CT dose reductions don't impede detection of large renal calculi
By Eric Barnes
For detecting renal calculi with CT, even dose reductions as high as 75% didn't reduce sensitivity for stones 3 mm and larger, according to a new study from Ohio's Cleveland Clinic. And because smaller stones are more likely to pass, significant dose reductions may be possible without missing the larger and more problematic calculi.
