Table 2 Bland–Altman analysis comparing IDBC with SDBC

From: How to obtain the image-derived blood concentration from ⁸⁹Zr-immuno-PET scans

Blood pool region	Mean percentage bias (%)	1.96 Times standard deviation (%)
⁸⁹Zr-cetuximab
Aortic arch	− 24.7	25.1
Ascending aorta	− 10.9	20.3
Descending aorta	− 26.3	27.2
Left ventricle	− 20.8	30.8
⁸⁹Zr-durvalumab
Aortic arch	− 15.7	17.9
Ascending aorta	− 11.4	17.0
Descending aorta	− 14.2	24.2
Left ventricle	− 9.4	29.6

Bias and variability in IDBC compared with SDBC for both ⁸⁹Zr-mAbs and all four blood pool regions. The ascending aorta showed the best overall results in bias and variability
