Tomografía por emisión de positrones (TEP) del corazón - Risks

Nombres alternativos

Gammagrafía nuclear del corazón; Tomografía por emisión de positrones del corazón; TEP miocárdica

Riesgos:

La cantidad de radiación utilizada en una TEP es baja y es más o menos la misma cantidad como en la mayoría de las tomografías. Además, la radiación no dura mucho tiempo en el cuerpo.

Las mujeres embarazadas o que están amamantando deben hacerle saber esto al médico antes de realizarse este examen, ya que los bebés y los fetos son más sensibles a los efectos de la radiación, debido a que los órganos aún están creciendo.

Es posible, aunque bastante improbable, tener una reacción alérgica a la sustancia radiactiva. Algunas personas presentan dolor, enrojecimiento o hinchazón en el sitio de la inyección.

Consideraciones:

Es posible obtener resultados falsos en una TEP. Los niveles de glucemia e insulina pueden afectar los resultados del examen en personas con diabetes.

La mayoría de las TEP ahora se llevan a cabo junto con una tomografía computarizada, una combinación denominada TEP/TC.
