Explaining the adoption and use of computed tomography and magnetic resonance image technologies in public hospitals.

CT and MRI adoption by public hospitals is mainly determined by hospital inputs and outputs. However, the use of both medical technologies is mainly influenced by conventional radiology studies and CT adoption. These results suggest that both choices - adoption and use of advanced medical technology - may be separate decisions as they are taken possibly by different people (the former by managers and policymakers and the latter by physicians).
