Breast Cancer 02
Metastatic Bone Disease Case Study 02
42-year-old female patient with breast carcinoma was referred for evaluation of possible skeletal metastases by sodium fluoride F 18 (18F NaF) bone PET/CT imaging.
NUCLEAR MEDICINE 18F NaF BONE PET/CT SCAN
STATED REASON FOR REQUEST: Staging breast cancer
RADIOPHARMACEUTICAL ADMINISTERED: 18F NaF
TECHNIQUE: A whole-body PET/CT study was performed approximately one hour after intravenous administration of 18F NaF.
Normal distribution of the tracer was visualized throughout the entire skeletal system, except for mild degenerative changes in the lower lumbar vertebrae (arrows). There was no evidence of skeletal metastatic disease.
The 18F NaF bone PET study is more sensitive than bone scanning using gamma camera systems for detecting osseous lesions for several cancers like breast and prostate.1 It can be used as an alternative to bone scanning. The improved image quality, cross sectional visualization and CT correlation available with the PET/CT bone study further enhance diagnostic confidence for characterization of skeletal lesions, especially differentiation of benign from malignant.
