The appearance of a hot kidney on bone scintigraphy is rare and can be seen due to various factors. In our clinic, we observed hot kidney appearance in two patients to whom technetium-99m methylene diphosphonate (Tc-99m MDP) whole body scan has been performed: a young male adult at the age of 18 who was diagnosed with acute lymphocytic leukemia with a presumptive diagnosis of avascular necrosis...

PURPOSE Pain related to costovertebral and costotransverse joints is likely an underrecognized and potentially important cause of thoracic back pain. On combined single-photon emission computed tomography and computed tomography (SPECT-CT), increased technetium-99m methylene diphosphonate (99mTc MDP) activity at these articulations is not uncommon. We evaluated whether this activity corresponds...

Radiopharmaceuticals are known to interact with the blood components (i.e. the red blood cells, serum proteins etc) but so far, there have been no data regarding their purely mechanical trapping in thrombi. The experiments presented in this communication provide evidence that the technetium-99m labeled albumin macroaggregate ((99m)Tc-MAA), apparently due to its particle size, can be almost quan...

A case of a woman aged 46 years with signs of rhabdomyolysis and acute renal failure is presented. Coxsackie serum test was positive. Increased uptake of Technetium-99m methylene diphosphonate (99mTc-MDP) by muscles of thighs and calves was observed. After 1 year no increased accumulation of radiotracer in the muscles was found.

A 72-year-old woman had insidious onset of heart failure, and was diagnosed as multicentric Castleman's disease. She underwent myocardial imaging with technetium-99m tetrofosmin, 1-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP). Technetium-99m tetrofosmin studies showed almost normal uptake of the left ventricular myocardium indicating normal myocardial perfusion. 1-123 BMIPP showed redu...

Bone scans are widely utilized for detection of metastases from bone sarcomas. Technetium methylene diphosphonate scan ([(99m)Tc]MDP) is one of the most popular radiotracers used for that purpose. Lymphatic spread of bone sarcomas is unusual and often difficult to diagnose. Unfortunately, bone scans are not as sensitive in demonstrating lymphatic spread of sarcomas as they are at demonstrating ...

AIM To evaluate the role of 99m-technetium methylene diphosphonate (Tc-99m MDP) bone scintigraphy on the detection of joint damage in asymptomatic alpine ski racers. MATERIALS AND METHODS This study included 20 male asymptomatic alpine ski racers (age range: 18-21 years). None of the skiers had a history of ski crashes. Bone scan findings of the racers were examined with Tc-99m MDP bone scint...

Current nuclear imaging of the skeletal system is achieved using technetium-99m (Tc-99m) methylene diphosphonate (MDP), F-18 sodium fluoride (NaF), or F-18 fluorodeoxyglucose (FDG). However, comparisons of these are rare in the literature. We present a case of a 51-year-old female with suspicious lung cancer due to main symptoms of dyspnea, nonproductive cough, and pleural pain. Tc-99m MDP whol...

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...
