Table 2 Comparison among PM and both 3D dosimetry methods (LDM and DPK) in terms of mean absorbed dose delivered to target and whole normal liver: Bland Altman analysis, Pearson’s correlation, and Lin concordance coefficients

From: Impact of the dosimetry approach on the resulting 90Y radioembolization planned absorbed doses based on 99mTc-MAA SPECT-CT: is there agreement between dosimetry methods?
