Teleradiology of radiological patient images, such as x-rays, CTs, and MRIs, from one location to another for the purposes of interpretation and/or consultation What is Tele-Radiology Why is Tele-Radiology Needed Teleradiology improves patient care by allowing Radiologists to provide services without actually having to be at the location of the patient. Radiologists are increasingly a scarce resource, given that imaging procedures are growing by ~15% annually against an increase of only ~2% in the Radiologist population The virtual radiology network (VRN) is a modern service for radiology groups that collects digital imaging studies from multiple, geographically-dispersed locations and delivers them securely, reliably and efficiently to physicians over the Web. Teleradiology improves patient care by allowing Hospitals to outsource subspecialty expertise needed but not found except in big cities. Tele-Radiology, Definition

Dealing with Emergency Cases: Tele-Radiology, Emergency Cases Study Identification N : Normal Study (No report needed) R : To be Reported E : Emergency etc. Study Identification N : Normal Study (No report needed) R : To be Reported E : Emergency etc. The report is sent back to the Hospital The Technician identifies the case as an Emergency The Case is sent to the PACS Server with High Priority Emergency case is sent to the Data Center before any Normal Case Emergency case is sent to the Service Provider to be reported The case is reported and sent back to the data center
