Chronic fatigue syndrome (CFS) has been widely studied by neuroimaging techniques in recent years with conflicting results. In particular, using single-photon emission computed tomography (SPECT) and perfusion tracers, hypoperfusion has been found in several brain regions, although the findings vary across research centers. The objective of this study was(More)
OBJECTIVE The purpose of this study was to assess the prognostic value of (18)F-FDG PET performed at restaging in patients with locally advanced rectal cancer who previously underwent neoadjuvant radiochemotherapy. SUBJECTS AND METHODS Eighty-eight patients with histologically proven rectal cancer classified at clinical TNM stages II and III were(More)
The differential diagnosis between benign and malignant pancreatic cystic lesions may be very difficult. We recently found that F-18-.uorodeoxyglucose positron emission tomography (18-FDG PET) was useful for the preoperative work-up of pancreatic cystic lesions. This study was undertaken to confirm these results. From February 2000 to July 2003, 50 patients(More)
OBJECTIVE To assess the reliability of 18-fluorodeoxyglucose positron emission tomography (18-FDG PET) in distinguishing benign from malignant cystic lesions of the pancreas. SUMMARY BACKGROUND DATA The preoperative differential diagnosis of cystic lesions of the pancreas remains difficult: the most important point is to identify malignant or premalignant(More)
OBJECTIVE To assess the reliability of 18-fluorodeoxyglucose positron emission tomography (18-FDG PET) in distinguishing benign from malignant intraductal papillary mucinous neoplasms (IPMNs) of the pancreas and its contribution to surgical decision making. SUMMARY BACKGROUND DATA Pancreatic IPMNs are increasingly recognized, often as incidental findings,(More)
BACKGROUND The outcome after treatment for glioblastoma remains poor. Therefore, the authors evaluated the long term efficacy and toxicity of treatment with radiotherapy and concurrent carboplatin plus teniposide followed by three cycles of carmustine in patients who underwent resection for glioblastoma. METHODS Fifty-six newly diagnosed patients with(More)
Many patients with Alzheimer's disease (AD) develop parkinsonian symptoms, suggesting an overlapping between AD and Parkinson's disease (PD). However, pathologic and neurochemical studies indicate that the involvement of the dopamine system may be different in the two conditions. Using single photon emission tomography, we determined the relative specific(More)
The prediction of survival of patients with pancreatic cancer is usually based on tumor staging and grading and on the level of tumor markers. However, accurate tumor staging can be obtained only after resection, and still there is a great difference in survival rates among patients with the same clinicopathologic parameters. Recently the uptake of(More)
BACKGROUND Treatment of both Hodgkin's disease (HD) and aggressive non-Hodgkin's lymphoma (NHL) with abdominal presentation at the time of diagnosis is often followed by detection of residual masses by computed tomography (CT). However, CT is usually unable to discriminate between residual tumor and fibrosis/necrosis. We investigated the ability of(More)
OBJECTIVE To assess the reliability of the International Consensus Guidelines (ICG) and 18-fluorodeoxyglucose positron emission tomography (PET) in distinguishing benign from malignant intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. BACKGROUND Since 2006 the ICG have been used to choose immediate surgery or surveillance for IPMN(More)
