A 52 year old man developed a painful swollen left knee. Clinically there was an effusion and radiographs showed local osteoporosis. Sepsis was suspected but tests proved negative and the symptoms gradually settled. During the course of the following year he developed similar pain migrating from the left foot to the right knee then to the right foot. Investigations showed a right knee effusion ...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

Background: Screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (APN). Diuretic Tc-99m mercaptoacetyltriglycine (MAG3) scintigraphy with zero time injection of furosemide (MAG3-F0) was observed to display focal parenchymal disorders. The advantages of MAG3 include: lower radiation dose and short duration of the test. The aim of this study was to...

Bone scintigraphy is widely considered as an important technique able to investigate various pathological conditions of the skeletal system. Many unexpected extraosseous uptakes have been reported in literature. We present here three cases of unexpected 99mTc-oxidronate (HDP) myocardial extraosseous uptakes in patients undergoing bone scan for staging purposes. In particular, we present the fir...

An approach to assist the determination of the best time-after-injection for taking an scintigram in bone scanning is proposed. More precisely, a technique is discussed to estimate the evolution of the portions, in different compartments of the body, of the injected dose using a model of the radionuclide distribution dynamics, the available measurements and information on variations of the para...

Two pediatric cases are described in which the results of each patient's bone scan demonstrated abnormal stomach uptake. There have been a number of reports in the literature describing stomach uptake of bone agents, however, it is an uncommon finding.

This prospective study assessed risk factors for discharge from basic training (BT) among 2,137 male Marine Corps recruits between February and April 2003. Physical and demographic characteristics, exercise, and previous lower extremity injuries before arrival at Marine Corps Recruit Depot were assessed by questionnaire during intake processing. Stress fractures were confirmed by x-ray, triple-...

This paper overviews the problem of the clinical basis, diagnosis and available therapy modalities for lymphoedema. Regarding diagnostics, the measurement of circumference, volume and thickness of the limb are presented, as well as diagnostic imaging modalities. These include direct and indirect lymphography, MRI, CT, ultrasound imaging and lymphoscintigraphy, which is currently considered the ...

Numerous injuries and pathologic conditions can involve the hallucal sesamoidal complex and plantar capsular structures of the first metatarsophalangeal joint. Although clinical history and presentation are important in developing a reasonable differential diagnosis, there is often considerable overlap in the clinical presentation and physical findings between various pathologic entities. Imagi...

Tarsal navicular stress fractures present a difficult diagnostic and treatment dilemma for the orthopedic physician of an active individual. Patients often complain of diffuse, poorly-defined symptoms and have a paucity of physical findings. Initial diagnostic evaluation often. fails to recognize navicular stress fractures which results in delayed diagnosis and treatment. A bone scan is sensiti...
