About medical examination and treatment in Japan

The drug injected into the patient in PET-CT scan is radioactive. What is the degree of radiation exposure?

In PET-CT scan, positron nuclide labeled agent is introduced into the body by injection or inhalation and it causes radiation exposure, although it is slight.

The agent used for PET is ultra-short half-life (its life of radioactivity is very short = the half-life is about two hours), and the amount of it is also very small. The degree of radiation exposure is about half of it from barium study of the stomach. Moreover, the radiation exposure at the level is said to have almost no adverse effect on human body.

Women who are pregnant or breastfeeding should avoid PET-CT, however.
