Teleradiology will have a significant impact on the delivery of healthcare and the practice of medicine. In order to ensure a positive outcome, the expected benefits, limitations and potential pitfalls of teleradiology must be carefully considered. For Singapore, teleradiology can be used to facilitate a quantum leap in the standards of radiological services. This can be achieved through the development of an integrated, nationwide, high-speed radiology network which will allow patients to have access to high-quality and responsive subspecialty radiology expertise located throughout the country. If judiciously implemented, teleradiology has the potential to propel Singapore radiology to an unprecedented level of professional quality and service delivery, and will provide the framework for sustainable radiological insourcing from other countries.
