18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG PET/CT) has recently been added as a major criterion in the European Society of Cardiology (ESC) 2015 infective endocarditis guidelines. PET/CT is currently used patients with suspected prosthetic valve and cardiac device-related endocarditis. However, value ESC classification clinical impact PET findings are unkno...

Introduction:Brain imaging with F-18 fluorodeoxyglucose (18F-FDG) positron ‎emission tomography or Tc-99m hexamethylpropyleneamine oxime (‎99mTc-HMPAO) SPECT is widely used for the evaluation of Alzheimer's ‎dementia (AD); we aim to assess superiority of one method over the ‎other. Methods: Twenty four patients with clinical diagnosi...

Background and Purpose. Several studies have evaluated the role of fluorine-18-fluorodeoxyglucose positron emission tomography and positron emission tomography/computed tomography (FDG-PET and PET/CT) in diagnosing and assessing disease activity in patients with retroperitoneal fibrosis (RF). The aim of our paper is to perform a literature review on this topic. Methods. Scientific articles that...

BACKGROUND Several factors contribute to the high mortality of pancreatic cancer, including limitations of diagnostic imaging. AIM To perform a meta-analysis to assess the diagnostic accuracy of Fluro-deoxy-glucose positron emission tomography with computed tomography compared with computed tomography alone. METHODS Articles were identified through a MEDLINE search and bibliography review. ...

HYPOTHESIS Positron emission tomography (PET) influences clinical management in the preoperative evaluation of patients with hepatic metastases from colorectal cancer. DESIGN Prospective cohort study. SETTING Academic tertiary care center. PATIENTS From January 1, 2000, through December 31, 2002, 71 consecutive patients referred with potentially resectable hepatic metastases based on conv...

abstract necrotizing sarcoid granulomatosis (nsg) is a rare disease which is classified in the spectrum of pulmonary angiitis and granulomatosis. it is a variant of sarcoidosis and differs from it histologically. diagnosis is based on the pathological features, but radiology may help in the differential diagnosis. it is characterized by alveolar infiltrates or parenchymal nodules in multidetect...

In the last decade, positron emission tomography (PET) myocardial perfusion imaging (MPI) has emerged as a valuable clinical tool for the management of patients with known or suspected coronary artery disease (CAD). Compared with singlephoton emission computed-tomography (SPECT), PET provides higher-quality images and superior diagnostic accuracy (1). Increased availability of PET scanners, Med...

A method for partial volume correction of positron emission tomography (PET) images is proposed. The method is based on combining information from PET and high resolution anatomical images. Two different algorithms fast wavelet transform and à trous were implemented in order to decompose the PET and high resolution images. Results obtained using several simulated images show a significant parti...

Primary cardiac osteosarcoma is a very rare malignancy with a high incidence of local recurrence and systemic metastasis, contributing to the poor prognosis. Radiological modalities are commonly used for the evaluation of cardiac masses. 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) positron emission tomography/computed tomography is a valuable whole-body imaging modality in ...

The aim of the present study was to investigate positron emission tomography (PET)/computed tomography (CT) and its applications for the diagnosis and treatment of bone tumors. The advantages and disadvantages of PET/CT were also evaluated and compared with other imaging methods and the prospects of PET/CT were discussed. The PubMed, Medline, Elsevier, Wanfang and China International Knowledge ...
