Abstract

To compare term occurrences in free-text radiology reports and RSNA reporting templates, we selected five templates from an RSNA reporting template library and their corresponding free-text reports as a test set, and employed the Wilcoxon signed-rank test to find out whether the terms in RSNA reporting templates match those terms appearing in corresponding free-text radiology reports. The results show that most terms in free-text radiology reports are covered by RSNA reporting templates. By assessing the terminology coverage of existing templates, this study may benefit the growth of the RSNA reporting template library.
