Effect of Reconstruction Method on Radiologists' Preference, Full Dose Image

Note.- Combined data from two observers. 1 = strongly preferred F-FBP image, 2 = somewhat preferred F-FBP image, 3 = no preference, 4 = somewhat preferred F-IRIS image, 5 = strongly preferred F-IRIS image. In Wilcoxon's rank sum test, p < 0.05 indicates significant difference. F/FBP = full dose image with filtered back projection, F/IRIS = full dose image with iterative reconstruction in image space (IRIS, Siemens Healthcare, Erlangen, Germany)
