Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

Nuclear medicine bone imaging has been the optimum diagnosis for the detection of bone disorders because the lesion could be detectable before the appearance of symptomatic and radiographic changes. Over the past three decades, (99m)Tc-MDP and (99m)Tc-HMDP have been used as bone scintigraphic agents because of their superior biodistribution characteristics, although they are far from optimal fr...

We present the domain-independent HRFF algorithm, which solves goal-oriented HMDPs by incrementally aggregating plans generated by the Metric-FF planner into a policy defined over discrete and continuous state variables. HRFF takes into account nonmonotonic state variables, and complex combinations of many discrete and continuous probability distributions. We introduce new data structures and a...

Purpose: To assess the role of 18F-NaF PET/CT in detection metastatic bone disease compared to 99mTc-MDP scan (+/-SPECT/CT). Methods: 64 adult patients with locally advanced primary tumor were enrolled this study. All underwent pretherapy and scan. Results: Among revealed positive metastases 26 patients, only 19 them have results scan, while remaining 7 falsely negative On other hand diagnosed ...
