Sperimentale: Gadopentetate dimeglumine (Magnevist, BAY86-6661)
For stage 1: Participants received an IV injection of 0.05 mmol/kg Body Weight (BW) (0.1 mL/kg BW) Magnevist.
Upon completion of the MR imaging, the participants received another injection of 0.05 mmol/kg for a total cumulative dose of 0.1 mmol/kg BW (0.2 mL/kg BW).
For stage 2: Participants received the optimal efficacious dose established in Stage 1 as a single IV injection of Magnevist Injection (0.1 mmol/kg BW (0.2 mL/kg BW)).

Number of Participants With Diagnostic Adequacy - Open-label Clinical Investigators (Per Protocol Set)
Lasso di tempo: Within 5 minutes after injection
|
A clinical judgment by the open-label Clinical Investigators (CIs) as to whether ("yes") or not ("no") the CI could make a diagnosis from the image.
|
Within 5 minutes after injection
|
|
Dose Determined by Blinded Readers to be Superior for Diagnosis
Lasso di tempo: Within 5 minutes after injection
|
Dose superiority was a calculation based upon the Blinder Readers' assessment of 4 visualization parameters
|
Within 5 minutes after injection
|
|
Paired-dose Comparison of Number of Participants With Dose Superiority Determined for 4 Lesion Visualization Variables - Blinded Readers
Lasso di tempo: Within 5 minutes after injection
|
For each participant, the Blinded Reader indicated which dose had better contrast enhancement, better border delineation, clearer internal morphology, and provided more diagnostic information.
The dose chosen for 3 or 4 of these variables was the selected dose for that Reader and participant.
If each dose was superior on 2 variables, the dose which provided more diagnostic information was selected for that participant.
The dose selected for the majority of participants was the dose selected by that Reader; if chosen by 2 or 3 Readers, it was the selected dose.

20 to 45 min and 4 to 8 hours post injection
|
|
PK Analysis - Volume of Distribution at Steady State (Vss) /Body Weight (BW)
