workload and yet to provide the greatest possible value to the patients. Contribution of a radiologist to a correct and timely imaging report is key for the right treatment decision. In our opinion, the first step toward creating value for patients referred to the radiology department starts with assuring the appropriateness of the imaging examinations. There are statistics showing that up to 20% of all requests in Europe and up to 50% in the USA are not appropriate. 2,3 In this regard, the radiologist should play a pivotal role in providing the right examination for the right clinical indications, and, if necessary, to reject unnecessary or redundant imaging requests. The reality, however, is somewhat complex. In many situations, especially in the case of outpatients, the information coming with the request for the radiological examination is minimal. A promising technical support could be provided by the clinical decision support (CDS) systems, which ensure whether the modality requested to the examination and patient condition is in line with currently valid guidelines. CDS systems prove, whether MRI or CT, with or without contrast agent, is the most appropriate imaging modality to answer the given clinical question. Preferably, these systems should be fed with additional information from the electronic health record (EHR) of the patient (for example, renal function, pregnancy, HIV status, diabetes). Beyond choosing the right modality, an intelligent CDS system should even be able to assign the appropriate protocol, examination lane, dose, volume of contrast, number of phases, and additional The main challenge the field of radiology is facing nowadays is to handle an ever-increasing workload and yet to provide the greatest possible value to the patients sequences in MRI, to help adequately address the medical question. In other words, CDS should help tailor and personalise examination protocols. Dose management of imaging examinations involving radiation exposure goes hand in hand with the appropriateness check, which is a part of the radiologist’s and medical physicist’s responsibility. When implemented adequately, CDS systems will increase productivity, reduce unnecessary examinations and save resources. The radiologists will benefit from time saved to engage more on patient care, whether it is appropriate reporting, communication of diagnosis or follow-up of treatment results. In order to harmonise imaging appropriateness criteria throughout European countries, the European Society of Radiology (ESR) has launched a computer-based CDS tool called ESR iGuide. This tool provides a core standard system, with guidelines adaptable to local (national and institutional) situations. 4 Picture archiving communications systems (PACS) have revolutionised radiology in every sense. The downside of computerisation is, however, reduced in-person consultation between the treating clinicians and the radiology departments. In general, images are analysed and annotated in the PACS; radiology reports are then created mostly as a narrative text and deposited in the EHR or sent to the referring physician in a hard copy. According to a recent study, one third of radiologists’ recommendations contained in written reports are ignored or even not documented in the patient medical record by the referring physician. 5 One approach to address this issue is the improvement of radiology reports by structuring and standardising. The solution is to be expected from IT development. Similar to a checklist, structured reports have a template with standardised content and standardised language. According to recent studies, structured radiology reports are more complete and have more relevant content. 6,7 Moreover, improved linguistic quality of structured repo
