Resonancia magnética de la pelvis - Risks

Nombres alternativos

IRM de la pelvis; IRM de las caderas; IRM pélvica; IRM con sonda prostática; Imágenes por resonancia magnética de la pelvis

Riesgos:

La resonancia magnética no contiene ninguna radiación y, 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 otros pedazos de metal dentro del cuerpo se desplacen o cambien de posición.

Consideraciones:

Los exámenes que pueden hacerse en lugar de una resonancia magnética de la pelvis abarcan:

  • Tomografía computarizada del área pélvica
  • Ecografía vaginal (en mujeres)
  • Radiografía del área pélvica

Se puede hacer una tomografía computarizada en casos de emergencia, ya que es más rápida y normalmente está disponible directamente en la sala de urgencias.
