Erratum: “Factors modulating ^99mTc‐MAA planar lung dosimetry for ⁹⁰Y radioembolization”

Lopez, BP, Mahvash, A, Long, JP, Lam, MGEH, Kappadath, SC. Factors modulating ^99mTc‐MAA planar lung dosimetry for ⁹⁰Y radioembolization. J Appl Clin Med Phys. 2022;23:e13734.

In Materials and Methods Section 2.2 | ^99mTc‐MAA SPECT/CT dosimetry (Page 3 of 11), the following text and equation in Paragraph 3 was incorrectly stated:

$LS{F}^{spect}$ was calculated as the ratio of the estimated total lung counts ($C_{LR}^{spect}$) to the estimated total liver counts (Equation 2).

$$LS{F}^{spect}=\frac{C_{LR}^{spect}}{C_H^{spect}}$$ (2)

The correct text and equation describing the SPECT/CT‐based lung shunt fraction ($LS{F}^{spect}$) calculation should be:

$LS{F}^{spect}$ was calculated as the ratio of the estimated total lung counts ($C_{LR}^{spect}$) to the sum of the estimated total lung counts ($C_{LR}^{spect}$) and total liver counts ($C_H^{spect}$) (Equation 2).

$$LS{F}^{spect}=\frac{C_{LR}^{spect}}{C_{LR}^{spect}+C_H^{spect}}$$ (2)

We have verified that the data analysis was based on the correct equation stated above. The published results and conclusions of the paper are valid. We apologize for this error.
