In health care; there is a need for patient adaption of clinica ltext; so that patients can understand their own health records. As a base for construction of automated texts implification tools; characterization of the clinical language is needed.

We describe a corpus of 0.43 mill. radiology reports from a University Hospital; characterize it quantitatively and perform a qualitative content analysis. The results show thata limited set of words and phrases are recurrent in the reports and can be used for exchange to more easy-to-read vocabulary. Semantic categories such as body parts; findings; procedures; and administrative information can be used in the simplification process.

This study investigates the potentials and the pitfalls for texts implification of medical Swedish into general Swedish for laymen.
