Sufficient knowledge and accuracy when measuring these features are therefore essential. The objective of this study was to evaluate the variation in measurements and anatomical classifications of LLNs before and after training.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Fifty-three Dutch radiologists examined three rectal MRI scans and completed a questionnaire. Presence, location, size, and suspiciousness of LLNs were reported. This assessment was repeated after a 2-hour online training by the same radiologists with the same three cases plus three additional cases. Three expert radiologists independently evaluated these 6 cases and served as the standard of reference.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Correct identification of the anatomical location improved in case 1 (62 to 77% (<jats:italic>p<\/jats:italic> = .077)) and in case 2 (46 to 72% (<jats:italic>p<\/jats:italic> = .007)) but decreased in case 3 (92 to 74%, <jats:italic>p<\/jats:italic> = .453). Compared to the first three cases, cases 4, 5, and 6 all had a higher initial consensus of 73%, 79%, and 85%, respectively. The mean absolute deviation of the short-axis measurements in cases 1\u20133 were closer\u2014though not significantly\u2014to the expert reference value after training with reduced ranges and standard deviations.
