MBIR shows superior noise reduction and improved image quality. Substantial dose reduction can be achieved by increasing the NI parameters as tested in this study without affecting image quality and diagnostic confidence.

Intramural haematoma of the oesophagus is an uncommon and under-recognized condition. It may mimic other causes of chest pain, haematemesis, or dysphagia, and hence pose a diagnostic challenge. We report a case of an unusual presentation of intramural haematoma of the oesophagus occurring as a presumed complication of endotracheal intubation. It was disguised as acute onset post-operative chest pain, and resolved with conservative management. Awareness of this uncommon complication is important to allow rapid and timely diagnosis and management. We review the literature, causes and imaging features of this condition.
