UNLABELLED Quantitative studies of bone using (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) have a potentially valuable role in investigating the treatment of patients with metabolic bone disease. In this study we compared 3 different methods of measuring whole-skeleton (99m)Tc-MDP plasma clearance (K(bone)) in 12 osteoporotic postmenopausal women (mean age, 67.3 y) before participation in a cl...

We describe a patient with newly diagnosed limy cancer. Staging was performed with CT and mediastinoscopy. FDG PET scan was performed and confirmed increased metabolic activity in the primary tumor as well as the hilar lymph node. Seven months after initial presentation, the patient was found to have two lytic lesions in the pelvis on plain radiograph. Hone scan was negative but PET demon...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...

background: osteoporosis is a systemic skeletal disorder characterized by low bone mineral density (bmd) that leads to an increase in bone fragility, causing an individual to be at an increased risk for fractures. asian-indians are at an increased risk for developing osteoporosis. considering the number of asian-indians in the us is rapidly growing, they likely could be an underappreciated popu...

CT) is a noninvasive radionuclide-based whole body imaging technique which combines both a Positron Emission Tomography (PET) scanner and an x-ray Computed Tomography (CT) scanner in a single gantry system. In PET, functional images are obtained which denotes spatial distribution of metabolic or biochemical activity in the body. These images are aligned with anatomical images obtained by CT sca...

OBJECTIVES It is difficult to investigate the whole-body distribution of an orally administered drug by means of positron emission tomography (PET), owing to the short physical half-life of radionuclides, especially when 11C-labeled compounds are tested. Therefore, we aimed to examine the whole-body distribution of donepezil (DNP) as an acetylcholinesterase inhibitor by means of 11C-DNP PET ima...

Hepatitis C-associated osteosclerosis (HCAO) is an uncommon condition characterized by increased bone density, skeletal pain and elevated bone formation markers. Since 1992, only 17 cases have been reported. We herein describe the case of a 61-year-old woman affected by severe pain involving the lower limbs. The laboratory data showed an elevated serum alkaline phosphatase level, and the patien...

RATIONALE Camurati-Engelmann disease (i.e., progressive diaphyseal dysplasia) is an extremely rare autosomal dominant bone disorder. The most common clinical manifestations were chronic skeletal pain, waddling gait, muscular weakness. PATIENT CONCERNS We described that a 27-year-old male with a 1-year history of intermittent tetany was referred for bone scintigraphy. The whole body bone scan ...
