However, health care providers do not currently use these isotopes to image cancer because they are difficult to produce in the amounts and purities appropriate for human use. In particular, they must be made using special isotopically enriched calcium targets. These targets are rare, expensive, and difficult to use in an accelerator. A new study describes ways to make and irradiate accelerator targets for scandium. These targets produce enough radioactive scandium to perform more than a dozen diagnostic PET assessments of human patients.
