To identify predictors of acute ischaemic stroke (AIS) and evaluate the diagnostic yield and impact of magnetic resonance imaging (MRI) in patients imaged for dizziness and vertigo. ⋯ MRI plays an important role in differentiating peripheral and central aetiology when this proves challenging clinically. Predictors of AIS were identified that aid patient selection for MRI, to increase the yield and impact of neuroimaging.

This review focuses on the radiology of mesenteric ischaemia. Covering the acute and chronic presentations, both of which result from impaired vascularisation of the gastrointestinal tract, we evaluate the role of radiographs, ultrasound, CT, MRI, and catheter angiography in the diagnosis of these conditions. ⋯ Although percutaneous revascularisation of chronic mesenteric ischaemia has been performed for some time, there has been a developing trend for the use of such techniques in acute mesenteric ischaemia. We evaluate the available evidence for the use of these percutaneous interventions and assess how they compare with or in some instances compliment traditional surgical alternatives.

Review
The evolving role of MDCT in the assessment of patients with chronic obstructive pulmonary disease.
The purpose of this article is to educate the reader in the value a radiologist can offer in the multidetector (MD) CT assessment of patients with chronic obstructive pulmonary disease (COPD). MDCT can identify patients in whom treatments such as lung volume reduction surgery or newer endobronchial therapies may be of benefit. We will also discuss important and under-recognised associated cardiorespiratory disease, which may be incidentally identified.
