Accuracy of whole-body fluorine-18-FDG PET for the detection of recurrent or metastatic breast carcinoma.

Abstract

The whole-body FDG-PET scan is a useful diagnostic test for detecting recurrent or metastatic lesions of breast carcinoma. However, the sensitivity for metastases to bone appears to be lower than that to other organs. Specificity may be improved by more strict attention to patient preparation and better recognition of physiologic skeletal muscle or artifactual uptakes.
