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...

Diffuse pulmonary deposition of [99mTc]methylene diphosphonate (MDP) as well as abnormalities characteristic of hypertrophic pulmonary osteoarthropathy have been observed in a patient with Pneumocystis carinii pneumonia (PCP). The findings of the bone scan together with those in the corresponding scintigraphy, and roentgenograms of the chest and skeletal structures are presented. Parallel rever...

body skeletal scintigraphy performed with 20 mCi (740 Mega Becquerel) of Technetium-99m Methylene DiphosPhonate (MDP) revealed diffusely increased tracer uptake over body of sternum and manubriosternal junction suggestive of neoplastic process. A focal area of benign uptake was also seen over left 2nd costochondral junction (Fig. 3). Contrast enhanced CT study revealed mixed sclerotic and lytic...

Introduction Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disorder of unknown ethiology. The clinical manifestations of CRMO are highly variable. One to 20 sites can be affected at one time. Since CNO is a systemic disorder that can affect multiple skeletal sites, whole-body imaging techniques (Tc-99 bone scintigraphy or MRI) provide major contribution to the in...

Osteopoikilosis (OPK) is a rare disease with an unknown etiology. Although a benign condition, it may lead to diagnostic problems when the patient undergoes diagnostic imaging of the skeletal system due to various reasons like malignancy. Herein, we report 2 cases with OPK causing difficulties in the final diagnosis of the cases which was resolved with the contribution of bone scintigraphy and ...

The present studies performed in experimental animals demonstrate that electrical direct current cardioversion can produce skeletal muscle damage and increased technetium-99m stannous pyrophosphate (99mTc-PYP) uptake; in experimental animals the electrically damaged skeletal muscle shows necrosis with extensive calcium deposition. In addition, the frequent administration of high energy cardiove...

Low back pain of various etiologies is a common clinical presentation in young athletes. In this article, we discuss the utility of SPECT/CT bone scintigraphy for the evaluation of low back pain in young athletes. The spectrum of lower spine lesions caused by sports injuries and identifiable on bone scan is presented along with strategies to avoid unnecessary irradiation of young patients. Also...
