Radiology and mesenteric ischaemia.

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. Looking to the future, we also assess some of the emerging imaging techniques. Across medicine and surgery there has been a significant shift towards minimally invasive interventions. 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.
