This question is discussed in an excellent post on the ED Trauma and Critical Care blog. Amit reviews these four articles:

  1. Newhouse, J. H. & RoyChoudhury, A. (2013). Quantitating Contrast Medium-induced Nephropathy: Controlling the Controls. Radiology, 267(1), 4–8. doi:10.1148/radiol.13122876
  2. McDonald, J. S., McDonald, R. J., Comin, J., Williamson, E. E., Katzberg, R. W., Murad, H. M., & Kalimes, D. F. (2013).
