this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

Focal tracer uptake in the jaw during conventional bone scintigraphy is a quite frequent finding usually due to dental disease and seldom to other diseases including malignant disease. Methylene diphosphonate-technetium-99m ((99m)Tc-MDP) 3-phase bone scan is considered the most sensitive imaging method for the detection of jaw osteonecrosis at an early stage. This finding can also but seldom be...

introduction: almost all malignant tumors have the potential to eventually produce bone metastasis. the aim of the current study was to report the distribution pattern and imaging characteristics of bone metastases detected by conventional whole body bone scintigraphy in patients with different types of malignancies and to assess their relationship with the complaint of bone pain. methods: as ...

PURPOSE OF THE STUDY The aim of the study was to demonstrate, by three-phase bone scintigraphy, radionuclide uptake at the site of defects in long bones filled with the non-resorbable bioactive glass-ceramic material BAS-0 at a long follow-up. MATERIAL Twenty patients, 14 men and 6 women, operated on between 1990 and 2000 for benign bone tumors or tumor-like lesions localized in the femur, ti...

objective(s): bonenavi, a computer-aided diagnostic system, is used in bone scintigraphy. this system provides the artificial neural network (ann) and bone scan index (bsi) values. ann is associated with the possibility of bone metastasis, while bsi is related to the amount of bone metastasis. the degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. therefore, t...

OBJECTIVE To evaluate the use of radionuclide bone scintigraphy following biochemical recurrence after radical retropubic prostatectomy (RRP) for localized prostate cancer. PATIENTS AND METHODS Of 1197 patients undergoing RRP we identified those with biochemical recurrence and who had also had a bone scan. Biochemical recurrence was defined as a prostate specific antigen (PSA) level of > or =...

A 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. In the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. However, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...

UNLABELLED The purpose of this study was to describe the clinical presentation of bone metastases in patients with carcinoid tumors and to determine the diagnostic value of imaging techniques and markers of bone metabolism. METHODS This retrospective study was performed on the entire group of patients with carcinoid tumors treated in our hospital from January 1992 to May 1999. Only patients w...
