UNLABELLED (18)F-FDG PET/CT is used for detecting cancer and monitoring cancer response to therapy. However, because of the variable rates of glucose metabolism, not all cancers are identified reliably. Sodium (18)F was previously used for bone imaging and can be used as a PET/CT skeletal tracer. The combined administration of (18)F and (18)F-FDG in a single PET/CT study for cancer detection ha...

Background: Bone sarcomas are the most common malignancies of bone tissues in children, and are classified intotwo groups as osteosarcoma and Ewing’s Sarcoma. Treatment and prognosis depend on the subtype and grade ofthe tumor. The goal of this study was to evaluate the features bone sarcoma in patients referred to MAHAK childrenhospital since 2007 to 2009.Materials and Methods: This was a retr...

OBJECTIVE To determine the incidence of intracranial injury, specifically in the temporal lobe, in patients with longitudinal fractures of the temporal bone. DESIGN Prospective inception cohort. SETTING University of Maryland Division of Otolaryngology-Head and Neck Surgery and the Maryland Shock Trauma Center, Baltimore. PATIENTS Twenty-seven consecutive patients with unilateral or bilat...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

OBJECTIVES The aim of this study was to assess the cost effectiveness of multiple competing diagnostic strategies for suspected scaphoid fractures. METHODS With published data, the authors created a decision-tree model simulating the diagnosis of suspected scaphoid fractures. Clinical outcomes, costs, and cost effectiveness of immediate computed tomography (CT), day 3 magnetic resonance imagi...

PURPOSE Rates of evaluation and treatment for osteoporosis following distal radius fragility fractures remain low. As a subset of patients with these fractures undergo diagnostic computed tomography (CT) scan of the wrist, utilizing bone mineral density (BMD) measurements available with this imaging can be used to detect osteopenia or osteoporosis. This information may consequently prompt inter...

PURPOSE To assess the characteristics of bone metastasis from hepatocellular carcinoma and the radiation field arrangement based on imaging studies. MATERIALS AND METHODS Fifty-three patients (84 lesions) with bone metastasis from a primary hepatocellular carcinoma completed palliative radiation therapy. All patients underwent one of following imaging studies prior to the initiation of radiat...

Background: Cholesteatoma is potentially dangerous condition as it can extend and erode into adjacent structures and can cause various serious complications. HRCT temporal bone very clearly depicts the anatomy of various small important structures in middle and inner ear cavity. Hence it is an excellent modality and investigation of choice in diagnosing and defining the extent of cholesteatoma....
