However, the sensitivity and accuracy of ⁹⁹mTc bone scintigraphy (planar) are improved near to those of ¹⁸F-fluoride PET/CT when SPECT is added to a planar scan. The sensitivity of ¹⁸F

Osteoblasts (bone-building cells) build up new bone substance much faster than is the case of a healthy bone. The radioactively labeled sodium fluoride (18F-fluoride) used in the fluoride-PET is incorporated into the bone matrix in the same way as phosphate and calcium, so that metabolically active areas of the bone can be made visible. Sodium fluoride PET has higher sensitivity and specificity in detecting and diagnosing bone diseases compared with conventional bone scintigraphy, even when the latter is supplemented with SPECT or SPECT/CT imaging 2. The primary clinical use of sodium fluoride PET is in detection of osseous prostate cancer metastasis.

Current risk-stratification tools for secondary prevention are limited to risk scores, coronary calcium scoring, and severity indices of obstructive CAD; 18 F-NaF Purpose: 18F-fluoride PET/CT exhibits high sensitivity to delineate and measure the extent of bone metastatic disease in patients with prostate cancer. 18F-fluoride PET/CT could potentially replace traditional bone scintigraphy in clinical routine and trials. However, more studies are needed to assess repeatability and biological uptake variation. Intense FDG uptake by bone marrow following recent chemotherapy limits evaluation for osseous metastases.

This study evaluated the diagnostic impact of using skeletal (18)F-fluoride PET/CT on patients with painful bone metastases to schedule an early palliative radionuclide treatment. The skeletal involvement from prostate cancer metastases was assessed

The arms may be by the sides for whole-body imaging or elevated when only the axial skeleton is scanned. 2. Protocol for CT imaging See the SNM Procedure Guideline for Tumor Imaging with 18F-FDG PET/CT. CT may be performed for attenuation correction On the patient basis, the pooled sensitivity and specificity of 18 F-fluoride PET/CT were 93% (95% confidence interval [CI], 91-96%) and 95% (95% CI, 93-96%) when equivocal results were considered as negative for BM; and 96% (95% CI, 93-97%) and 93% (95% CI, 91-95%) when equivocal results were considered as positive. Compared with 18 F-NaF PET/CT, 18 F-DCFBC PET/CT detected significantly fewer bone lesions in the setting of early or metastatic castrate-sensitive disease on treatment. However, in advanced metastatic castrate-resistant prostate cancer, 18 F-DCFBC PET/CT shows good concordance with NaF PET/CT.
