Contrast-induced nephropathy: contrast material not required?
OBJECTIVE
This commentary deals with the study by Newhouse and colleagues in this issue of the AJR discussing the implications of a lack of a control group in previously published studies on contrast-induced nephropathy (CIN).


CONCLUSIONS
Until more rigorous studies including an appropriate control group address the issue of CIN, our understanding of the actual risk of CIN when administering IV contrast media is limited.
