Measure Type	Secondary
Measure Title	Sensitivity of Detection of Malignant Lesions (ML) for Combined Unenhanced/Gadobutrol-enhanced MRI Compared to Unenhanced MRI by Clinical Investigator
Measure Description	The presence of malignant lesions was derived from the diagnoses given by the investigator on the evaluation of the unenhanced image set and the combined unenhanced/enhanced image sets. The final clinical diagnosis was provided by an independent truth committee following evaluation of findings from referral through a 3-month follow-up period, not including the study-specific MR image sets. Sensitivity = percentage of participants for which the imaging modality (unenhanced or Gadobutrol-enhanced) correctly detects malignant lesions as defined by the independent truth committee.
Time Frame	Up to 2 hours after injection of gadobutrol
Safety Issue	No

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
