft-tissue contrast and specific molecular information in a simultaneous acquisition. The applications of PET-MRI in radiotherapy are only starting to be realised. However, quantitative accuracy of PET relies on accurate attenuation correction (AC) of, not only the patient anatomy but also MRI hardware and current methods, which are prone to artefacts caused by dense materials. Quantitative accuracy of PET also relies on full characterization of patient motion during the scan. The simultaneity of PET-MRI makes it especially suited for motion correction. However, quality assurance …
