TSR guidelines for the practice of teleradiology: 2021 update*

Mustafa N. Ozmen ABSTRACT Oğuz Dicle This update of Turkish Society of Radiology’s (TSR) guidelines for the practice of teleradiology Utku Şenol is intended to provide a reference framework for all parties involved in delivering imaging services away from the immediate vicinity of the patient. It includes relevant definitions and Üstün Aydıngöz general principles, features organizational modes and qualifications of the practicing parties, lists technical issues, and addresses such management and legal aspects as archiving and documentation, security and privacy, reliability, responsibilities, quality inspection and im- provement, reimbursement and accountability.

uidelines in the form of standards for the practice of teleradiology in Turkey were first published in 2010 (1). This decennial update was prepared in consideration of G the evolving nature of imaging technologies and medical informatics as well as the changing character of the patients’ and public’s demands. These guidelines have been prepared with the aim of providing advice on the appropri- ate use of teleradiology applications, thereby increasing the impact of their contribution to public health. They comprise recommendations and are not intended to fill legal gaps. They are prepared—and expected to be implemented—with a view to highlighting a pa- tient-oriented and good clinical practice approach. The application of other requirements and prerogatives not defined in these guidelines, specific to any clinical situation, is at the discretion of the responsible physician who performs or oversees the radiological service or renders its interpretation. Provided that they are carried out in accordance with guidelines, teleradiology allows the reporting of radiological examinations in a shorter time, renders this process possible independent of time and place, facilitates easy consultation when necessary, and makes possible continuous training and assessment/appraisal processes. Thanks to teleradiology, users in different locations can view radiological images simultaneously. Teleradiology is a means of maintaining health service without interruption during disasters and other ex- traordinary circumstances (2–6). The use of teleradiology should not diminish the radiologist’s responsibilities for the supervision and management of the entire process of radiology service, which comprises steps to select the most appropriate examination for the patient, to make the examina- From the Department of Radiology (M.N.Ö.  [email protected], Ü.A.), Hacettepe tion at the most appropriate time and with the pertinent protocol, to prepare the patient University School of Medicine, Ankara, Turkey; for the examination, to select and prescribe the appropriate contrast material when its Department of Radiology (O.D.), Dokuz Eylül University School of Medicine, İzmir, Turkey; use is beneficial, to perform the examination in a way that minimizes the harm, especial- Department of Radiology (U.Ş.), Akdeniz University School of Medicine, Antalya, Turkey; On behalf of the ly radiation, to the patient and staff, to provide on-site supervision and quality control Turkish Society of Radiology’s of the examination, to evaluate the images from the examination in light of clinical and Education and Research Group. laboratory information and previous examinations, to communicate the imaging find- * These guidelines were endorsed by the TSR Executive Board on May 15, 2021. ings by preparing a report that includes differential diagnosis and recommendations, and to archive the patient’s radiological images and report with appropriate methods.
