Resonancia magnética de la rodilla - Risks

Nombres alternativos

IRM de la rodilla

Riesgos:

La resonancia magnética no contiene ninguna radiación ionizante y hasta la fecha no ha habido informes de efectos secundarios significativos de los campos magnéticos y de las ondas de radio utilizadas en el cuerpo humano.

El tipo de medio de contraste utilizado más común es el gadolinio, el cual es muy seguro. Las reacciones alérgicas a esta sustancia rara vez ocurren. La persona que opera la máquina vigilará la frecuencia cardíaca y la respiración, en la medida de lo necesario.

La resonancia magnética generalmente no se recomienda para situaciones de traumatismo agudo, debido a que el equipo de tracción y de soporte vital no puede ingresar al área del escáner de manera segura y el examen puede tomar algo de tiempo.

Algunas personas se han lesionado en las máquinas de resonancia magnética cuando no se quitaron los objetos metálicos de sus ropas o cuando otras personas dejaron objetos de metal en el cuarto.

Consideraciones especiales:

Los exámenes que se pueden hacer en lugar de una resonancia magnética de la rodilla abarcan:
