Summary
Brief summary
This study involves the use of Magnetic Resonance Imaging (MRI) contrast agents called gadobutrol (Gadovist®) 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®.
