*
Consult nuclear medicine physician before performing
diagnostic study so that radionuclide that has the shortest excretion
time in breast milk can be used. Before study, the mother should pump
her breast and store enough milk in the freezer for feeding the infant;
after study, the mother should pump her breast to maintain milk
production but discard all milk pumped for the required time that
radioactivity is present in milk. Milk samples can be screened by
radiology departments for radioactivity before resumption of nursing.
