Purpose: We evaluated the feasibility of (18)Fluoride Positron Emissio
n Tomography (F-18-PET), investigated the characteristic appearance of
bony structures, and compared the quality of F-18-PET images with con
ventional bone scans (BS). Method: F-18-PET scans were performed in 59
patients additional to conventional bone scintigraphy. Results: Even
very small details in the spine like the spinous and transverse proces
ses were clearly visible with F-18-PET. Only half of these structures
were visualised with BS. When visualising the vertebral bodies of the
first rib from the clavicles and the twelfth rib from the kidneys, we
arrived at similar results. Hot spots in the skull or at the manubrios
ternal joint were observed in 29% of the patients without any evidence
of trauma, degeneration or metastasis. Conclusion: F-18-PET shows mor
e details of the skeleton compared to BS. Some hot spots not occurring
with BS must be regarded as physiological.
