Medical records are reviewed to obtain information about the use of a MRI diagnostic imaging agent (contrast agent) called Primovist/Eovist in children older than 2 months and less than 18 years. Data that has been recorded in the child's medical records relating to the injection of Primovist/Eovist will be collected. Information will be collected from up to 2 weeks before the child received Primovist/Eovist until 12 months after the child received Primovist/Eovist. Copy of the child's MR images that were taken right before and after the child received Primovist/Eovist and all other reports (laboratory reports, other imaging reports, etc) that are part of the child's medical records during that time period will be collected.

Percentage of Participants With Overall Change in Additional Diagnostic Information Obtained When Comparing the Combined Precontrast/Postcontrast Images With the Precontrast Images.
Overall Change in additional diagnostic information was defined as a change in at least 1 of the 5 variables below obtained from the combined precontrast and postcontrast images as compared with the precontrast images: 1. Change in number of lesions: greater or fewer 2. Improved border delineation of the primary lesion 3. Increased contrast of primary lesion versus. background 4. Change in size of the primary lesion: larger or smaller 5. Change in information about lesion characterization (lesion type): improved, unchanged, worsened
Time frame: When precontrast and postcontrast images are available from all enrolled subjects, on average 1 year post Primovist/Eovist MRI
Number of Participants With Laboratory Values Considered to be Clinically Relevant Values or Abnormalities at Pre-injection Time Point
Laboratory parameters analyzed: Hematology: leukocytes, erythrocytes, hematocrit, platelets, hemoglobin, prothrombin time and differential counts (neutrophils total, neutrophils segmented and lymphocytes); Chemistry: lactate dehydrogenase (LDH), alkaline phosphatase (AKP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), sodium, potassium, blood urea nitrogen (BUN), glucose, creatinine, bilirubin:, direct bilirubin, indirect bilirubin, total protein, albumin, estimated glomerular filtration rate (eGFR), and α-fetoprotein levels.
Time frame: 14 days prior to Eovist/Primovist MRI

Final Diagnosis (SoT) by Clinical Investigator
Time frame: When precontrast and postcontrast images are available from all enrolled subjects, on average 1 year post Primovist/Eovist MRI
Sensitivity, Specificity and Accuracy of Blinded Read of Precontrast and Combined Precontrast/Postcontrast Images Based on Final Diagnosis.
Sensitivity is the probability that a test indicates there is disease when there is disease. Specificity is the probability that a test indicates there is no disease when there is no disease. Accuracy is the probability that a test is correct: the test indicates there is no disease when there is no disease and it indicates there is disease when there is disease.
Time frame: When precontrast and postcontrast images are available from all enrolled subjects, on average 1 year post Primovist/Eovist MRI
