Notes

Acknowledgments

We thank Dr. Høilund-Carlsen and Dr. Alavi for their interest in our article [1]. The authors wrote that the combined Na[18F]F/[18F]FDG PET/MRI approach used in our study can be an overkill causing more confusion than clarity [2]. The reason for this confusion seems to be the high sensitivity of Na[18F]F, which may identify cancer-like foci in case of microcalcification caused by other conditions than malignancy. The authors reference two case reports to support their argument [3, 4]; Na[18F]F uptake was described in both of their cases in noncancerous calcifications of the tracheobronchial tree and of a uterine leiomyoma, respectively.
