AIM To prospectively investigate the role of MR spectroscopy (MRS) and diffusion-weighted magnetic resonance imaging (DWI) in assessing vertebral marrow changes in postmenopausal women. MATERIALS AND METHODS Fifty postmenopausal women, who underwent dual-energy x-ray absorptiometry of the spine, were divided into three bone density groups (normal, osteopenia, and osteoporosis) based on T-scor...

Abstract Primary bone sarcomas account for less than 1% of diagnosed cancers each year. In this era multiplanar and functional imaging, the approach to radiographic diagnosis goes much beyond traditional radiography. Radiographs are still most pertinent part initial tumors. Multimodal such as computed tomography (CT) magnetic resonance imaging (MRI), can help with issues complex anatomy, marrow...

Background: There are multiple methods for acceleration of bone healing. Bone marrow has been shown to contain osteoprogenitor cells. Objective: To determine the effect of percutaneous bone marrow injection on bone healing. Methods: 15 mature, 2-kg-weighing white New Zealand rabbits from both sexes were randomized into 3 groups: Group I: Only osteotomy of right radius was performed and a 5 mm b...

PURPOSE Bone marrow biopsy is a standard method for the evaluation of bone marrow infiltration by lymphoma; however, it is an invasive and painful procedure. Fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) is a noninvasive imaging technique with the potential to detect bone marrow involvement by lymphoma. MATERIALS AND METHODS We retrospectively reviewed medic...

We present a 63-year-old male patient with intractable bone pain and rapidly progressive osteoporosis, who was diagnosed multiple myeloma (MM) by CT despite normal magnetic resonance imaging (MRI) findings. The gold standard diagnostic modality for MM is MRI as it can be used to sensitively evaluate marrow, however, the current case highlights that not always accurate in evaluating MM. combinat...

objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...

Fifteen months after right lobe lobectomy with adjunctive radiation therapy for squamous cell carcinoma, a patient 53-yr-old man underwent Tc-99m depreotide chest single photon emission tomography (SPECT). In addition to two focal areas of abnormally increased uptake in the right lung, the Tc-99m depreotide SPECT showed cold areas in the middle thoracic vertebrae. Photopenic areas in the 6th an...

background: bone marrow transplant (bmt) recipients are prone to bacterial, viral and fungal infections. bacterial infec­tion is considered as one of the common and serious complications in bone marrow transplant recipients. the aim of this study was to determine the rate of bacterial infections in bone marrow transplant recipients. methods: fifty-two blood and 25 catheter samples were obtained...

Imatinib mesylate is an effective, small-molecule, selective tyrosine kinase inhibitor, which inhibits BCR-ABL in patients with chronic myeloid leukemia, c-kit gastrointestinal tumor (GIST), and platelet-derived growth factors hypereosinophilic syndrome. Above all, bone marrow necrosis a rare complication of imatinib usage. If newly developed increased opacity lesions are seen metastatic GIST, ...
