Although the new imaging modalities in radiology frequently use the terms "image" and "information," their meaning for the radiologist can be radically different from that for other scientists. Phenomenology (and hermeneutics) as an applied philosophical method can offer a much-needed clarification of these terms by examining the professional context of their use. Each profession accepts a different type of evidence for its professional judgments, evidence that is largely dependent on its specialized instrumentation. The paper will give examples of reliance on evidential meaning and illustrate the hermeneutic process of reading signals for global interpretation. While different professions will utilize different signals for their interpretations, the selection process involved is far from arbitrary; in each case it is a valid method of integrating individual patterns of information into a coherent whole. Phenomenological procedures can provide assistance toward reducing misunderstanding and frustration arising from the differences between the clinical world perception of the radiologist, on the one hand, and the scientific one of the physicist, on the other.
