FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...

Background: Melorheostosis has been discussed infrequently in the nuclear medicine literature. A 25-year-old female patient presented with a one-year history of b:union: pain, sclerotic change and skin pigmentation on the left big toe interphalangeal joint. Ulceration, poor healing and hyperkeratoses of the wound were noted post debridement. The plain film of the left foot incidentally showed m...

osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...

clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...

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...

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 de...

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...

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...

Multifocal skeletal tuberculosis in not uncommon in the countries with tuberculosis. The clinical onest is insidious and sometimes nonspecific, resulting in delay or misdiagnosis. Bone scan appearance is presented in some reports, as multiple abnormal accumulations of tracer. This report describes an unusual presentation of multifocal skeletal tuberculosis.

necrotizing fasciitis is a part of a spectrum of necrotizing soft tissue infections that usually follow a surgical intervention or a chronic / acute medical illness. diagnosis is often based on symptoms which classically start within hours after an injury. there are no reports on the use of pet/ct in this condition. sparing reports of its association in patients with malignancy (ca of colon and...
