Fig. 2E —Effect of noise addition (simulated tube current reduction) in 44-year-old obese woman with renal colic. With simulated tube currents of 130 mA (D) and 70 mA (E), this periuterine calcification becomes less evident. At simulated tube current of 70 mA (E), increased noise could be mistaken for ureteral calculi (arrows, E).
