Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

Bone mineral content (BMC) and bone mineral density (BMD) measurements were made by dual-energy x-ray absorptiometry (DEXA) in 112 healthy 12-yr-old white girls for the purposes of: (1) establishing reference data on total-body mineral content of 12-yr-old girls and (2) comparing the lumbar spinal bone density values from a dedicated scan with the lumbar region of interest bone density values f...

Various models of the human chest have been developed to evaluate injury risks or to assess innovative safety systems. In the frame of the EU FP7 project THOMO, a protocol has been established to determine relevant parameters of the human ribcage. This original method has been developed by combining CT-scan, 3D laser scan and μCT-scan to determine precisely the internal rib architecture. The ma...

METHODS Between November 2005 and July 2006, 317 men with prostate cancer underwent a bone scan study; 176 men fulfilled the inclusion criteria. Prostate-specific antigen (PSA) cut-offs as well as univariate and multivariate logistic regression analyses using digital rectal exam...

Cemento-ossifying fibroma is a rare benign fibro-osseous neoplasm commonly involving the jaws majority of lesions occur in mandible bone. It can be discovered as an incidental finding radiological imaging. Symptomatic patients are presented with slowly growing mass bone and attain large size passage time. cause facial deformity if left untreated. We present such case right hemi-mandible bone, i...

PURPOSE To develop a nomogram predictive of current bone scan positivity in patients receiving androgen-deprivation therapy (ADT) for advanced prostate cancer; to augment clinical judgment and highlight patients in need of additional imaging investigations. MATERIALS AND METHODS A retrospective chart review of bone scan records (conventional (99m)Tc-scintigraphy) of 1,293 patients who receive...
