These studies have highlighted that techno-scientific developments are path-dependent; that is embedded within particular historical and socio-economic and technical enfoldings. They have consistently shown that the concrete environment in which techno-scientific research is conducted gets embodied in the design and Abstract In the last 30 years, Science and Technology Studies (STS) have deconstructed the foundation of diffusion models of science, by showing that science and society are inextricably linked. Nevertheless, STS has rarely ventured into cross-cultural trans-national analyses of techno-scientific research. In recent times postcolonial science studies has attempted to shift the STS to trans-national domain, particularly in relation to impact of colonialism. This paper is in line with these efforts at analyzing techno-scientific research. I have analyzed Magnetic Resonance Imaging (MRI) research and development in the United States, India, and the United Kingdom in order to put into broad relief the hierarchical global topography of techno-science. I have shown how colonialism continues to undergird analyses of techno-scientific research. I have argued that in the first instance we need a ‘decolonization of imagination’ if we need to move beyond dualist categories of west/non-west, developed/developing, north/south, and so on, which are parasitic to some conception of ‘lack’ of the non-west.

Nevertheless, until recently, STS, with the exception of Sharon Traweek’s (1988) study, comparing the culture of high-energy physicists in Japan and the US, and Karin Knorr Cetina’s (1999) comparative study of the European Laboratory for Particle Physics in Switzerland and a molecular biol- ogy laboratory in Germany, rarely ventured into cross- cultural or trans-national analysis of technoscientific practices. 2 To a significant extent this has been a result of micro-level focus of STS. However, it often has had an inadvertent consequence – when some STS scholars extended their work to trans-national or global context Amit Prasad University of Missouri-Columbia, USA prasada@missouri.edu
