The Evolution of Radiology from Paraclinical to Clinical



Download PDF


The perception of Radiology in the early 60s as paraclinical stems from the poor image the clinicians had for our limited resources in providing only plain film studies, VIPs and the single contrast barium studies which exclude only gross lesions. The evolution to clinical status started as early as the mid 60s. My personal recollection and reflection of the histological events that took place covered here highlights the reasons for the transformation from paraclinical to clinical and these form the main theme for this paper. Radiologists’ professionalism plays an infinite part in the evolution to clinical Radiology. Rapid technological advances in imaging help to propel Radiology to the forefront. But credit must go to the individual Radiologist for their personal efforts and contributions. Reflection on past events of Radiology in Singapore leading to the establishment of Clinical Radiology was presented. The future of Radiology is brought up for discussion on the role of Radiologists with reference to subspecialisation necessitated by the ever increasing advances in Medical Imaging and demand for Interventional Radiology.

I would like to thank the Academy of Medicine and the Singapore Radiological Society for giving me the honour of delivering this year’s F Y Khoo’s Memorial Lecture. I believe that I am one of the few radiologists in Singapore who had the privilege of working with Dr F Y Khoo when I joined the Department of Radiology in 1964 at Dr Chow Khuen Wai’s prompting. Dr Khoo headed the department of two disciplines diagnostic and radiotherapy, practising both as a therapeutic as well as diagnostic radiologist.
