Correlation between Twinkling Artifact and Color Doppler Carrier Frequency: Preliminary Observations in Renal Calculi
Ultrasound in Medicine and Biology, 06/15/2012
Gao J et al. – The authors conclude that the strength of the twinkling is color Doppler carrier frequency–dependent. The strength of the twinkling significantly increased when the color carrier frequency used for imaging decreased. Therefore, to improve renal calculi detection by enhancing the strength of the twinkling, the use of a lower color Doppler carrier frequency is recommended.
