a 57-year-old male with history of prostatectomy, cyctectomy, cecal urinary diversion for invasive prostate cancer and with a recent rise in psa level, was referred for bone scintigraphy to rule out osseous metastatic disease. an interesting finding was abnormal tracer accumulation throughout the large bowel, which was proved to be due to urinary diversion.

Static bone scan was performed in 46 patients for evaluation of ocular Hydroxyapatite Vascularization. Study Findings indicated that bone scan, with TC-99m MDP is an appropriate method for evaluation of Hydroxyapatite Vascularization and for estimating the time For peg insertion into the Hydroxyapatite implant. Our study showed proper Hydroxyapatite Vascularization when the ratio of activ...

a 10-year-old boy was referred to us for evaluation of fuo accompanied with bone pain in both calves. three hours after intravenous injection of 13 mci of 99mtc-mdp, whole body scan in multiple spot views was performed. the scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. histopathologic evaluation confirmed osteosclrosis and fibrotic changes without an...

A 10-year-old boy was referred to us for evaluation of FUO accompanied with bone pain in both calves. Three hours after intravenous injection of 13 mCi of 99mTc-MDP, whole body scan in multiple spot views was performed. The scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. Histopathologic evaluation confirmed osteosclrosis and fibrotic changes...

skeletal metastasis is one of the most important disabling complications of the malignant diseases. as in general, the survival of patients with osteometastatic lesions is relatively long, an early diagnosis can lead to improve the patient’s life, both quantitatively and qualitatively, and prevent exacerbation of the disease and disabling complications. in this study, 22 patients with establish...

Incidental extra-osseous uptake of 99mTc-MDP on bone scintigraphy has been frequently reported in the literature; however, calcification of the psoas muscle is a rare condition, which has been reported on magnetic resonance (MR) and computed tomography (CT) imagings. Here we report a 67-year-old woman with acute paraplegia and low back pain who was referred for a 99mTc-MDP...

With rising incidence of breast carcinoma in Asian population, staging workup remains a crucial entity diseasemanagement and outcome. Bone scintigraphy for detection osteoblastic metastasis has remained convenient choice.However, the presence underlying lytic bony lesions sensitivity 99mTc-MDP bone scan is questionable when comparedto 18F-FDG PET-CT scan. We present case that showed better pick...

PURPOSE 99mTc-3PRGD2, a promising tracer targeting integrin receptor, may serve as a novel tumor-specific agent for single photon emission computed tomography (SPECT). A multi-center study was prospectively designed to evaluate the diagnostic accuracy of 99mTc-3PRGD2 imaging for bone metastasis in patients with lung cancer in comparison with the conventional 99mTc-MDP bone scan. METHODS The p...

Radionuclide 99mTc-MDP planar bone scan is the most commonly performed nuclear medicine procedure and may aid diagnosis of benign and malignant bone pathologies. 99mTc-MDP is injected intravenously and subsequently taken up by osteoblasts and incorporated into the bone matrix. In the process it acts as a marker for new bone formation, bone turnover and local vascularity. The high sensitivity of...
