A Single-blind, Multicenter, Randomized, Phase III Study of the Efficacy and Safety of Gadavist (1.0 M) in Comparison With Magnevist (0.5 M) as Contrast Agent for Enhanced Magnetic Resonance Imaging (MRI) of Central Nervous System (CNS) Lesions in Chinese Patients
The purpose of this study is to determine if the contrast agent is effective and safe in the Magnetic Resonance Imaging (MRI) of brain or spine diseases in patients of Chinese origin.

Conditions
- Central Nervous System Diseases
Interventions
- Gadobutrol (Gadavist, Gadovist, BAY86-4875)
- Magnevist
Primary outcomes
- Change in Contrast to Noise Ratio (CNR) Between Pre- and Post-contrast Magnetic Resonance Imaging (MRI) Scan of Central Nervous System (CNS) Lesions — Immediately before injection (pre-contrast) and 2-5 min after injection (post-contrast)
CNR = (signal intensity \[SI\] lesion - SI normal tissue) / standard deviation (SD) background. SI lesion is the signal intensity in the lesion, SI normal tissue is the signal intensity in the normal tissue, and SD background is the standard deviation of the background noise. The signal intensity (SI) on the pre-contrast and on the post-contrast MR scans was to be measured in the enhanced lesion, normal tissue and background.
