Fig. 6From: Shortened duration whole body 18F-FDG PET Patlak imaging on the Biograph Vision Quadra PET/CT using a population-averaged input functionHealthy tissue Ki obtained using the IDIF compared with Ki obtained with the PIF scaled to the IDIF at scan time interval 30–60 min p.i. (PIF_30), 40–60 min p.i. (PIF_40), and 50–60 min p.i. (PIF_50). Mild outliers are marked with a circle and are data points that fall outside \({\text{quartile}}1\,\left( {Q1} \right) - 1.5*{\text{interquartile}}\,{\text{range}} \,\left( {{\text{IQR}}} \right)\) or \({\text{Q}}3 + 1.5 *{\text{ IQR}}\). Extreme outliers are marked with an asterisk and fall outside \({\text{Q}}1 - 3 *{\text{ IQR}}\) or \({\text{Q}}3 + 3 *{\text{ IQR}}\). For readability, axes were scaled differently for liver, spleen, and muscle Ki (a) with respect to grey matter Ki (b)Back to article page
