Lung cancer is the leading cause of cancer-related death around the world, being the top cause of cancer-related deaths among men and the second most common cause of cancer-related deaths among women in Singapore. Currently, no screening programme for lung cancer exists in Singapore. Since there is mounting evidence indicating a different epidemiology of lung cancer in Asian countries, including Singapore, compared to the rest of the world, a unique and adaptive approach must be taken for a screening programme to be successful at reducing mortality while maintaining cost-effectiveness and a favourable risk-benefit ratio. This review article promotes the use of low-dose computed tomography of the chest and explores the radiological challenges and future directions., (Copyright: © Singapore Medical Association.)

Paediatric postmortem imaging is distinct and different from adult postmortem imaging due to differences in disease aetiology, pathology and imaging approaches, which require a particular skill set to maximise its yield and clinical utility. Practitioners need to have expertise in several aspects of radiology, including both plain radiographs and cross-sectional imaging modalities, knowledge of specialist techniques, and familiarity with the unique range of pathologies in this patient population, including perinatal pathology. Here we outline the training requirements that should be considered to establish such a service.

Emergency medicine has emerged as a specific medical specialty for 30 years. To be efficient, the emergency clinician frequently needs the contribution of radiological examinations. This is the reason why emergency radiology has emerged as a new radiologic subspecialty. The aim of this paper is to review the recent history of emergency medicine and to summarize the present state of the radiological organisation for emergency care in the Western countries.

The round table discussions dealt with standardisation and its role in PACS and medical imaging, and with the assessment of medical imaging and targeting R & D based on that. Two approaches to enable image files to be transferred were discussed in the standardisation sessions. Firstly, the standardisation efforts in Europe, USA and Japan which all focus on a single standard on image transfer and file format were discussed. A plea was made to merge these three approaches. It was also noted that the Japanese IS&C standard is essentially a standard for off-line PACS. Secondly, an argument was raised that as several i age file formats are already in existence (because of the different computer platforms in use), what is needed are converters between these de-facto formats instead of striving towards one common standard. The round table on assessment focused on the changes in the radiological practices which are already emerging following the introduction of new digital imaging modalities. It was argued that PACS will cause further organisational changes because a hospital-wide PACS enables images to be viewed everywhere. The radiology meetings have been the mechanism for discussing difficult cases. In the PACS world their role may change. However, PACS will only diffuse when it offers clear advantages over the present procedures. This means that PACS, digital imaging and radiology practices evolve in parallel and incrementally.
