This study set out to discover the nature of the interactions that occur between the radiographer, patient and high technology imaging equipment. The investigation focussed upon two radiology departments where patients had just had either a CT or MR scan. No attempt was made to generalise the findings, since it was the existence of the phenomena, rather than the frequency of events elsewhere, that was under scrutiny. A thorough literature review revealed a distinct lack of previous research in this area, with only quantitative methodological approaches having been employed. This study was a purely inductive qualitative investigation, that sought to explore feelings, meanings and roles within the context of the imaging departments. A thematic content analysis of 49 semi-structured patient interviews revealed a varying degree of satisfaction, fear and misunderstanding. These data were complemented with 8 interviews of self-selecting radiographers, who had experienced a CT or MR scan, and 8 interviews of radiographers who predominately worked in these high technology areas. Following data analysis, specific typologies were derived from the concepts to formulate a model of the humanistic interaction with medical imaging technology. Discussion of the findings related to the technological and humanistic literature, and the alternative micro-sociological perspectives of Symbolic Interactionism and Critical Dramaturgy, gave a more creative explanation of the unique theory. The final section of the discussion considered the potential for future research and a reflexive analysis of the study. In conclusion, the model is considered to be a valid conceptual representation of the interactions within the context of the naturalistic setting. The theory developed provides enlightening insights with respect to roles and rituals performed in the radiology department.

A method is reported for the bilateral, synchronous distribution of injected drugs to both sides of the brain simultaneously. Arguments have been made for the advantages of this approach over unilateral intracarotid injections for studying the direct effect of drugs on central synaptic sites. Using this method, preliminary studies have been made of the effects of both adrenergic and cholinergic drugs on the activation of the electroencephalogram in both unanesthetized curarized cats and in cats subjected to mid-brain reticular coagulation. These studies indicate the possible co-existence of both adrenergic and cholinergic components in the mid-brain reticular formation and suggests that anatomically these sites probably are not identical. / Medicine, Faculty of / Anesthesiology, Pharmacology and Therapeutics, Department of / Graduate

Introduction Forensic radiography is both a vital tool and a subspecialty in forensic medicine. It can be used to complement autopsy findings and reveal minor injuries overlooked during autopsy. It is also an important tool used in the identification of the dead and for establishing abuse in the living. In the United States of America, one million abuse cases are resolved annually using medical imaging. The Nigerian National Bureau of Statistics has reported a high crime rate in Lagos State and forensic radiography could be used to resolve non-accidental injury and other criminal cases. Aim of the study The aim of this study was to explore and describe the experiences, attitudes and knowledge of radiographers and forensic pathologists regarding forensic radiography services rendered in Lagos state, Nigeria. The study aimed to identify the reasons that led to radiographers being reluctant to perform forensic radiographic examinations. Methodology A qualitative, exploratory, and descriptive study design was used to explore the experiences, attitudes and knowledge of radiographers and forensic pathologists regarding forensic radiography services. The population and sampling were determined by the numbers of radiographers and forensic pathologists employed in two government-owned tertiary institutions in Lagos state. The researcher used purposive sampling to gain a deeper understanding of the real-life experiences of the participants regarding forensic radiography services in Lagos. Focus group interviews were conducted with radiographers and forensic pathologists who work in the two government-owned tertiary teaching hospitals. Participation was voluntary and consent forms were signed by all participants before the commencement of the study. The interviews were audio-recorded and later transcribed verbatim. Thematic analysis was used for the identification of codes and categories. Results The following themes emerged: good and bad experiences of forensic radiographers, varying inadequate knowledge of forensic radiography, different attitudes towards forensic radiography, description of radiographers’ roles on forensic medicine teams, and recommendations for improvements of forensic radiography in Lagos state. Discussion The findings showed that in Lagos, forensic radiography was underutilized to resolve civil and criminal cases, and that there is need to improve the quality of forensic radiography services in Lagos state. Radiographers need to show more commitment in the aspect of postmortem imaging Conclusion It was concluded that the government should provide equipment and infrastructure for forensic radiography in Nigeria, specifically in Lagos state. Further research needs to be done to develop a curriculum in forensic radiography. Nigerian universities should introduce forensic radiography courses at undergraduate level and specialist training at postgraduate level. / Dissertation (M.Rad)--University of Pretoria, 2020. / NILL / Radiography / M.Rad / Unrestricted
