Behind the hedges: how to convey uncertainty in imaging reports

The imaging report is a summary document of findings and the primary form of communication of such to referring clinicians. Expressing uncertainty in the summary report is clearly difficult and the literature is unanimous that there is no agreement between imaging consultants and clinicians, and even between imaging consultants themselves, as to the meaning of uncertainty phrases. It is important for the imaging consultants to express uncertainty in the imaging report, but it is equally important that the referring clinician understands the degree of that uncertainty. Individual terminology does not bridge that gap. The present study reviews the literature in order to differentiate between uncertainty phrasing and hedging, and to find best practice examples to inform practice. We suggest three approaches that may be applied.
