Introduction: The gastrin releasing peptide (GRP) receptor is over expressed in a variety of common human tumors. Radiolabeled bombesin analogues have exhibited high binding affinity for these receptors. The aim of this study was to assess the value of a new 99mTc-bombesin analog in the differentiation of malignant from benign breast tumors. Methods: 99mTc-bombesin scans ...
OBJECTIVES It is difficult to investigate the whole-body distribution of an orally administered drug by means of positron emission tomography (PET), owing to the short physical half-life of radionuclides, especially when 11C-labeled compounds are tested. Therefore, we aimed to examine the whole-body distribution of donepezil (DNP) as an acetylcholinesterase inhibitor by means of 11C-DNP PET ima...
The accumulation of calcium-phosphate complexes in soft tissues is frequent in patients with autoimmune diseases such as dermatomyositis or polymyositis. It is hard to establish a diagnosis unless there is prominent muscle or skin involvement and biopsy is the procedure of choice to reveal the calcification. Whole-body bone scanning can be used in assessing the soft tissue calcification and the...
We report a case of a multicentric form of Castleman's disease with multiple lymph nodes showing intense FDG uptake on whole body scan mimicking non-Hodgkin's lymphoma. In this report, the patient had multiple cervical, mediastinal, hilar, retroperitoneal and abnormal lymph nodes in the groin. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography was performed before tissue ...
Therapy with radioiodine (I-131) has been used for patients with well-differentiated thyroid cancer such as papillary and follicular thyroid carcinoma to ablate normal thyroid tissue or to treat metastatic lesions. The improvement of survival rates and decrease of recurrence rates after I-131 therapy has been documented by retrospective studies (Mazzaferri & Jhiang, 1994; Samaan et al., 1992). ...
UNLABELLED CT has become an established method for calculating body composition, but it requires data from the whole body, which are not typically obtained in routine PET/CT examinations. A computerized scheme that evaluates whole-body lean body mass (LBM) based on CT data from limited-whole-body coverage was developed. The LBM so obtained was compared with results from conventional predictive ...
The appearance of a hot kidney on bone scintigraphy is rare and can be seen due to various factors. In our clinic, we observed hot kidney appearance in two patients to whom technetium-99m methylene diphosphonate (Tc-99m MDP) whole body scan has been performed: a young male adult at the age of 18 who was diagnosed with acute lymphocytic leukemia with a presumptive diagnosis of avascular necrosis...
