Revising the FDOPA PET imaging leaflet

Gill and Giovanna met online on Tuesday 18th January, to discuss some feedback that Giovanna had received from one of her colleagues. Looking at the version of the leaflet created on 3rd December 2021, it was suggested that rather than have two images of the PET scan (one from the side and one from the top), there should be one image that included a representation of a human head or face, to provide the scan with some anatomical context.

In response to this, Gill created a range of images that showed a human head, either in profile or face-on, with a suitable FDOPA PET scan incorporated into the image. This meant drawing a scan with a front-on view of the brain, that matched with the top and side view scans that Gill had already draw. The images that Gill created are shown below, and three of these were added to test versions of the leaflet and sent to Giovanna for her feedback.

Gill and Giovanna met online again on Tuesday 25th January 2022 to decide on which , if any, of these images to use in the leaflet. Giovanna had also discussed the leaflet with Mattia and they agreed that the profile view, with the solid grey head silhouette, was the image they would like to use. The grey colour was taken from the King’s colour palette and matched the grey used in other images in the leaflet. Mattia had also suggested that Gill include an image of a doctor talking with a patient, to go alongside the second paragraph of text in the leaflet. Gill had created an image for the Patient Information Sheet project that could be used for this purpose, without requiring any additional editing. The revised dynamic FDOPA PET imaging leaflet, containing the new images, is shown below:

At this stage, only the leaflet relating to dynamic FDOPA PET scanning had been created, with the intention of creating a companion leaflet that would cover static FDOPA PET scanning. This required some changes to the text as, after waiting one hour for the tablets to take effect, the patient has an additional one hour wait after being injected with the radioactive tracer, before they enter the scanner. In a dynamic scan, by contrast, the patient is inside the scanner when the tracer is injected, and the scanning starts immediately after the injection. Therefore, as well as revising the text, Gill would need to add some visual indication of this additional hour of waiting, on top of the hour’s wait after taking the tablets.

As space is tight in the leaflet, Gill didn’t think it would be possible to add another image to represent the injection of the radioactive tracer. She instead decided to replicate the image of the clock, indicating the passing of one hour. Removing the image of the tablets provided room for the additional clock and Gill used text labels above the clocks to indicate to what they were referring. The revised static FDOPA PET imaging leaflet is shown below:

Gill had some concerns that the image of the two clocks in the static imaging leaflet may not be sufficiently intuitive. She sent both dynamic and static imaging versions of the leaflet to Giovanna, suggesting that she test the static imaging leaflet out on her colleagues to see what they thought. Giovanna liked the use of the two clocks but agreed that she would need to test the leaflet to see if it was obvious to a viewer what was being depicted. Giovanna also said that it would be good to revise the titles of both leaflets, to indicate that one was referring to dynamic imaging and the other to static imaging, but that could be done once the remainder of the leaflet had been approved.
