The performance of sub-mSv CT for the detection of stones was analyzed by two readers and compared with that of standard-dose CT.

The mean effective radiation doses of sub-mSv CT was 0.3 mSv. The sensitivity and specificity values for diagnosis of stones measuring \u22653\u2009mm was 95.1% and 100% for sub-mSv CT. The sensitivity and specificity for all stone detection was 74.9% and 97.8%, respectivey, for sub-mSv CT.
