What was measured
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.
Analysis population: 58 participants had both appropriate ferumoxytol and gadolinium scans available for analysis for this outcome.
Groups in this outcome
Malignant Brain Tumor Patients Undergoing Brain MRI- Gadolinium-enhanced MRI
Study patients: adult patients with high grade primary malignant brain tumors or with known or suspected brain metastases from histologically confirmed primary cancer Study procedures: patients will receive IV ferumoxytol (maximum dose 4 mg/kg, over at least 15 minutes) 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 will also undergo MRI without contrast at baseline (before 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. 3 Tesla Magnetic Resonance Imaging: Undergo 3T MRI Dynamic Contrast-Enhanced Magnetic Resonance Imaging: Undergo 3T DCE-MRI Dynamic Susceptibility Contrast-Enhanced Magnetic Resonance Imaging: Undergo 3T DSC-MRI Ferumoxytol: Given IV Gadolinium: Given IV MRI-Based Angiogram: Undergo MRA
