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 decrease...

chronic recurrent multifocal osteomyelitis (crmo) is an inflammatory bone disease usually affecting children. a 9-year old boy presented with recurrent lower extremities pain and discomfort lasting for two years. in every time, symptoms vanished after several weeks. the patient received antibiotics only in one period of bone pain. in other occasions the patient didn’t received any antibiotics. ...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

Background: Bone lesion in multiple myeloma (MM) is most commonly presented as a lytic lesion in this disease. Determination of extent of bone lesions in MM is necessary to follow-up the patients. Whole body bone scan with 99m, Tc-methylene diphosphonate (MDP) has a lower sensitivity than other modalities. Methods: From the patients with MM admitted to Ayatollah Rouhani Hospital of Babol-Iran ...

multifocal avascular osteonecrosis is an uncommon entity having a predominant association with steroids and less commonly with alcohol abuse. in literature only few cases of alcohol induced multifocal avascular osteonecrosis involving both hips and shoulder are reported. to the best of our understanding this is the first case report or contribution from nuclear medicine court and it would help ...

despite the long history of the worldwide use of bacillus calmette-guerin (bcg) vaccine, a wide spectrum of adverse reactions has been observed in a small proportion of immunized infants; the most severe complication, disseminated bcgitis, is often fatal but exceedingly rare and is considered to result from host immunodeficiency. at present, ct scan, ultrasound, x-ray and bone marrow aspiration...

in spite of very high sensitivity, bone scan is quite nonspecific in evaluation of bony lesions. in interpretation of bone scan special attention to patient’s clinical presentation and correlation with other lab and imaging modalities should be paid. in this report a patient with erdheim chester disease a rare and unusual form of lipidosis is presented and the pattern of 99mtc-mdp bone scan and...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...

abstract background: osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. in the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. in this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ilp) for treatment of osteoid osteoma in iranian patients. materials and methods: in this case s...
