Angiografía por resonancia magnética - Risks

Nombres alternativos

ARM; Angiografía por medio de resonancia magnética

Riesgos:

Una angiografía por resonancia magnética generalmente es un procedimiento seguro y no utiliza ninguna radiación. Hasta la fecha, no se ha informado de efectos secundarios a causa de los campos magnéticos y las ondas de radio.

El tipo de medio de contraste (tinte) utilizado más común es el gadolinio, el cual es muy seguro. Las reacciones alérgicas a esta sustancia rara vez ocurren. Sin embargo, el gadolinio puede ser dañino para pacientes con problemas renales que requieran diálisis. Si usted tiene problemas en el riñón, por favor coméntele al médico antes del examen.

Los fuertes campos magnéticos que se crean durante una resonancia magnética pueden provocar que los marcapasos cardíacos y otros implantes no funcionen igual de bien. También pueden provocar que un pedazo de metal dentro del cuerpo se desplace o cambie de posición.
