From: Early-phase 18F-FP-CIT and 18F-flutemetamol PET were significantly correlated

The SUVR time-activity curves (TACs) fitted using the simplified reference tissue method (SRTM) obtained from early-phase 18F-FP-CIT (A) and 18F-flutemetamol PET (B) images. The SUVR of 18F-FP-CIT in the central structure rose relatively steeply compared to other brain regions after 9 min (blue connecting line in A). Error bars represent the interquartile range of the median. Typical example of SUVR TACs using SRTM fitting in a patient (C,D).
