Pregnant patientsThe National Council of Radiation Protection and Measurements (NCRP) 1977 states ??. if in the best judgment of the attending physician, a diagnostic examination or nuclear medicine procedure at that time is deemed advisable to the medical well being of the patient, it should be carried out without delay, with special efforts being made, to minimize the dose received by the lower abdomen (uterus).?
The NCRP has set a suggested safe limit for the fetus at 50mGy
