Brief summary:
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.

Detailed description:
Safety issues are addressed in the Adverse Events section

Arms:
arm 1: Participant received one dose of 0.03 mmol/kg BW of Gadobutrol and one dose of 0.1 mmol/kg body weight (BW) of OptiMARK. The order in which the participants received Gadobutrol and OptiMARK was randomized. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate. arm 2: Participant received one dose of 0.1 mmol/kg BW of Gadobutrol and one dose of 0.1 mmol/kg BW of OptiMARK. The order in which the participants received Gadobutrol and OptiMARK was randomized. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate. arm 3: Participant received one dose of 0.3 mmol/kg BW of Gadobutrol and one dose of 0.1 mmol/kg BW of OptiMARK. The order in which the participants received Gadobutrol and OptiMARK was randomized. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate.

Interventions: intervention 1: Gadobutrol~0.03 mmol/kg BW (Gadavist, Gadovist, BAY86-4875) intervention 2: Gadobutrol~0.1 mmol/kg BW (Gadavist, Gadovist, BAY86-4875) intervention 3: Gadobutrol~0.3 mmol/kg BW (Gadavist, Gadovist, BAY86-4875) intervention 4: OptiMARK~0.1 mmol/kg BW
Intervention descriptions: intervention 1: Participant received one dose of 0.03 mmol/kg BW of Gadobutrol. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate. intervention 2: Participant received one dose of 0.1 mmol/kg BW of Gadobutrol. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate. intervention 3: Participant received one dose of 0.3 mmol/kg BW of Gadobutrol. Gadobutrol was administered via a power injector at a rate of 5 mL/s followed by a 20 mL 0.9% saline flush at the same rate. intervention 4: Participant received one dose of 0.1 mmol/kg BW of OptiMARK. OptiMARK was administered via a power injector at a rate of 2 mL/s followed by a 20 mL 0.9% saline flush at the same rate.
