Teleradiology is probably the most advanced part of telemedicine in the United States. For nearly a decade almost all radiologic exams have been digital. The film era of radiology passed into history around the turn of the century.
Since radiologists interpret digital images on a computer workstation using picture archiving and communications software (PACS), the radiologist’s location does not really matter as long as the digital images can be easily transmitted to his or her workstation and the formal radiologic report can be transmitted to the patient’s physicians or other healthcare providers. This transmission of images and reports is usually internal to a hospital or medical center, but it can be across town or across the country.
