Abstract

A controlled experiment which simulated the standard reporting practices used by radiologists was performed on IRIS to (1) assess the quality of reporting using digital images and (2) evaluate the use of enhancement tools. Reports generated by 5 experienced radiologists using IRIS were compared to reports generated by the same radiologists using analog films on the same emergency department cases at least seven months earlier. In 100 cases, nine findings were missed using IRIS and 14 new findings were identified using IRIS. To make diagnoses, enhancements which caused the image to be darker and increased contrast were most frequently used. There was no systematic relationship between the enhancement tools used and different types of cases.
