실험적: 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)).

측정값 설명
기간
Number of Participants With Diagnostic Adequacy - Open-label Clinical Investigators (Per Protocol Set)
기간: 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
기간: 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
기간: 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.
Within 5 minutes after injection
PK Analysis - Total Clearance (CL)
기간: 20 to 45 min and 4 to 8 hours post injection
Total clearance is the fraction of the volume of distribution (Vd) which is completely purified per unit of time and depends also on the plasma half-life of the drug.
20 to 45 min and 4 to 8 hours post injection
PK Analysis - Total Clearance (CL)/Body Weight (BW)
기간: 20 to 45 min and 4 to 8 hours post injection
CL/BW = total clearance normalized by BW
20 to 45 min and 4 to 8 hours post injection
PK Analysis - Volume of Distribution at Steady State (Vss)
기간: 20 to 45 min and 4 to 8 hours post injection
Vss is an estimate of drug distribution independent of the elimination process and is proportional to the amount of drug in the body versus the drug plasma concentration at steady-state.
20 to 45 min and 4 to 8 hours post injection
PK Analysis - Volume of Distribution at Steady State (Vss) /Body Weight (BW)
기간: 20 to 45 min and 4 to 8 hours post injection
Vss/BW = volume of distribution at steady state normalized by body weight
20 to 45 min and 4 to 8 hours post injection
PK Analysis - Area Under the Drug Concentration-time Curve (AUC)
기간: Samples taken 20 to 45 min and 4 to 8 hours post injection. AUC calculated from time of injection to infinity.
AUC = Area under the drug concentration-time curve from administration to infinity
Samples taken 20 to 45 min and 4 to 8 hours post injection. AUC calculated from time of injection to infinity.
PK Analysis - t 1/2
기간: Samples taken at 20 to 45 min and at 4 to 8 hours post injection; t 1/2 calculated from area under the drug concentration-time curve from administration to infinity
t 1/2 = termination elimination half-life calculated from the area under the drug concentration-time curve from administration to infinity
Samples taken at 20 to 45 min and at 4 to 8 hours post injection; t 1/2 calculated from area under the drug concentration-time curve from administration to infinity
