ABSTRACT
Introduction The diagnosis of chronic mesenteric ischemia (CMI) is challenging and for the most part relies on patient history and physical examination, in combination with an imaging diagnostic test showing significant stenosis of more than one mesenteric artery. Until recently, conventional and digital subtraction angiography (DSA) were considered the imaging techniques of choice for the diagnosis of mesenteric arterial stenosis. However, the development of non-invasive angiographic modalities such as computer tomographic angiography (CTA) and magnetic resonance angiography (MRA) have been shown to provide accurate anatomical detail and have challenged conventional angiography as the gold-standard test for the diagnosis of mesenteric arterial stenosis. In the present chapter we will discuss these three diagnostic imaging techniques for the diagnosis of mesenteric arterial stenosis.
