3T MR-imaging of rats with acute ischemic renal failure, Cyclosporin A toxicity and control was performed 36h after injection of ultra small particles of iron oxide (P904). Only in the acute renal failure signal decay in the medulla was seen which correlated with positive iron findings and Ed1 positive macrophages in immunohistology.
