Fig. 5

A 53-year-old female patient (BMI = 26.3) with acute left ureteric colic. a Axial low-dose (0.43 mSv) 2-mm non-contrast CT image reconstructed with 70 % ASiR showing a 5-mm calculus in the lower pole of the right kidney (arrowhead). b Axial conventional dose (5 mSv) 2-mm non-contrast CT image reconstructed with 40 % ASiR showing an additional 1.7-mm renal calculus in the right lower pole (arrow)
