The t-SLIP Investigational Study Sequences are designed to compare t-SLIP to standard MR contrast enhanced imaging techniques to establish the diagnosic benefits of t-SLIP compared to contrast enhanced MR techniques. The t-SLIP Investigational Study Sequences will be used for vascular MRI Imaging including, but no limited to, MRA of the renal, mesenteric, abdominal aortic, iliac and femoral arteries. We will be targeting all adult patients undergoing standard body MRA examinations without anesthesia.
