This randomized pilot clinical trial studies quantitative susceptibility mapping (QSM) and regional dynamic contrast enhanced (DCE) magnetic resonance imaging (MRI) permeability using golden-angle cartesian randomized time-resolved (GOCART) technique in evaluating regional gadolinium retention in the brain in patients with intracranial neoplasm receiving gadobenate dimeglumine or gadoterate meglumine. MRI diagnostic techniques such as, QSM and DCE MRI, may help to gather information regarding brain changes associated with gadolinium deposits during 8 to 18 months after administration of gadobenate dimeglumine or gadoterate meglumine.
PRIMARY OBJECTIVES: I. To obtain preliminary data (e.g. mean, variance, distribution) in the regional brain parenchymal changes associated with gadolinium (Gd) deposition during 8 to 18 months period after administration of gadolinium based contrast agents (GBCA) to Gd naive intracranial neoplasm patients who will be randomized to gadobenate dimeglumine (MultiHance) or gadoterate meglumine (Dotarem). II. To explore if areas of increased regional Gd deposition at individual level are correlated with baseline regional DCE permeability metrics such as volume transfer coefficient reflecting vascular permeability (kTrans), extracellular volume ratio reflecting vascular permeability (ve) and plasma volume (vp) in intracranial neoplasm patients. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients undergo standard of care QSM and T1 weighted imaging (T1WI). Patients then receive gadobenate dimeglumine intravenously (IV) and undergo GOCART DCE MRI over 60 minutes. ARM II: Patients undergo standard of care QSM and T1WI. Patients then receive gadoterate meglumine IV and undergo GOCART DCE MRI over 60 minutes. After completion of study, patients are followed up at 8-18 months.

Change in QSM score
Descriptive statistics will be used to describe the magnitude of Gd deposition measured by QSM score in each of the two study groups. Histograms will be generated for QSM score at each time point as well as the change from the baseline for each group. The descriptive statistics will be used to calculate the mean, median, interquartile range, and standard deviation. Box plot and overlying histogram will be used to illustrate the distribution of change in Gd deposition between gadobenate dimeglumine and gadoterate meglumine group. Correlation between QSM score versus (vs.) kTrans and QSM score v
Time frame: Baseline up to 18 months
Change in T1WI signal intensity ratio
Descriptive statistics will be used to describe the magnitude of Gd deposition measured by T1WI signal intensity ratio in each of the two study groups. Histograms will be generated for T1WI signal intensity ratio score at each time point as well as the change from the baseline for each group. The descriptive statistics will be used to calculate the mean, median, interquartile range, and standard deviation. Box plot and overlying histogram will be used to illustrate the distribution of change in Gd deposition between gadobenate dimeglumine and gadoterate meglumine group. Correlation between T1W
Time frame: Baseline up to 18 months
kTrans and Ve signal using GOCART 3D MRI
The signal (kTrans and Ve) will be obtained in voxel level then taking average within the region of interest (ROI). ROI will be placed on the pons, bilateral globi pallidi, thalami and dentate nuclei to obtain the average signal within the ROI. Averages of all bilateral measurements will be used to calculate the final signal for kTrans and Ve. The final kTrans and Ve signal will only be used to assess the correlation with QSM and T1WI signal intensity ratios.
Time frame: Up to 18 months
