A Study to Evaluate the Safety and Diagnostic Effectiveness of Mangoral in Patients With Focal Liver Lesions and Reduced Kidney Function


About this study

The overall purpose of this study is to evaluate the safety and diagnostic effectiveness of Mangoral in liver MRI in patients with known or suspected focal liver lesions and severe renal impairment. The diagnostic efficacy of Mangoral will be assessed in terms of visualization of detected focal liver lesions in combined MRI (CMRI: combined Mangoral-enhanced and unenhanced MRI) compared to unenhanced MRI.
