Severe acute respiratory syndrome (SARS) is an emerging infection that is caused by a novel coronavi-rus [1-3]. Since its first outbreak in the Guan-dong province in southern China in November 2002, until now, 8,046 people have been infected [4]. The global case number is still growing every day. In Hong Kong, more than 1,722 individuals have been infected, with 193 patients admitted to our hospital as a result of an outbreak in a high-rise housing development.
The radiology department plays a pivotal role in the diagnosis and management of SARS [5, 6]. Although chest radiography remains the most commonly used imaging modality in the investigation and treatment of patients with SARS, subtle changes such as ground-glass opacities, which are readily identifiable on high-resolution CT, are easily overlooked [7, 8].
