A trial looking at a scan using iodine 124 to see areas of neuroblastoma

This trial compared iodine 124 PET-CT scans with the iodine 123 scans which were routinely used at the time. Researchers used the scans to look at whether neuroblastoma had come back after treatment or spread to another part of the body

The trial was supported by Cancer Research UK. It was open for people to join between 2014 and 2019. The team reported the results in 2021.
