Langerhans cell histiocytosis (LCH) is a benign disorder related to the histiocytes which can infiltrate bone tissue. The most effective method for demonstrating severity of this disease is PET/CT and bone scintigraphy might show bone lesions. We present a seventeen year old male patient with disseminated LCH presented with exophtalmos and having multiple vertebral lesions which were identified...

PURPOSE The aim of this study is to specify the precise role of bone scintigraphy and serum CEA and CA 15-3 assays in the monitoring of breast cancers in order to optimize their use and to determine whether it is possible to guide the prescription of bone scan by the use of CEA and CA 15-3 assays in the monitoring of breast cancer. METHODS For this purpose, from November 1997 to May 2002, 98 ...

the aim of this study was to assess the value of 99mtc-hexakis-2-methoxyisobutylisonitrile (mibi) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. methods: the scintigraphic findings for 84 patients were compared with the surgical and histologic findings. each patient underwent three-phase bone scan with 99mtc-methylene diphosphonat...

We compared MRI, CT and bone scintigraphy in the examination of experimentally produced metastatic bone tumors. Three Japanese white rabbits with VX-2 bone tumor were used. T1 weighted (T1W) and T2 weighted (T2W) images were obtained in each MRI examination. All the tumors distributed from the bone marrow to the extraosseous region. T2W images were the best to detect the extraosseous tumors. CT...

Background. Numerous possible artifacts may render the evaluation of bone scans difficult. Case reports. This article provides a pictorial survey of both typical and extraordinary pitfalls in bone scintigraphy, which are caused by increased or reduced tracer accumulation of soft tissue or bone. Conclusions. One should be aware, that in individual patients, "artifacts" in bone scintigraphy lead ...

Creatine kinase-MB isoenzyme release (CK-MB-g-Eq) was correlated with left ventricular (LV) radionuclide gated blood pool wall motion estimates of percent abnormally contracting regions (%ACR), ejection fraction (EF) and quantitative thallium-201 (Tl-201) LV perfusion scintigraphy (Tl-201 perfusion index) during evolving myocardial infarction (MI). Of the 35 patients, 14 had no evidence of eith...

There are two main Nuclear Medicine techniques, the gastroesophageal reflux scintigraphy with late lung imaging and the nuclear salivagram, for diagnosis of pulmonary aspiration. Each of the techniques can document the two different, antegrade and retrograde, routes of pulmonary aspiration. In this report, we presented a patient with recurrent respiratory problems and emphasized the importance ...
