Brief summary
This study involves the use of Magnetic Resonance Imaging (MRI) contrast agents called gadobutrol (Gadavist) Injection and ProHance Injection. The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of gadobutrol when used for taking MR images of the brain and spine. The results of the MRI with gadobutrol Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with ProHance.
Detailed description
Issues on safety will be addressed in Adverse Events section.
Interventions
Participants received a single dose of gadobutrol 0.1 mmol/kg body weight (bw) via i.v. (intravenous)
Participants received a single dose of gadoteridol at the approved dose, 0.1 mmol/kg bw, via i.v.

Scores for Three Visualization Parameters (Contrast Enhancement, Border Delineation and Internal Morphology) for Combined Unenhanced/Gadoteridol-enhanced MRI Compared to Unenhanced MRI by Average Reader
The AR analysis used the mean of the values for the 3 blinded readers. The 3 BRs evaluated the images from the unenhanced MRI in one session and the images from the combined unenhanced and gadobutrol-enhanced MRIs in another. Contrast enhancement was scored on a 4-point scale where 1 = no enhancement and 4 = excellent enhancement. Border delineation was scored on a 4-point scale where 1 = no or unclear delineation and 4 = excellent delineation. Internal morphology was scored on a 3-point scale where 1 = poorly visible and 3 = sufficiently visible.

Specificity of Detection of Normal/Abnormal Brain Tissue for Combined Unenhanced/Gadobutrol-enhanced MRI Compared to Combined Unenhanced/Gadoteridol-enhanced MRI by Majority Reader Using T1-weighted (T1w) Images
The majority reader diagnosis was the diagnosis provided by at least 2 of the 3 BRs for the T1w assessment (normal or abnormal). The final clinical diagnosis was provided by an independent truth committee following evaluation of findings from referral through a 3-month follow-up period, not including the study-specific MR image sets. Specificity = percentage of participants for which the imaging modality (Gadobutrol-enhanced or Gadoteridol-enhanced) correctly excludes abnormal brain tissue as defined by the independent truth committee.
Time frame: Up to 2 hours after injection of gadobutrol or gadoteridol
Population: All participants in the FAS with assessments for this outcome measure.
