*, numbers indicate patients who changed severity classification with the use of ASIR-V and DLIR. mod., moderate; ASIR-V 50%, adaptive statistical iterative reconstruction-V at 50% intensity; DLIR-L, DLIR-M, and DLIR-H: deep learning image reconstruction at low, medium, and high levels, respectively.
