Errata

In the article “MIRD Pamphlet No. 25: MIRDcell V2.0 Software Tool for Dosimetric Analysis of Biologic Response of Multicellular Populations” (J Nucl Med. 2014;55:1557–1564), the methods incorrectly state that the 2-D and 3-D cell geometries are close-packed square lattice and close-packed cubic lattice, respectively. Rather, they are simple square lattice and simple cubic lattice, respectively. The authors regret the incorrect statement.

In the article “Borderline Findings in O-(2-[¹⁸F]-Fluoroethyl)-l-Tyrosine PET of Patients with Suspected Glioma Relapse: Role in Clinical Practice” (J Nucl Med. 2025;66:187–193), a systematic error in calculations, leading to an overestimation of sensitivity and negative predictive values in Table 2 and Supplemental Tables 2 and 3, was discovered. Revised Table 2 is provided below, and revised Supplemental Tables 2 and 3 are provided in the supplemental materials of the original article. In addition, in the abstract on page 187, final diagnoses of tumor relapse were confirmed by histopathology in 263 [not 175] patients and by clinical course in 176 [not 264] patients. On page 191 in the Discussion, the diagnostic performance showed a lower sensitivity (69%–73%) and a lower specificity (67%–70%) [not a higher sensitivity (94%–95%) but a lower specificity (67%–70%)]. The authors regret the errors.
