OTS in the meninges is related to target regions
After quantifying OTS across several meningeal ROIs, we wanted to demonstrate spill-in that occurs between OTS ROIs and target regions. To explore this, we first created groups based on OTS SUVR tertiles in each OTS ROI and then plotted target ROI SUVRs by the corresponding OTS tertiles. Using our standard MRI-guided processing, we observed that target region and reference region SUVRs track with adjacent OTS tertiles (
