HIRSCH S, Michael; PALAVECINO B, Tamara  y  LEON R, Boris. Twinkling artifact in color Doppler ultrasound: A misunderstood and useful sign . Rev. chil. radiol. [online]. 2011, vol.17, n.2, pp. 82-84. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082011000200006.

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.
