A computer-implemented system for extracting and displaying a missing concept term to the author of a medical diagnosis or treatment report when the author is editing the report , comprising - a set of stored associations , wherein each association links at least one first concept term in similar reports in a medical knowledge domain with at least one second concept term in the similar reports, wherein the association indicates a frequent co-occurrence of the at least one first concept term and the at least one second concept term in those reports; - a concept term extractor arranged for extracting the at least one first concept term from an at least partially completed report relating to a particular patient being edited in the system by an author, the report being comprised in a data record relating to the particular patient and stored in the system; - a missing concept term finder arranged for checking whether at least one second concept term linked to the at least one first concept term based on the set of associations is missing from the at least partially completed report , and if so outputting the at least one missing second concept term ; - an indicator arranged for displaying to the author the at least one second concept term that is output by the missing concept term finder , when the author is editing the report ; - and a report creation tool for enabling the author to create at least part of the report , wherein the indicator is arranged for displaying the at least one second concept term during a process of creating the at least part of the report ; - wherein the at least one second concept term comprises an anatomical region term, and wherein the system further comprises an image viewer configured to indicate to the author a view of an anatomical region of the patient based on the anatomical region term, wherein the anatomical region corresponds to the anatomical region term. - a set of stored associations , wherein each association links at least one first concept term in similar reports in a medical knowledge domain with at least one second concept term in the similar reports, wherein the association indicates a frequent co-occurrence of the at least one first concept term and the at least one second concept term in those reports; - a concept term extractor arranged for extracting the at least one first concept term from an at least partially completed report relating to a particular patient being edited in the system by an author, the report being comprised in a data record relating to the particular patient and stored in the system; - a missing concept term finder arranged for checking whether at least one second concept term linked to the at least one first concept term based on the set of associations is missing from the at least partially completed report , and if so outputting the at least one missing second concept term ; - an indicator arranged for displaying to the author the at least one second concept term that is output by the missing concept term finder , when the author is editing the report ; - and a report creation tool for enabling the author to create at least part of the report , wherein the indicator is arranged for displaying the at least one second concept term during a process of creating the at least part of the report ; - wherein the at least one second concept term comprises an anatomical region term, and wherein the system further comprises an image viewer configured to indicate to the author a view of an anatomical region of the patient based on the anatomical region term, wherein the anatomical region corresponds to the anatomical region term. <EOS>
