Brief summary
The purpose of the 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 body/extremities regions. 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 Magnevist.
