Brief Summary
This phase II trial studies how well magnetic resonance imaging (MRI) using contrast imaging agent ferumoxytol works in comparison to standard imaging agent gadolinium in measuring tumors in patients undergoing treatment for brain tumors or other tumors that have spread to the brain. Diagnostic procedures, such as MRI, may help find and diagnose disease and find out how far the disease has spread. MRI scans use radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. The contrast imaging agent ferumoxytol consists of small iron particles taken by the blood stream to the brain and to the area of the tumor. It is highly visible on the MRI, and may help visualize the blood flow going through the tumor better than gadolinium can. Using a more sensitive and faster 7 Tesla (7T) magnet MRI in conjunction with a contrast imaging agent may provide a better way to measure tumors than the 3 Tesla (3T) magnet MRI in patients with brain tumors.

Outcome Measures
Primary Outcomes (2)
Contrast to Noise Ratio (CNR), in Terms of Normalized Signal Intensity Changes, for T1-weighted MRI Signal at 3T and 7T (Gadolinium [Gd] T1-weighted Magnetic Resonance Imaging [MRI] DCE Data Only)
Paired sample t-tests will be used for primary descriptive comparisons. Secondary analyses will use a repeated measures analysis of variance (ANOVA) model to compare 3T and 7T while adjusting for other factors including tumor type, prior therapy, and, potentially, important baseline factors that differ between the subjects assigned to the two field strengths. Normality will be assessed graphically and, if needed, a transformation (e.g. the logarithmic transform) will be applied.
Baseline to day 1
CNR, in Terms of Normalized Signal Intensity Changes, for Dynamic Susceptibility Contrast (DSC) MRI Data Sets at 3T and 7T (Gadolinium and Ferumoxytol)
A two sample t-test was used for primary descriptive comparisons since CNR was measured on different subjects at 3T and 7T. There were no repeated measures in the resulting data. Given the small sample size, a linear regression was conducted to compare CNR between 3T and 7T only adjusted for Fe dose. No other adjusted analyses were conducted. CNR was compared between 3T and 7T for both Ferumoxytol and Gadolinum. Ferumoxytol was administered using three injections and CNR was measured after each injection, thus we have three measures of CNR (Fe1CNR, Fe2CNR and Fe3CNR).

Study Arms (1)
Diagnostic (Gd, ferumoxytol, 3T or 7T MRI)
EXPERIMENTALPatients receive gadolinium IV on day 1 and ferumoxytol non-stoichiometric magnetite IV on day 2. Patients undergo anatomical MRI sequences with 3T or 7T at baseline and on days 1-3. Patients also undergo DSC MRI and DCE MRI on days 1-2. Day 1 and day 2 imaging sessions may be separated by up to 7 days.

- Subjects with known hepatic insufficiency or cirrhosis
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to ferumoxytol
- Subjects with known or suspected iron overload (genetic hemochromatosis or history of multiple transfusions)
- Uncontrolled concurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
