Captación de yodo radiactivo - Risks

Nombres alternativos

Examen de captación de yodo; RAIU

Cuáles son los riesgos:

La cantidad de radiactividad es muy pequeña y no se ha informado de efectos secundarios documentados. La cantidad de yodo utilizado es menor a la que se ingiere normalmente en la dieta. Sin embargo, como sucede con cualquier exposición a la radiación, este examen no se recomienda para las mujeres embarazadas o que estén lactando.

Es posible que las personas con antecedentes de alergia al yodo en la dieta o a los mariscos no puedan someterse a este examen. Sin embargo, un antecedente de alergia al yodo (medio de contraste) no necesariamente quiere decir que usted no pueda practicarse este examen. Consulte con el médico.

Consideraciones especiales:

El yodo radiactivo sale del cuerpo a través de la orina. Es necesario tomar precauciones especiales, como vaciar el baño dos veces después de orinar, durante un período de 24 a 48 horas después del examen. Pregúntele al médico o al encargado de la sala de medicina nuclear o de radiología que lleva a cabo el examen.
