Nuclear Medicine Safe During Pregnancy: Guidelines and Precautions
During the procedure, staff members wear protective shielding and monitor radiation levels to protect themselves. Radiation Dose Comparison The amount of radiation from a nuclear medicine procedure is generally comparable to, or sometimes lower than, a standard diagnostic CT scan.
After the scan, patients are given specific instructions regarding hydration and, if necessary, limiting close contact with pregnant individuals or young children for a short period. While the radiation dose to the fetus is often very low, particularly with bone scans or lung ventilation studies, the medical team will evaluate the risk versus benefit on a case-by-case basis.
