Study Overview

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.

Primary Outcomes

Number of Lesions for Combined Unenhanced/Gadobutrol-enhanced MRI Compared to Unenhanced MRI by Blinded Readers

Time Frame: Up to 2 hours after injection of gadobutrol

The blinded readers evaluated the images from the unenhanced MRI in one session and the images from the combined unenhanced and gadobutrol-enhanced MRIs in another to determine the total number of lesions.
