X-ray services were first established in Singapore in 1898. With the opening of the General Hospital in 1926, there was subsequent increase in workload. However, a radiology department was not formed until the 1950s. Angiography was introduced in the same decade initially for diagnosis. By the 1960s and 1970s, both vascular and non-vascular interventions were performed. Subsequently, interventional radiology experienced exponential growth, with newer technology and better facilities established over the past 3 decades. With more trained interventional radiologists, the service is currently available in all public hospitals and in most private hospitals in Singapore today. It is envisaged that structured training and formal credentialing will be established, eventually leading to recognition of interventional radiology as a specialty in its own right.
