The value of 18F-FDG PET/CT in the assessment of cardiac malignancy remains to be defined: Reply

摘要

We thank Drs. Cheng and Alavi for adding and corroborating interesting points of discussion. We completely agree with the authors that the sensitivity and specificity of ~(18)F-FDG PET would be much lower in patients without a prior diagnosis of a cardiac tumor by morphologic imaging. Our results are restricted to patients with known cardiac tumors. ~(18)F-FDG PET is certainly not going to be the first-line procedure for excluding cardiac involvement in patients with known or suspected malignancy elsewhere.
