Table 5 Bland Altman analysis, Pearson’s correlation, and Lin concordance coefficients, of mean absorbed doses delivered to both tumoral liver and individual tumors volumes among the studied dosimetry methods (PM, MTPM, LDM, and DPK)

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?
