Nuclear medicine - Thalium scan
30 minutues
4 hours
RADIOPHARMACEUTICAL: 201Tl, 160 MBq
Hemi-body sweeps of the lower half of the body were performed 0.5 and 4 hours following MIBI infusion, these studies were compared to the piror bone scan. The current studies show increased Thallium uptake diffusely in the left tibial shaft and to a lesser extent in the left femoral shaft consistent with the changes seen in the bone scan. Tibial and femoral uptake in the early studies is higher than in the later ones.
Conclusion: Overall impression is that no focus suspicious of malignancy is detected. A diffuse premalignant or malignant change is not totally excluded but is not likely. About one-half of fibrous dysplasias show Thallium uptake.
