Participants will undergo DCE and DSC-MRI imaging at the following time points:
- no more than 3 weeks prior to MLA (OPTIONAL)
- within approximately 4 days after MLA
- 2-4 weeks after MLA
- Every 12 weeks (+/- 7 days) for the first year or until disease progression

Elevated serum NSE seemed to correlates with disruption in BBB following MLA and transient increase in BBB permeability.

| Secondary | Correlation of MR Imaging With Peritumoral BBB Disruption | The linear regression model will used to investigate the correlation between MR imaging and peritumoral BBB disruption. To account for correlation among the repeated measures from the same patient, the longitudinal data will be analyzed with the use of linear generalized estimating equation (GEE). Whether the average measurements differ at the multiple time points will be evaluated through GEE model. Least-square means at each time points will be presented and standard errors will be calculated within the use of the GEE sandwich method when accounting for within-patient correlation. | Data was not collected for this outcome measure. | Posted | | | | | | 1 year from MLA | | | | ID | Title | Description |
