one image to another: why and how to study the uses and practices
of medical imaging in Dakar
IRD, UR "socioanthropologie de la santé"
Taking as a pretext ethnographic research recently
conducted in Senegal on the utilisation of radiography in scanning
tuberculosis patients, the author sets out his reasons for studying
medical imaging on the basis of a general inquiry into the role
that visual media play in social change and the identify-related
dynamics at work in contemporaray African societies. The study's
first resuts show that health care providers frequently call
on radiography. They share with their patients the same belief
in the power of medical imaging to represent reality, whereas
this practice es considered of little utility or even harmful
by public health professionals involved in tuberculosis control
campaigns. The author takes a primary analysis of his data,
to discuss the well-foundedness of his initial approach. He
brings into evidence the similarities and differences which
exist between the visual technologies for medical use and thoses,
such as television or photography, which give rise to mass-consumption.
Key-words : image - radiography - risk - Senegal
