Non-invasive evaluation of the visceral arteries with magnetic resonance angiography.

Abstract

Traditionally, there have been only a few indications for imaging of the visceral arteries. With improvements in treatment of many mesenteric vascular disorders, it has become more important to establish a diagnosis early in the course of the disease. With the advent of ultrasound, computed tomography and magnetic resonance imaging non-invasive imaging of the visceral arteries became possible, although all these modalities were limited in scope for demonstration of mesenteric pathology. The advent of high-quality mesenteric MR arteriography and venography, which allows comprehensive evaluation of both visceral artery anatomy and function, has led to a huge increase in the number of studies directed at the mesenteric arteries in many departments.
