The role of various radionuclide investigations, including parathyroid scintigraphy, bone scintigraphy and serum parathormone estimations in the diagnosis of primary hyperparathyroidism is reviewed briefly. The initial experience with the dual isotope (Tl-201; Tc-99m) subtraction scintigraphy for the preoperative localization of parathyroid adenomas is presented (JPMA 37 : 237, 1987).

Frostbite is a localized cold thermal injury that results from tissue freezing. Frostbite injuries can have a substantial effect on long-term limb function and mobility if not promptly evaluated and treated. Imaging plays a critical role in initial evaluation of frostbite injuries and in monitoring response to treatment. A multimodality approach involving radiography, digital subtraction angiog...

We undertook a retrospective study of 122 patients with ankle pain to determine the accuracy of bone scintigraphy using 99mTc-methylene diphosphonate (MDP) for detection of osteochondral talar dome fractures (OCTDF). Plain radiographs, which were available in 97 patients, had not revealed any abnormality in the talar dome. Bone scintigraphy was followed by CT, which was considered to be the ref...

A. Bone scintigraphy is a diagnostic study used to evaluate the distribution of active bone formation in the body. B. Whole-body bone scintigraphy produces planar images of the skeleton, including anterior and posterior views of the axial skeleton. Anterior and/or posterior views of the appendicular skeleton also are obtained. Additional views are obtained as needed. C. Limited bone scintigraph...

BACKGROUND This study compared the role and timing of bone scintigraphy and magnetic resonance imaging (MRI) in the evaluation of vertebral compression fractures (VCFs), before treatment with vertebroplasty and kyphoplasty. To our knowledge, no prior articles have described, in osteoporotic and pathological vertebral fractures, the role of MRI and bone scintigraphy as pre-procedural work up in ...

Diaphyseal medullary stenosis (DMS) is an extremely rare hereditary bone dysplasia, which was first described by Arnold in 1973. DMS has a high incidence of pleomorphic malignant fibrous histiocytoma (MFH). In this paper, we report the imaging findings of DMS with pleomorphic MFH of the bone, mainly describing 99mTc hydroxymethylenediphosphonate (HMDP) and thallium-201 (201Tl) chloride scintigr...

PURPOSE To compare the accuracies of computed tomography (CT), magnetic resonance (MR) imaging, and bone scintigraphy in staging disease in patients with neuroblastoma. MATERIALS AND METHODS Ninety-six children with newly diagnosed neuroblastoma were enrolled in a multicenter prospective cohort study. CT, MR, and bone scintigraphy were used to evaluate tumor stage. Sensitivity and specificity...

The objective of this work was to monitor the consolidation of the femur after osteosynthesis with a bridge plate associated with the intramedullary pin using scintigraphy. We used seven New Zealand breed male rabbits, at 4 months of age, with a mean weight of 3.5 kg. We performed a three-phase bone scintigraphy with technetium-labeled methylene diphosphonate (99mTc-MDP) before and after surger...

Background: The most frequent sites of metastases in prostatic carcinoma are bones. Bone scintigraphy is the diagnostic tool of first choice for staging bone metastases in cancer of the prostate. But this examination is expensive and time-consuming.Therefore we are looking especially for serum parameters like alkaline phosphatase, the isoenzyme of bone-specific alkaline phosphatase, and prostat...

The purpose of the present study was to analyze the effect of treatment of Paget's disease of bone (PDB) with bone scintigraphy using a computer-assisted diagnosis system (BONENAVI) that quantitatively evaluates bone metabolism. Seven patients with PDB (three male, four female; average age, 60 years; age range, 33-80 years) underwent bone scintigraphy and measurement of serum alkaline phosphata...
