Aortic penetrating atherosclerotic ulcer (PAU) is a relatively common incidental finding on thoracic computed tomography (CT) examinations. This is likely to relate to the steady increase in the number of CT examinations performed and also due, in part, to the increasing age of the general population. There is as yet no consensus on the management of incidental PAUs in asymptomatic patients. This article aims to review the literature and discuss the natural history, prognosis, and management of incidental PAU.

To describe the sequential appearance of healing rib fractures on initial and follow-up radiographs using published guidelines in approximating the age of rib fractures in infants with the aim of establishing a more objective method of dating rib fractures by measuring the thickness of the callous formation. ⋯ It appears that rib fractures in infants follow a predictable pattern of healing. Measuring the thickness of the callous formation is a more objective way of guiding the radiologist in estimating the age of the fracture.

To assess diffusion changes in the remote white matter and areas of white matter with cerebral artery obstruction without magnetic resonance imaging (MRI) evidence of brain parenchymal abnormalities using high b-value diffusion tensor imaging (DTI). ⋯ High b-value DTI could sensitively reveal diffusion changes in white matter in regions of cerebral artery obstruction without abnormal anisotropy and diffusivity of the remote white matter of patients with severe MCA stenosis or occlusion without MRI evidence of brain parenchymal abnormalities.

To evaluate the clinical impact and cost-effectiveness of a multidisciplinary team (MDT) meeting in a large hospital in the UK. ⋯ The costs of MDT meetings are very high producing a small clinical impact. At a time of increasing financial and capacity pressure in healthcare systems, the use of scarce resources may be better deployed elsewhere.
