    Radiological assessment of age-related changes of the microarchitecture of the bony trabeculae of the femoral neck and its clinical implication
    (2023-12) Aziz, Joseph; Yang, Lee; Wu, Lian; Asham, H.; Unitec, Te Pūkenga; University of Manitoba
    The bony trabeculae in the femoral neck are a crucial component of the hip joint's skeletal architecture. The primary aim of this study is to radiographically analyse anatomical geography of the trabecular pattern in the upper end of the femur of 158 women in two different age groups and to relay their pattern to the bone density. We aim to establish a robust foundation for utilizing trabecular pattern changes as diagnostic indicators for bony weakness severity.

    A journey on an unknown path : the unexpected experience of online simulation-based teaching to medical imaging students under COVID-19 lockdown
    (2020-06-24) Aziz, Joseph; Vyas, Madhusudan; Thorogood, Joanna; Unitec Institute of Technology
    The Covid-19 pandemic has driven rapid changes to higher education across the globe, in terms of mode of delivery and assessment. Online teaching has previously been considered as an alternative or supplementary pedagogy to face to face teaching, with differing levels of success. Particularly within allied health programmes and the unique challenges they present, such as the need to deliver theoretical content which underpins and supports clinical practice. We utilised various online simulation-based resources, e.g. Mannequins, PACS simulator, Sectional-anatomyTM in our approach. This unanticipated encounter provided upskilling opportunities and allowed us to provide an effective alternative to face to face delivery.

    The effectiveness of concomitant use of cross-sectional anatomy and CT images in teaching anatomy to medical imaging students
    (2019-12-05) Aziz, Joseph; Thorogood, Joanna; Unitec Institute of Technology
    BACKGROUND: Cross-sectional anatomy is crucial in the comprehensive study of the details of the whole body to the medical students in general; while to the medical imaging students in particular. Furthermore, it is most important to the medical imaging specialists during their education or after graduation to improve their skills in imaging interpretation; mainly for CT scan and MRI. OBJECTIVE: To determine the value of teaching cross-sectional anatomy to medical imaging students and its effectiveness to improve their skills in imaging interpretation. MATERIALS AND METHODS: Fifty-eight students from the medical imaging program were were included in this study. Students were divided into two groups; Group I (29) from the academic year 2017-2018 had been taught sectional anatomy without concomitant use of CT images 1 year before the test, Group II (29 ) from the academic year 2018-2019 and were studying sectional anatomy with concomitant use of CT images. The educational methodology consists of identifying anatomical structures displayed in plastinated sections from human cadavers available on online resource and its corresponding anatomical structures in computed tomography (CT) sections from healthy patients on the same or another online resource. To assess and verify the impact of learning sectional anatomy on radiological knowledge, students were asked to identify ten anatomical structures on thoracic CT images at the level of the aortic arch (superior mediastinum). RESULTS: The percentages of students in groups I and II who correctly identified the anatomical structures in the test were measured. The percentage of errors in group II were much lower than the errors in the group I. Analysis of the results revealed a significant difference in test scores with scores of 89.7% and 65.5%, respectively. CONCLUSION: These results provide evidence that the implementation of the sectional anatomy as a tool in teaching anatomy becomes a crucial fact in medical imaging curricula and has a great impact on subsequent CT interpretation.
