Background: 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/ CT) has become an established method for detecting hypermetabolic sites of known and occult disease and is widely used in oncology surgical planning. Intraoperatively, it is often difficult to localize tumors and verify complete resection of tumors that have been previously detected on diagnostic...

BACKGROUND Fluorodeoxyglucose (18FDG) PET/CT imaging has become an important component of the management paradigm in oncology. However, the significant imparted radiation exposure is a matter of growing concern especially in younger populations who have better odds of survival. The aim of this study was to estimate the effective dose received by patients having whole body 18FFDG PET/CT scanning...

Hellenic Journal of Nuclear Medicine • September December 2009 291 To the Editor: The Hell J Nucl Med has printed an article comparing technetium-99m pentavalentdimercapto succinic acid (99mTc(V)-DMSA) as an effective agent diagnosing acute bone and joint infection [1]. We now report that 99mTc(V)-DMSA can identify foci of infection in a case of fever of unknown origin. 99mTc(V)-DMSA, as a tumo...

Background: Multiple Myeloma (MM) is a B cell neoplasm causing lytic or osteopenic bone abnormalities. Whole body skeletal survey (WBSS), Magnetic resonance (MR) and 18F-FDG PET/CT are imaging techniques routinely used for the evaluation of bone involvement in MM patients. Aim: As MM bone lesions may present low 18F-FDG uptake; the aim of this study was to assess the possible added value and li...

Meningiomas with distant metastases rarely occur. We report a patient with coincident primary lung cancer and metastatic meningiomas. The presence of distinct imaging features and a differential response to chemotherapy enabled us to distinguish the primary lung cancer from the metastatic lesions. Previous studies suggest that several factors can enhance the propensity of meningioma for metasta...

Background Treatment of patients with Takayasu arteritis (TAK) is challenging in-spite the use conventional cytotoxic agents and biologics. Tofacitinib has been reported to be effective in inducing maintaining remission around 80% refractory TAK [1]. Objectives To assess efficacy safety tofacitinib Indian TAK. Methods In this retrospective study, medical records consecutive being treated either...

Malignant pleural mesothelioma (MPM) is an uncommon neoplasm arising from mesothelial cells of the pleura and less commonly of the pericardium or peritoneum. The annual incidence of 3000 cases is expected to increase by more than 50% in the coming decade due to the patterns of occupational exposure to asbestos and latency period of 30–40 years [1,2]. Treatment options depend on stage at present...

Treglia et al. [1] have recently proposed a meta-analysis evaluating the diagnostic performance of 99mTc-MIBI scan in predicting the malignancy of thyroid nodules. 99m-Tc is registered and adopted worldwide for myocardial perfusion imaging and for the diagnostic work-up of hyperparathyroidism. Furthermore there are reports on the use of 99mTc-MIBI imaging in post-surgical evaluation of thyroid ...
