The role of the radiographer in promoting health: A qualitative examination of diagnostic radiographer perspectives at a Scottish Major Trauma hospital.

INTRODUCTION: Publication of Government directives and initiatives have signalled a shift in healthcare priorities, with growing emphasis on prevention and early intervention. In comparison to other allied health professions, perceptions of Diagnostic Radiographers of their contribution to addressing these initiatives and role in promoting health, has not been explored. There is limited evidence on current practices, knowledge and confidence in providing health promotion advice to patients within this professional group. This study aimed to investigate the perceptions of Diagnostic Radiographers of their role in promoting health. METHODS: Semi-structured focus groups were conducted with 20 Diagnostic Radiographers recruited via convenience sampling from a Scottish Major Trauma Hospital. Focus groups were transcribed and analysed using thematic analysis. RESULTS: Findings demonstrated a lack of awareness and understanding of government initiatives and professional body recommendations surrounding health promotion. Diagnostic radiographers felt ill-equipped to provide appropriate and impactful health promotion advice and reported lack of time as a barrier to contributing to such activities. CONCLUSION: Diagnostic Radiographers noted a willingness to undertake additional training to enable them to participate and were able to identify areas where they could adopt health promotion activities in their clinical practice. Addressing the barriers to participation is essential to empower Diagnostic Radiographers to contribute to the health promotion agenda. IMPLICATIONS FOR PRACTICE: There is a need to address profession specific education at pre-registration and post-qualification levels, to ensure Diagnostic Radiographers are equipped with the knowledge, skills and confidence to promote health to their patients. Strong leadership is essential for creating a positive environment to facilitate education, training and the acceptance of health promotion as a key part of a diagnostic radiographer's role.

Reading the mind in cartoons and stories: an fMRI study of 'theory of mind' in verbal and nonverbal tasks.

Previous functional imaging studies have explored the brain regions activated by tasks requiring 'theory of mind'--the attribution of mental states. Tasks used have been primarily verbal, and it has been unclear to what extent different results have reflected different tasks, scanning techniques, or genuinely distinct regions of activation. Here we report results from a functional magnetic resonance imaging study (fMRI) involving two rather different tasks both designed to tap theory of mind. Brain activation during the theory of mind condition of a story task and a cartoon task showed considerable overlap, specifically in the medial prefrontal cortex (paracingulate cortex). These results are discussed in relation to the cognitive mechanisms underpinning our everyday ability to 'mind-read'.

A reproducible repositioning method for serial magnetic resonance imaging studies of the brain in treatment trials for multiple sclerosis.

Serial MRI is an important measure of disease progression in evaluating the treatment of multiple sclerosis (MS). Accurate comparisons of scans for lesion activity and lesion volume require precise repositioning of patients. A simple, reproducible repositioning method is described. In a multicenter treatment trial of MS using beta-interferon-1b, this method has been successful, with only 1.1% of scans being rejected because of poor repositioning.

Clinical, CSF, and MRI findings in Devic's neuromyelitis optica.

OBJECTIVES: Since Devic's original description of neuromyelitis optica in 1894 there has been much debate regarding its aetiology. A specific cause has been identified in a minority of cases but in most the question has arisen whether or not Devic's neuromyelitis optica is a variant of multiple sclerosis. This study was undertaken to help clarify this issue. METHODS: Neuromyelitis optica was defined as (1) a severe transverse myelitis; (2) an acute unilateral or bilateral optic neuropathy; (3) no clinical involvement beyond the spinal cord or optic nerves, and (4) a monophasic or multiphasic illness. The clinical and autoantibody status was documented. Patients underwent CSF examination and MRI of brain and spinal cord. RESULTS: Twelve patients, with a mean age of presentation of 35.1 years, were seen. Eleven were women; vision was reduced to counting fingers or worse in 10 patients and seven became confined to a wheelchair. Examination of CSF showed local synthesis of oligoclonal bands in only two patients and a neutrophil pleocytosis in two. A possible aetiology was identified in five: a specific connective tissue disorder (two), pulmonary tuberculosis (one), and possible acute disseminated encephalomyelitis (two). Six had non-specific increases in various autoantibodies. Eleven patients underwent MRI of the brain and spinal cord. In 10 there were diffuse abnormalities involving cervical and thoracic cords with extensive swelling in the acute phase. Brain MRI was normal in five; in five there were multiple deep white matter lesions, and one patient had minor age related changes. CONCLUSION: It is proposed that Devic's neuromyelitis optica is a distinctive disorder with some clinical, CSF, and MRI features different from those found in classic multiple sclerosis. In most cases a specific aetiology is not identified, but an immunological mechanism of tissue damage seems likely.

Maturation of cortical control over superior colliculus cells in cat.

The specialized receptive field properties of superior colliculus cells are believed to be dependent upon cortical influences. Yet despite a corticotectal projection near the time of birth and adult-like cortical cells at the beginning of the second week of life, specialized properties do not appear in many superior colliculus cells until quite late in postnatal development. We now report that this apparent conflict is due to the protracted functional maturation of the corticotectal system.
