Teleradiology is the electronic transmission of the radiologic images from one location to another, for the purposes of interpretation or consultation, for sharing studies with other radiologist and physicians. Teleradiology improve education, and requires specific telecommunication infrastructure, by the use of Picture Archiving and Communication System (PACS) and Radiology Information System (RIS). Teleradiology is medical practice of having radiological images read by radiologist who is not on same location where images were generated. Teleradiology improves patients care. Teleradiology utilizes standard network technologies such as internet, telephone line, WLAN (engl. Wide area network) and LAN (engl. Local area network) and computers. Teleradiology use DICOM standard (engl. Digital imaging and communications in medicine) as a standard for transmitting information in medical imaging. The communication protocol is an application protocol that uses TCP/IP protocols to communicate between systems. Through teleradiology and mobile DICOM viewers, images can be sent to another part of the hospital, or to other locations around the world. Teleradiology may improve the quality of life. Teleradiology gives the opportunity to connect with distant radiologist daytime and nighttime. Teleradiology will have significant impact on the development of healthcare and practice in medicine. There is still place for development in teleradiology which includes legal issues and responsibility of teleradiologist. Teleradiolgy is available anywhere, anytime. Key words: Teleradiology, telecommunications, radiology, internet, information system,protocol, DICOM standard.
