In the Multi-photon gamma-ray coincidence imaging method, theranositics, which combines imaging and nuclear medicine, is regarded as one of the important medical applications. At present, several beta- and alpha-emitting nuclides are being used clinically for nuclear medicine treatment.
In this study, we examined the basic data on how far pharmacokinetic information can be collected using the existing gamma camera for ²²³Ra, an alpha-emitting nuclide that continuously undergoes multi-stage decay.
