Article Figures & Data
Figures
- FIGURE 1.
The 12 ROIs standardized using 3DSRT: callosomarginal, precentral, central, parietal, angular, temporal, posterior cerebral, pericallosal, lenticular nuclear, thalamic, hippocampal, and cerebellar.
- FIGURE 2.
Flowchart for Patlak-plot, BUR-C, and BUR-AS methods. Patlak and BUR-C include manual processing. BUR-AS includes manual processing for aortic ROI and time–activity curve range and automatic processing for basal ganglia ROI and slice selection. mCBF and mSPECT = mean CBF and SPECT counts, respectively; TAC = time–activity curve.
- FIGURE 3.
CVs for interoperator reproducibility. CV is significantly lowest for BUR-AS.
- FIGURE 4.
Bland–Altman plots for interoperator reproducibility. Difference is lowest for BUR-AS.
- FIGURE 5.
Examples of ROI setting and γ fitting by the 3 radiologic technologists (RT1, RT2, and RT3). At top are the dynamic image slices and the chosen ROI; at bottom are graphs of time–activity curves.
- FIGURE 6.
CVs for intraoperator reproducibility for the 3 radiologic technologists (RT1, RT2, and RT3). CV was lowest for BUR-AS; CV for BUR-C for RT2 and Patlak plot for RT3 did not significantly differ.
- FIGURE 7.
Bland–Altman plots for intraoperator reproducibility. Difference is lowest for BUR-AS.
