PRIMARY outcome

Timeframe: Assessed after each visit for up to 6 imaging sessions (up to 5 years)

Population: Software to derive K trans values from acquired images is not available and enhancement comparison between gadolinium and ferumoxytol K trans values is not possible to date.

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.

PRIMARY outcome

Timeframe: 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).

SECONDARY outcome

Timeframe: Summarized after completion of up to 6 imaging sessions (up to 5 years)

Population: 58 participants had both appropriate ferumoxytol and gadolinium scans available for analysis for this outcome.

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.

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.
