Gammagrafía de la vesícula biliar con radionúclidos

Toggle: English / Spanish

La gammagrafía de la vesícula biliar con radionúclidos se realiza inyectando un trazador químico radioactivo en el torrente sanguíneo. Para realizar el examen se utiliza una gammacámara. Ésta detecta los rayos gamma al ser emitidos desde el rastreador y la imagen del lugar donde se encuentra el rastreador en el órgano es transmitida a una computadora. Este examen es muy bueno para detectar infecciones agudas (colecistitis) o la obstrucción de un conducto biliar. También es útil para determinar si existe rechazo en el caso de un trasplante de hígado.
