Trial Title: Dose Finding Study of Gadavist in Central Nervous System (CNS) Magnetic Resonance Imaging (MRI)

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: DIAGNOSTIC
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE2
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* Patients with either known or highly suspected focal areas of disruption of the blood brain barrier (BBB) (eg, primary and secondary tumors, focal inflammatory or demyelinating disorders) and/or abnormal vascularity in the CNS, who are scheduled to undergo a routine contrast-enhanced MRI of the CNS.~* Patients with untreated brain tumors should constitute a minimum of 50% of the study population and patients with treated brain tumors will be limited to a maximum of 20% of the study population~Exclusion Criteria:~* Is a female patient who is pregnant or nursing.~* Is a female of childbearing potential and did not have a negative urine pregnancy test the same day as the administration of gadobutrol or comparator treatment.~* Has received any investigational product within 30 days prior to enrolling in this study.~* Has been previously enrolled in this study or any other study using gadobutrol.~* Has any contraindication to the MRI examinations.~* Has a history of severe allergic or anaphylactoid reaction to any allergen including drugs and contrast agents.~* Has received any contrast agent within 24 hours prior to gadobutrol contrast administration, or is scheduled to receive any contrast agent within 72 hours after the gadobutrol study.~* Is considered to be clinically unstable or his/her clinical course during the study period is unpredictable (eg, due to previous surgery, acute renal failure).~* Has been treated with high dose (\>55 cobalt Gy equivalent) photon radiation or global radiotherapy for CNS lesions at any time before entering the study.~* Is scheduled to receive chemotherapy or radiotherapy during the study period.~* Is expected or scheduled to have a change in any treatment or procedure between the comparator and gadobutrol MRIs that may alter their interpretation.~* Is scheduled or is likely to require a biopsy or surgery within the 72 hours after the gadobutrol MRI procedure, or is scheduled for or has undergone such interventions between the comparator and gadobutrol studies.~* Has severe cardiovascular disease.~* Has any contraindication to OptiMARK according to the package insert.~* Has more than 30 brain lesions detected by any prior imaging examination.

Study Arms:
- Gadobutrol~0.03 mmol/kg BW (Gadavist, BAY86-4875) (Type: EXPERIMENTAL): 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.
- Gadobutrol~0.1 mmol/kg BW (Gadavist, BAY86-4875) (Type: EXPERIMENTAL): 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.
- Gadobutrol~0.3 mmol/kg BW (Gadavist, BAY86-4875) (Type: EXPERIMENTAL): 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.

Based on this trial design, predict the completion outcome and termination type (if applicable).
