This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

Primary objective

To assess the extent to which presentation to the individual of images of their own body created during medical imaging procedures increases or decreases health behaviours such as:

1. dietary fat intake;

2. physical activity levels;

3. smoking;

4. alcohol use;

5. damaging exposure to sunlight or other sources of ultraviolet radiation.

This will be considered in comparison to the impact of communicating the same findings in a way which does not involve showing the person the source images derived from the imaging procedure (such as solely through oral feedback, or a written report).

Secondary objective

A secondary objective is to determine the impact of this feedback on consumers':

1. understanding of the relevant condition and of the risk information they have been given;

2. perceived severity and risk of disease;

3. perceived control over the disease risk;

4. perceived effectiveness of the risk‐reducing behaviour;

5. emotional response, including general anxiety and condition‐specific worry.
