abstract = {PurposeDynamic 60-min positron emission tomography (PET)
imaging with the novel tau radiotracer [18F]PI-2620
facilitated accurate discrimination between patients with
progressive supranuclear palsy (PSP) and healthy controls
(HCs). This study investigated if truncated acquisition and
static time windows can be used for [18F]PI-2620 tau-PET
imaging of PSP.MethodsThirty-seven patients with PSP
Richardson syndrome (PSP-RS) were evaluated together with
ten HCs. [18F]PI-2620 PET was performed by a dynamic 60-min
scan. Distribution volume ratios (DVRs) were calculated
using full and truncated scan durations (0–60, 0–50,
0–40, 0–30, and 0–20 min p.i.). Standardized uptake
value ratios (SUVrs) were obtained 20–40, 30–50, and
40–60 min p.i.. All DVR and SUVr data were compared with
regard to their potential to discriminate patients with
PSP-RS from HCs in predefined subcortical and cortical
target regions (effect size, area under the curve (AUC),
multi-region classifier).Results0–50 and 0–40 DVR showed
equivalent effect sizes as 0–60 DVR (averaged Cohen’s d:
1.22 and 1.16 vs. 1.26), whereas the performance dropped for
0–30 or 0–20 DVR. The 20–40 SUVr indicated the best
performance of all static acquisition windows (averaged
Cohen’s d: 0.99). The globus pallidus internus
discriminated patients with PSP-RS and HCs at a similarly
high level for 0–60 DVR (AUC: 0.96), 0–40 DVR (AUC:
0.96), and 20–40 SUVr (AUC: 0.94). The multi-region
classifier sensitivity of these time windows was
consistently $86\%.ConclusionTruncated$ and static imaging
windows can be used for [18F]PI-2620 PET imaging of PSP.
0–40 min dynamic scanning offers the best balance between
accuracy and economic scanning.},
