The administration of contrast agents that contain gadolinium such as Gadovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Gadovist. Patients who are enrolled in this study will receive a Gadovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
