We prospectively studied 86 children to assess the value and accuracy of isotope bone scanning in the diagnosis of suspected acute haematogenous osteomyelitis and septic arthritis. The patients were scanned because of difficulty in localising the exact site of the pathology. Characteristic scan appearances were found. In osteomyelitis there was increased or decreased uptake extending beyond the...

diagnosis: stated earlier, bone scan is quite non specific and exceptions prove the rule. Regional pain that aggravates at Radionuclide imaging is perhaps the only means to image night in a young patient is quite typical of osteoid osteoma. the physiology of skeletal system. About 30% of mineral Osteoid osteoma and fibrous dysplasia are two entities loss must take place before an abnormality be...

OBJECTIVE The aim of this study is to evaluate the efficiency of gamma probe guided osteoid osteoma surgery and the applicability of quantitative analyses obtained from preoperative bone scan images. MATERIAL AND METHODS This study involved 12 osteoid osteoma patients who were treated with gamma probe guided surgery after preoperative bone scan. The calculated contrast ratios between nidus an...

Unilateral condylar hyperplasia is the main cause of mandibular asymmetry. Radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. In this study, 39 patients with normal bone scan and no facial asymmetry were studied. All patients were below 22 years of age. Normal condylar uptake was determined in this group of patients. Right & left condyla...

BACKGROUND To determine when a bone scintigraphy investigation is appropriate in patients with newly diagnosed prostate cancer (PCa). METHODS We retrospectively reviewed 703 newly diagnosed PCa patients who were referred for bone scintigraphy. The association between age, prostate specific antigen (PSA), Gleason score (GS) and bone scintigraphy result were investigated by series of crude or s...

We present the complete construction methodology for an anatomically accurate mouse phantom made using materials which mimic the characteristics of tissue, lung, and bone for radiation dosimetry studies. Phantoms were constructed using 2 mm thick slices of tissue equivalent material which was precision machined to clear regions for insertion of lung and bone equivalent material where appropriat...

background: otalgia and bell’s palsy are rare manifestations of metastasis and the most common presentation of an inflammatory process in the temporal bone. case presentation: this article explains a 34-year-old woman with breast cancer who presented with cranial nerve palsy symptoms. the 7th and 8th cranial nerves were involved in the metastatic phase and then hoarseness was added to her sympt...

The past few years have witnessed an impressive growth in the number of bone-scanning procedures, primarily for nonmalignant disease, and this in turn has stimulated investigative efforts to understand better the principles and mechanisms of skeletal tracer localization. The time appears ripe, there fore, to summarize briefly this newer knowledge. A detailed evaluation of older, basic informati...
