Bone scintigraphy is an extremely valuable technique in diagnosis and treatment planning for patients with condylar hyperplasia (CH). The main objective of this study was to develop approach determine normal activity values the mandibular condyles, adjusted age sex, through quantitative analysis bone single-photon emission computed tomography (SPECT) on a condyle-by-condyle basis compare these ...

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...

One month later the patient received 4.22 GBq (114 mCi) 153Samarium-EDTMP for palliation of severe bone pain. Post treatment, whole body 153Samarium scan was also a “superscan” showing very similar osseous metastases pattern to the 99mTc-MDP bone scan. Anterior and posterior whole body images 24 hours after intravenous administration of 153Sm-EDTMP demonstrate diffuse osseous metastases in a ve...

UNLABELLED The aim of this study was to investigate joint scintigraphy in rabbits with 99mTc-N-[3-(triethylammonio)propyl]-15ane-N5 (NTP 15-5), a new radiopharmaceutical that specifically localizes in cartilaginous tissues. METHODS Scans obtained after intravenous injection of the 99mTc-labeled compound in normal and arthropathy-induced rabbits were compared with those of the bone-imaging age...

Os acromiale is an anatomic variant that in rare cases can cause pain. (99m)Tc-methylene diphosphonate bone scintigraphy with SPECT/CT can play an important role in diagnosing this clinical entity. We present a male football player with shoulder pain secondary to a symptomatic os acromiale, and we demonstrate the findings on bone scanning with limited SPECT/CT that diagnosed this important clin...

PURPOSE To investigate the clinical value of (99)Tc(m)-MDP SPECT for the diagnosis of unilateral condylar hyperplasia (UCH). METHODS One hundred forty-nine patients who underwent mandibular (99)Tc(m)-MDP SPECT between January 2009 and December 2012 were studied, including 105 cases that were clinically suspected of UCH and 44 comparable cases without UCH as a control group. RESULTS Increase...

In order to investigate the feasibility of the assessment of renal function with 99mTc-MDP, we compared renographical images, renogram patterns and the glomerular filtration rate (GFR) obtained by means of a modified Gates' method and 200 MBq of 99mTc-MDP with those obtained by means of 99mTc-DTPA. Because 19 of 20 patients had malignant tumors in the genitourinary tract, there was no differenc...

Although extraosseous accumulations of 99mTc phosphate complexes are phenomena which can often be seen, no case showing extraosseous accumulation to brain tumor on SPECT has been reported. We report here two cases of primary brain tumor showing extraosseous accumulation of 99mTc phosphate in bone SPECT. 201Tl SPECT also showed increased 201Tl uptake by the tumor. Comparing bone SPECT with 201Tl...

A 40-year-old man presented with decreased mental ability and acute renal failure. He had played computer games for 3 days without rest and proper oral intake before coming to our hospital. On admission, serum creatinine was 10.1mg/dl. Urinalysis showed dysmorphic red blood cell (16–20/HPF) and proteinuria. Serum creatinine kinase was 13 840U/l (normal range, 5–217) and serum myoglobin was 8621...
