¹ For ex­pos­ures in the me­di­um-dose or high-dose range and for thera­peut­ic ex­pos­ures in fe­male pa­tients, the phys­i­cian per­form­ing the pro­ced­ure must es­tab­lish wheth­er the pa­tient is preg­nant.

² If preg­nancy is de­term­ined or can­not be ruled out, this must be weighed against the need for the ex­pos­ure in the jus­ti­fic­a­tion. In the op­tim­isa­tion, both the dose to the un­born child and that to the moth­er must be taken in­to ac­count.

³ If the uter­us of a preg­nant pa­tient lies with­in the area ex­amined, the dose to the uter­us must be doc­u­mented.

⁴ In the case of nuc­le­ar medi­cine ex­pos­ures, breast­feed­ing pa­tients must be in­formed about the need for and dur­a­tion of a sus­pen­sion of breast­feed­ing on ac­count of the con­tam­in­a­tion of breast milk.
