When you add an anatomic entity or imaging observation component to your template, you may add one or more characteristics to it. When you import a template into an imaging application, each template component becomes a heading and characteristics describe the component. For example, the component could be "Lesion" with the characteristics of "Enhancement Quality", "Proportion Enhancing", "Proportion nCET", and "Proportion Necrosis".
Anatomic entity characteristics and imaging observation characteristics can be quantifiable or non-quantifiable. A quantifiable value can be scale, quantile (such as quartile, percentile, or n-tile), numerical like a decimal number in a UCUM (Unified Code for Units of Measurement) unit, and interval. Examples of non-quantifiable characteristics are present, absent, and not applicable.
