The following information should not replace the assessment and advice you have been receiving from your physician (cancer specialist, obstetrician, or any other healthcare provider). It is offered for your information only. Consult your physician.
The maximum amount of radiation that is considered permissible for fetal exposure is 50 Milli Gray units. The fetal radiation dose following a single PET-scan is unlikely to be higher than this level. The location of the PET-scan as well as the frequency will influence the amount of fetal dose of radiation exposure, and it is important for the technician to calculate the amount of maternal and fetal dose prior to the procedure. For similar cases and concerns please refer to the following paper on radiation and pregnancy:
