PURPOSE We compared signal change on magnetic resonance imaging (MRI) with fat suppression and bone scan activity of lumbar facet joints to determine if these two imaging findings are correlated. METHODS We retrospectively identified all patients who underwent imaging of the lumbar spine for pain evaluation using both technetium-99m methylene disphosphonate single-photon emission computed tom...

a nine-month old male child presented with low-grade fever, loose stools and facial puffiness. clinically patient was otherwise normal except for a firm liver on palpation. the laboratory tests revealed hypoproteinemia (both albumin and globulin) and iron deficiency anemia. differential diagnosis considered were: 1. nephrotic syndrome, 2. cystic fibrosis (in view of recurrent diarrhea and respi...

A report is presented of a liquefaction necrosis of mitral annular calcification in a patient with chronic renal failure and secondary hyperparathyroidism who had been managed by hemodialysis for 11 years. The mass was echogenic with an echo-lucent area inside, high density on computed tomography and low intensity on magnetic resonance imaging. The uptake of gallium-67 (67Ga)-citrate and the bo...

The value of 99mTc-Methylene diphosphanate (99mTc-MDP) bone scan in predicting development of bony destruction, swelling, new bone erosions and skeletal deformities in small joints and bones was studied by visual evaluation of bone scans. 99m Tc-MDP was injected intravenously. 3 hours after the 99mTc-MDP injection, they have been underwent spot views of entire skeletons with planar scintigraphy...

UNLABELLED The aim of this study was to assess the value of 99mTc-hexakis2-methoxyisobutylisonitrile (MIBI) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. METHODS The scintigraphic findings for 84 patients were compared with the surgical and histologic findings. Each patient underwent three-phase bone scanning with 99mTc-methyle...

OBJECTIVE The aim of this study was to compare the metabolic activity of metastatic foci from breast and prostate cancer patients as scanned by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and by technetium-99m methyl diphosphonate (99mTc-MDP) bone scan (BS). SUBJECTS AND METHODS Forty one patients were studied, divided into 2 groups based o...

Osteopoikilosis is a benign but rare condition characterized by bone islands throughout the osseous tissue, which could be easily confused with bone metastasis. We present a case of a 37-year-old man presented to orthopedic outpatient clinic with right hip pain for 2 weeks. There were multiple, small punctate lesions scattered throughout the skeleton on radiograph. Subsequent Tc-99m methylene d...

BACKGROUND Metastatic pulmonary calcification (MPC) is rarely reported in primary hyperparathyroidism, especially MPC develops quickly. We report such a case here with a literature review. CASE PRESENTATION A 41-year-old woman presented with cough and dyspnea. Data from clinical, radiological, pathological, technetium (99mTc)-methylene diphosphonate (MDP) bone scintillation imaging, and 99mTc...

BACKGROUND Scintigraphic studies have been performed to assess the release, both in vitro and in vivo, of radiotracers from tablet formulations. Four different tracers with differing physicochemical characteristics have been evaluated to assess their suitability as models for drug delivery. METHODS In-vitro disintegration and dissolution studies have been performed at pH 1, 4 and 7. In-vivo s...
