Fig. 5

Bland–Altman plot of tumour absorbed doses estimated from ⁶⁸Ga-PET images and ¹⁷⁷Lu SPECT. Quantification of the mean deviation (solid line) and the 95% coverage interval (dashed lines) was based on the average tumour absorbed doses for each patient (filled markers). The agreement for individual tumours is also indicated (open markers). The relative difference refers to the absorbed dose estimated from ⁶⁸Ga-PET over the absorbed dose estimated through peri-therapeutic imaging
