Brief Summary: This clinical trial studies magnetic resonance imaging (MRI) using a contrast imaging agent ferumoxytol (ferumoxytol non-stoichiometric magnetite) in improving viewing tumors in patients with high-grade brain tumors or cancer that has spread to the brain. Diagnostic procedures, such as MRI, may help find and diagnose brain tumors and find out how far the disease has spread. The contrast imaging agent ferumoxytol non-stoichiometric magnetite consists of small iron particles taken by the blood stream to the brain and to the area of the tumor. It may help visualize the blood flow going through the tumor better than the standard substance gadolinium-based contrast agent.

Detailed Description: PRIMARY OBJECTIVES:

I. Investigate the utility of ferumoxytol and gadolinium-based contrast agent (GBCA) for improved imaging biomarkers of malignant brain tumors in a single imaging session by comparing dynamic susceptibility contrast (DSC) determined relative cerebral blood volume (rCBV) and dynamic contrast enhancement (DCE) determined vascular permeability (derived transfer coefficient \[Ktrans\]).

SECONDARY OBJECTIVES:

I. Compare and evaluate magnetic resonance angiography (MRA) with ferumoxytol between different time points.

II. Assess number and size of tumors imaged. III. Assess tumor vascularity. IV. Assess histology and electron microscopy (EM) on tissue samples. V. Assess differences in subjects with prior therapy versus (vs.) no prior therapy (radiation and/or chemotherapy).

VI. Assess the long term imaging characteristics of different tumors using DSC and DCE.

OUTLINE:

Patients receive ferumoxytol non-stoichiometric magnetite intravenously (IV) beginning approximately 15 seconds after start of 3T DSC-MRI and GBCA IV approximately 1 minute and 50 seconds after start of 3T DCE-MRI on day 1. Patients also undergo MRI without contrast at baseline and on day 2. Imaging with ferumoxytol, GBCA, and without contrast repeats every 3 weeks for a total of 6 more imaging sessions over up to 5 years.

After completion of study, patients are followed up at approximately 4-6 weeks.

Primary Outcome Measures

Name	Time	Method
Utility of Ferumoxytol and Gadolinium Based Contrast Agents for Improved Imaging Biomarkers of Malignant Brain Tumors in a Single Imaging Session by Comparing Dynamic Susceptibility Contrast (DSC) Determined Relative Cerebral Blood Volume (rCBV) Maps.	Summarized after completion of up to 6 imaging sessions (up to 5 years)	Compare rCBV measurements in regions of interest obtained from ferumoxytol DSC-MRI with gadolinium based contrast agent (GBCA) MR images to evaluate vascular properties of brain tumors. CBV maps were generated by applying tracer kinetic model to the first pass of the contrast bolus. Voxelwise CBV maps were coregistered to T1 weighted images and then normalized by dividing by the mean of normal appearing white matter CBV in the same region in the contralateral hemisphere. RCBV values (as the area under the signal intensity curve, normalized by the area under the curve for the control region) were obtained. Values range from 0 (low intensity) to 180 (highest intensity).
Utility of Femumoxytol and Gadolinium Based Contrast Agents for Improved Imaging Biomarkers of Malignant Brain Tumors in a Single Session by Comparing Dynamic Contrast Enhanced Determined Vascular Permeability (Ktrans)	Assessed after each visit for up to 6 imaging sessions (up to 5 years)	Appropriate descriptive statistics (mean, standard deviation, minimum, median, and maximum) will be estimated for the imaging parameters Ktrans. Frequency distributions of each parameter will also be described to assess normality. Pearson's correlation coefficients will be estimated to describe potential relationships among these various measures.

Secondary Outcome Measures

Name	Time	Method
Compare Number and Size of Tumors Imaged With Ferumoxytol and Gadolinium Based Contrast Agents (Cube Root Volume)	Summarized after completion of up to 6 imaging sessions (up to 5 years)	We analyzed 193 sets of post-gadoteriol and 24 hours post-ferumoxytol T1 weighted scans from 58 patient with high grade glioma. Enhancement volumes normalized to normal appearing white matter were calculated with histogram analysis. Enhancement cube root volumes were compared between the two contrast agents. Ferumoxytol and gadolinium enhanced MR images were obtained from each participant.
Compare Number and Size of Tumors Imaged With Ferumoxytol and Gadolinium Based Contrast Agents (Signal Intensity)	Summarized after completion of up to 6 imaging sessions (up to 5 years)	We analyzed 193 sets of post-gadoteriol and 24 hours post-ferumoxytol T1 weighted scans from 58 patient with high grade glioma. Signal intensities normalized to normal appearing white matter were calculated with histogram analysis. Signal intensities were compared between the two contrast agents. Ferumoxytol and gadolinium enhanced MR images were obtained from each participant. Signal intensities were normalized to the signal intensity value of non-enhancing voxels inside the manual ROI (the relative complement of the final mask in Q, i.e. Q \\ \[A ∩ B ∩ C\]). Higher values in signal intensity indicated increased image enhancement.
Overall Survival in Participants With Pseudoprogression With or Real Tumor Progression Using Ferumoxytol Enchanced Perfusion MRI	Assessed after each visit for up to 6 imaging sessions (up to 5 years)	We evaluated overall survival in patients with pseudopregression or real tumor progression by using relative cerebral blood volume values on ferumoxytol enhanced perfusion MRIs.
