Text: Imaging with 80 kVp instead of 100 kVp was associated with 47 % lower median radiation dose (median dose-length product, 62. 0 mGy cm [interquartile range, 54. 0-123. 3 mGy cm] vs 117. 0 mGy cm [110. 0-225. 9 mGy cm], respectively ; 0. 9 mSv [0. 8-1. 7 mSv] vs 1. 6 mSv [1. 4-3. 2 mSv] ; p < 0. 001 for each) with no significant difference in interpretability (99 % vs 99 % ; p = 0. 99) or image quality (median score, 4. 0 [interquartile range, 3. 6-4. 0] vs 4. 0 [interquartile range, 3. 8-4. 0] ; p = 0. 20).
