Introduction: The purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  Methods: A total number of forty eight adult, male NMRI rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. Each part has been divided into four groups, one group not receivi...

introduction: the purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (mdp) with the estimates given in mirdose software. methods: in this study, each patient was injected 25 mci of 99m tc-mdp. whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minute...

An enostosis or bone island is a benign bony lesion that is almost diagnosed based on clinical and radiologic defining characteristics. One of the known diagnostic procedures in the evaluation of enostosis is bone scintigraphy. Generally, we don’t expect to see increased uptake by enostosis in the bone scan. Herein we present a 52-year-old lady who was suffering from chronic low back pain that ...

sternal non-:union: is a severe complication of sternotomy closure following open heart surgeries. healing problems typically occur in 0.3% to 5% of patients. technetium-99m methylene diphosphonate (99mtc-mdp) bone scintigraphy has been used to assess bone non:union: to predict the healing response for proper management.  in this report, we present the case of a marked sternal non:union: follow...

sternal non-union is a severe complication of sternotomy closure following open heart surgeries. healing problems typically occur in 0.3% to 5% of patients. technetium-99m methylene diphosphonate (99mtc-mdp) bone scintigraphy has been used to assess bone nonunion to predict the healing response for proper management.  in this report, we present the case of a marked sternal nonunion following...

The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...

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...

  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 complain...

BACKGROUND Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete. OBJECTIVES To evaluate whether the one-legged hyperextension test can assist in the clinical detection of active spondylolysis and to determine whether magnetic resonance imaging (MRI) is equivalent to the clinical gold standard of bone scintigraphy a...

The present case demonstrates a diffuse intense hepatic and, to a lesser degree, spleen, Tc-99m MDP uptake on a routine bone scintigraphy resembling liver-spleen imaging. A 49-year-old female with a history of anaplastic plasma cell tumor and suffering from bone pain was referred for bone scintigraphy to evaluate possible bone metastases. The bone scintigraphy showed diffuse hepatic and spleen ...
