Generalized high bone mineral density (BMD) on Dual-energy X-ray absorptiometry (DXA) scanning most commonly reflects metabolic bone disease. However, some malignancies could also stimulate the underlying processes. We reported that a 41-year-old female was referred for lumbago. She did not complain of any symptoms in the digestive system. DXA revealed high BMD in the lumbar vertebras. Marked increase in bone mass was observed in an X-ray of chest compared with one conducted 6 months previously. Additionally, an X-ray of the axial skeleton showed diffuse sclerotic change...

Bisphosphonates have emerged as an important tool in the supportive care of women with early breast cancer. Whereas traditionally, these drugs have been part of the treatment of osseous metastasis, the key role of bisphosphonates in preserving bone health in patients with early breast cancer cannot be overemphasised. Currently the most established use of bisphosphonates in early breast cancer patients is in women receiving hormonal blockade, mostly aromatase inhibitors (AI), with concomitant osteopenia. To that end, it is recommended that every woman undergo a Dual Energy X-Ray absorptiometry (DEXA) scan before commencement of an AI and annually during the treatment duration...

OBJECTIVES: To examine Japanese patients who had received androgen-deprivation therapy (ADT) for longer periods, as it is known that ADT of patients with prostate cancer reduces their bone mineral density (BMD). However, our previous cross-sectional study revealed that short-term ADT (average, 23.5 months) does not significantly increase the prevalence of osteoporosis in Japanese patients. METHODS: The subjects consisted of 201 native Japanese patients with prostate cancer...

SAPHO syndrome is an acronym for a clinical entity characterized by synovitis, acne, palmoplantar pustulosis, hyperostosis, and osteitis. The association of sterile inflammatory bone lesions and neutrophilic skin eruptions is indicative of this syndrome, even though not all components always coexist. We report a case of a 62-year-old female presenting with a lytic manubrial lesion. Diagnoses of metastasis or infection were initially entertained but excluded on open biopsy, and SAPHO syndrome was confirmed on additional investigation and follow-up...

Experiments were conducted to determine optimal acquisition techniques for bone image decompositions for a prototype dual-energy (DE) imaging system. Technique parameters included kVp pair (denoted [kVp(L)/kVp(H)]) and dose allocation (the proportion of dose in low- and high-energy projections), each optimized to provide maximum signal difference-to-noise ratio in DE images. Experiments involved a chest phantom representing an average patient size and containing simulated ribs and lung nodules. Low- and high-energy kVp were varied from 60-90 and 120-150 kVp, respectively...

Response to systemic therapy in breast cancer patients with lytic skeletal metastases manifests as a shift from increased bone resorption to new bone formation. We hypothesized that dual-energy x-ray absorptiometry (DXA) could be used to prospectively quantitate changes in bone mineral density (BMD) in metastatic skeletal lesions in breast cancer patients receiving systemic therapy. Nine metastatic breast cancer patients with one or more assessable lytic skeletal metastases receiving systemic therapy were prospectively evaluated with DXA, skeletal radiographs, computed tomography (CT), and radionuclide bone scans at baseline (t = 0 months, 2 months, and 6 months)...
