The articles were published between January 2000 and October 2018. A full, deep review revealed that most articles were related to the hospital environment. The financial evaluations comprised cost-effectiveness, cost prediction, initial cost reduction, and plummeting transportation and referrals of hospitals all over the world. The comparative evaluation studies usually compared and reviewed the type of pictures sent, the type of image formats, and the various tools for viewing the images in the hospitals. Therefore, the researchers decided to focus on the following themes: economic evaluation, technical evaluation of the system, evaluation of the PACS/RIS system, comparison of teleradiology and non-teleradiology systems, comparison of different instruments used in radiology systems, and the impact of these systems. Themes that were extracted in this article are as follow: comparison of methods or instruments, economic evaluation, technical evaluation, radiology information system (RIS) or picture archiving and communication system (PACS), and teleradiology impacts on hospital settings. With regard to the comparison of methods or instruments, articles compared two methods of teleradiology and non-teleradiology. In some papers, the authors examined various data entry tools and methods of compression. The reviewed articles indicated the impact of RIS or PACS on different aspects, such as workflow, efficiency, and effectiveness. Some articles aimed to evaluate economic, cost-effectiveness, cost-benefit, or any other cost estimation of the application of RIS or PACS.
