Gammagrafía ósea - Risks

Nombres alternativos

Gammagrafía del hueso

Riesgos:

Si usted se encuentra embarazada o en período de lactancia, el examen se puede aplazar para prevenir la exposición del feto a la radiación. Si usted tiene que someterse al examen mientras esté amamantando, debe extraer y botar la leche materna durante los próximos dos días.

La cantidad de radiación inyectada dentro de la vena es muy pequeña y casi toda desaparece del organismo al cabo de 2 a 3 días. El marcador radiactivo que se utiliza lo expone a usted a una cantidad muy pequeña de radiación y el riesgo probablemente no es mayor al riesgo de las radiografías de rutina o convencionales.

Los riesgos relacionados con el marcador radiactivo en el hueso son raros, pero pueden abarcar:

Hay un ligero riesgo de infección o sangrado cuando se introduce la aguja dentro de la vena.

Consideraciones:

Algunas anomalías que se pueden identificar en la gammagrafía ósea con radionúclidos son:

  • Artritis y otras enfermedades degenerativas de los huesos
  • Necrosis avascular
  • Infecciones óseas (osteomielitis)
  • Tumores óseos
  • Displasia fibrosa
  • Fracturas
  • Enfermedad de Paget
  • Cambios de radiación
  • Raquitismo
  • Tumores que se han diseminado de otras partes del cuerpo al hueso (enfermedad metastásica)

Es importante entender que los hallazgos de la gammagrafía ósea deben compararse con otros estudios imagenológicos, además de la información clínica. Usted debe discutir el significado de los hallazgos anormales con su médico.
