Kidney Stone In Doppler Ultrasound. The signals on the stone were at least two orders. Twinkling was quantified real time in terms of twinkle power or the magnitude of the color doppler ultrasound signal summed over a fixed 20 20 pixel region of interest that included the kidney stone.
Ultrasonic imaging today is a method of kidney stone detection rarely used because of its variability across users and inconsistency as compared to computed tomography ct scans. These ultrasound images are diagnostic of a renal calculus measuring 15 x 10 mm. Recently it was proposed stable crevice bubbles on the kidney stone surface cause twinkling.
