24. Any other condition that may confound the results of the trial or presents an unacceptable risk for any study-related procedure
25. Individuals who are unable to fully understand all aspects of the investigation that are relevant to the decision to participate, or who could be manipulated or unduly influenced as a result of a compromised position, expectation of benefits or fear of retaliatory response
26. Presence of any condition that precludes administration of furosemide during renograms
27. Unable to tolerate contrast related to required study procedures or imaging.
