ABSTRACT

The scintillation or twinkling artifact is a not fully understood phenomenon that appears in Color Doppler Ultrasound (U.S.) examinations as a rapid alternation of color immediately behind a stationary echogenic object, giving it a false appearance of movement. This sign is useful in some clinical conditions, especially in urolithiasis, since it increases diagnostic accuracy and sensitivity; therefore, every radiologist should be fully acquainted with this radiologic sign.


El artefacto de centelleo en Doppler color es un fenómeno de origen no bien precisado, que se genera detrás de algunas estructuras ecogénicas y que se manifiesta por una alternancia de colores, sin existir movimiento. Este signo es de utilidad en algunas condiciones clínicas, especialmente en la urolitiasis, aumentando la sensibilidad diagnóstica, por lo que debe ser parte del conocimiento de todo radiólogo.
