OBJECTIVE To report a rare case of extramedullary hematopoiesis (EMH) with an asymptomatic intrapelvic mass in a patient with thalassemia major. CLINICAL PRESENTATION The patient presented with a pelvic mass discovered by ultrasonography before undertaking laparoscopic cholecystectomy for gallstones. Technetium-99m MDP bone scan failed to differentiate EMH from malignancy. A fine-needle aspir...

Focal tracer uptake in the jaw during conventional bone scintigraphy is a quite frequent finding usually due to dental disease and seldom to other diseases including malignant disease. Methylene diphosphonate-technetium-99m ((99m)Tc-MDP) 3-phase bone scan is considered the most sensitive imaging method for the detection of jaw osteonecrosis at an early stage. This finding can also but seldom be...

Super scan is a well-known finding described in skeletal scintigraphy characterized by uniform symmetrically increased radiopharmaceutical uptake by bones and consequently diminished renal parenchymal activity. Sy et al. hypothesized that the faint visualization of renal cortex in bone scintigraphy might be the result of increased uptake of radiopharmaceutical by pathologic bones and reduced ph...

multifocal avascular osteonecrosis is an uncommon entity having a predominant association with steroids and less commonly with alcohol abuse. in literature only few cases of alcohol induced multifocal avascular osteonecrosis involving both hips and shoulder are reported. to the best of our understanding this is the first case report or contribution from nuclear medicine court and it would help ...

despite the long history of the worldwide use of bacillus calmette-guerin (bcg) vaccine, a wide spectrum of adverse reactions has been observed in a small proportion of immunized infants; the most severe complication, disseminated bcgitis, is often fatal but exceedingly rare and is considered to result from host immunodeficiency. at present, ct scan, ultrasound, x-ray and bone marrow aspiration...

BACKGROUND Skeletal uptake of 99mTc labelled methylene diphosphonate (99mTc-MDP) is used for producing images of pathological bone uptake due to its incorporation to the sites of active bone turnover. This study was done to validate bone turnover markers using total skeletal uptake (TSU) of 99mTc-MDP. METHODS 22 postmenopausal women (52-80 years) volunteered to participate. Scintigraphy was p...

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...
