Bone involvement has been reported in 1-13% of patients with sarcoidosis. Both 18F-fluorodeoxyglucose ((18)F-FDG) Positron Emission Tomography/Computed Tomography (PET/CT) and conventional magnetic resonance imaging (MRI) are sensitive in detecting sarcoidosis bone lesions, but are not always reliable in differentiating sarcoidosis bone lesions from metastatic disease, thus often requiring bone...
BACKGROUND AND AIM: Giant cell lesions as a group of the oral and maxillofacial lesions are common and potentially destructive. The aim of this study was to assess the frequency of oral lesions containing giant cells in a 22-year period in Isfahan Dental School, Iran.METHODS: In this epidemiological, cross-sectional, retrospective study the archive information in the Department of Oral Patholog...
Existing clinical imaging procedures lack sensitivity and specificity in detecting early prostate cancer bone metastatic lesions. In this study, we developed a highly reproducible bone metastasis xenograft model and identified possible molecular imaging candidates for detecting early bone metastatic lesions. Bone trophic human prostate cells (PC-3B1) were isolated and characterized for their ab...
POEMS syndrome is a rare plasmacyte-associated disease, one of the major diagnostic criteria of which is sclerotic bone lesion. To detect bone lesions in POEMS syndrome, which imaging method should be routinely applied and what characteristics they display are still unconfirmed. We analyzed clinical data and imaging characteristics of bone lesions in 22 patients with POEMS using multimodal meth...
There are various modalities of joint imaging e.g. conventional radiography (CR), computed tomography (CT), magnetic resonance imaging (MRI), bone scintigraphy, positron emission tomography (PET), ultrasonography (US), bone densitography. CR shows only bone lesions, while CT demonstrate both bone and soft-tissue changes. MRI is the best modality at showing soft tissue contrast than CT scan and ...
We compared MRI, CT and bone scintigraphy in the examination of experimentally produced metastatic bone tumors. Three Japanese white rabbits with VX-2 bone tumor were used. T1 weighted (T1W) and T2 weighted (T2W) images were obtained in each MRI examination. All the tumors distributed from the bone marrow to the extraosseous region. T2W images were the best to detect the extraosseous tumors. CT...
