INTRODUCTION Two-stage revision arthroplasty is today considered as the gold standard for control of chronic deep prosthetic infection. Although the revision arthroplasty should only be considered when infection is eliminated, the diagnosis of residual infection prior to the revision remains a challenging problem. MATERIALS AND METHODS We evaluated triple-phase bone scintigraphy as a useful d...

OBJECTIVE To review short term results of uncemented cup implantation and the fate of bulk femoral head autografts in patients with acetabular bone deficiency due to dysplasia of the hip. We used bone scintigraphy to assess the viability of the grafts. METHODS We treated 19 hip joints of 17 patients with osteoarthritis due to developmental dysplasia of the hip with uncemented total hip arthro...

UNLABELLED Endovenous bisphosphonate therapy seems associated with osteonecrosis of the jaw. The aim of this study was to evaluate the additional diagnostic value of hybrid SPECT/CT in 99mTc-methylene diphosphonate 3-phase bone scintigraphy of osteonecrosis of the jaw in bisphosphonate-treated patients. METHODS We studied 15 patients (12 women and 3 men) with extraoral tumors affected by lyti...

UNLABELLED Distraction osteogenesis is an effective method for lengthening long bones and filling bone defects that result from bone resection. Insufficiency of bone consolidation in the distraction segment is problematic. In this study, we examined whether 3-phase bone scintigraphy can predict the outcome of distraction osteogenesis. We also investigated the effects of chemotherapy and surgica...

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...

metastatic survey of the patients with known primary malignancies with bone scan is one of the most common studies in nuclear medicine. unfortunately the conventional planar bone scan has a very low specificity for differentiating benign from malignant lesions especially in the spinal column. in this study, we compared the specificity of spect imaging and conventional planar bone scan. we studi...

OBJECTIVE This study aimed to present seven cases of avascular necrosis of the sesamoid and report the role of bone scintigraphy in the diagnosis of these patients. METHODS Seven patients with clinical suspicion of avascular necrosis of the sesamoid underwent three-phase bone scintigraphy with 30 mCi of (99m)Tc-MDP. RESULTS Most of the patients were young female adults with complaints of li...

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.

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 ...
