Brief Summary
This phase II trial studies ferumoxytol in the magnetic resonance imaging of pediatric patients with brain tumors. Magnetic resonance imaging using ferumoxytol may help in viewing a brain tumor and blood vessels in and around the tumor in a different way than the standard gadolinium-based contrast agent. Imaging with this experimental contrast agent may give doctors more information about tumor blood supply and the extent of the tumor itself.

Outcome Measures
Primary Outcomes (4)
Overlay accuracy with 3-dimensional anatomical T1w post contrast scans
Ferumoxytol-based steady state-cerebral blood volume maps will be compared to gadolinium-based dynamic susceptibility weighted-cerebral blood volume maps using a 3-point scale. The mean score between the two readers will be used in the primary analyses. Inter-reader agreement will be assessed using weighted Kappa to make sure that the visualization variables are used reliably.
Up to 5 years
Confidence in identifying the lesion corresponding areas on cerebral blood volume maps
The mean score between the two readers will be used in the primary analyses. A linear mixed effects model will be used to compare the mean of the four visualization variables between steady state and dynamic susceptibility weighted overall and at each of time points while taking into account the correlation due to repeated measures within the same patient. Inter-reader agreement will be assessed using weighted Kappa to make sure that the visualization variables are used reliably.
Up to 5 years
Cerebral blood volume in small (< 1 cm) enhancing lesions
Ferumoxytol-based steady state-cerebral blood volume maps will be compared to gadolinium-based dynamic susceptibility weighted-cerebral blood volume maps using a 3-point scale.
Up to 5 years
Delineation of tumor from larger blood vessels
Ferumoxytol-based steady state-cerebral blood volume maps will be compared to gadolinium-based dynamic susceptibility weighted-cerebral blood volume maps using a 3-point scale. The mean score between the two readers will be used in the primary analyses. Inter-reader agreement will be assessed using weighted Kappa to make sure that the visualization variables are used reliably.

Study Arms (1)
Diagnostic (ferumoxytol, MRI)
EXPERIMENTALPatients undergo MRI with GBCA per standard of care over 45-60 minutes and then receive ferumoxytol IV followed by MRI over 10 minutes on day 1. Patients may optionally undergo MRI over 30 minutes without any contrast agent on day 2. Each study visit consisting of 2 days may repeat no more frequently than 4 weeks for up to 5 study visits at different stages of the disease as determined by the investigator.

Eligibility Criteria
You may qualify if:
- Subjects with a presumed diagnosis of brain tumor (based on imaging) or a confirmed brain tumor (based on pathology) before or after any oncologic treatment (surgery/chemotherapy/radiation)
- All subjects, or their legal guardians, must sign a written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization in accordance with institutional guidelines
- Subjects with a calculated glomerular filtration rate (GFR) \> 60 mL/min/1.73 m\^2
- Sexually active women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; surgical intervention i.e. tubal ligation or vasectomy; post-menopausal \> 6 months or abstinence) for at least two months after each cycle of the study; should a female become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
You may not qualify if:
- Subjects with clinically significant signs of uncal herniation, such as acute pupillary enlargement, rapidly developing motor changes (over hours), or rapidly decreasing level of consciousness, are not eligible
- Subjects with known allergic or hypersensitivity reactions to parenteral iron, parenteral dextran, parenteral iron-dextran, or parenteral iron-polysaccharide preparations (Ferumoxytol Investigator's Drug Brochure, 2009); subjects with significant drug or other allergies or autoimmune diseases may be enrolled at the investigator's discretion
- Subjects who are pregnant or lactating or who suspect they might be pregnant
- Subjects who have a contraindication for 3Tesla (3T) MRI: metal in their bodies (a cardiac pacemaker or other incompatible device), are severely agitated, or have an allergy to gadolinium containing contrast material
- Subjects with known iron overload (genetic hemochromatosis); in subjects with a family history of hemochromatosis, hemochromatosis must be ruled out prior to study entry with normal values of the following blood tests: transferrin saturation (TS) test and serum ferritin (SF) test; all associated costs will be paid by the study
- Subject who have received ferumoxytol within 4 weeks of study entry
