Retroperitoneal fibrosis is an uncommon disease characterized by inflammatory fibrosis typically surrounding abdominal aorta and iliac arteries. The glucose analogue F18-fluorodeoxyglucose can be used to image inflammatory cell activity non-invasively by PET. In this report we investigated the usefulness of the FDG PET/CT in the disease activity and therapy response evaluation of retroperitonea...
Abstract This observational study was conducted owing to the challenges of positron emission tomography/magnetic resonance imaging (PET/MRI) that requires longer duration scanning radiopharmaceutical injected patient and added MRI environment. The aim this assess radiation dose at different distances from burden anesthesiologist other personnel in performing PET/MRI under general anesthesia or ...
Abstract Background The purpose of this study is to assess brain glucose metabolism and Amyloid‐β burden in patients with Alzheimer’s disease 3 Tesla PET/MR imaging seek possible relation findings the extent cognitive impairment. Method 45 consecutive subjects memory complaints were evaluated a detailed neuropsychological test battery F18‐Fluorodeoxyglucose(FDG)‐PET/MRI F18‐Flutemetamol‐PET/MRI...
We investigated sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 18F-fluorodeoxyglucose-positron emission tomography in 170 cases with suspected or biopsy-proven posttransplant lymphoproliferative disorder. All solid organ and hematopoietic stem cell transplant recipients who underwent an 18F-fluorodeoxyglucose-positron emission tomography scan betw...
INTRODUCTION Diagnosis of Takayasu's arteritis as the cause of stroke is often delayed because of non-specific clinical presentation. F-18-fluorodeoxyglucose positron emission tomography-computed tomography may help to accurately diagnose and monitor Takayasu's arteritis in stroke patients. CASE PRESENTATION We report the case of a left middle cerebral artery stroke in a 39-year-old man. Labo...
OBJECTIVE Fluorodeoxyglucose positron emission tomography/computed tomography imaging in the follow-up of patients with differentiated thyroid carcinoma who have high serum thyroglobulin, negative iodine-131 whole body scan and suppressed thyrotropin. PATIENTS AND METHODS A total of 90 patients (31 male and 59 female) with differentiated thyroid carcinoma who have high serum thyroglobulin and...
BACKGROUND The aim of this study was to evaluate the success of selective intraarterial radionuclide therapy (SIRT) with Yttrium-90 (Y-90) microspheres in liver metastases of different tumors. We also interpreted the contribution of SIRT to survival times according to responder- non responder and hepatic- extra hepatic disease. METHODS The clinical and follow-up data of 124 patients who were ...
INTRODUCTION Molecular imaging of the spine is a rarely used diagnostic method for which only a few case reports exist in the literature. Here, to the best of our knowledge we present the first case of a combination of molecular imaging by single photon emission computer tomography and positron emission tomography used in post-operative spinal diagnostic assessment. CASE PRESENTATION We prese...
Introduction: Although the association between cancer and sarcoidosis or sarcoid reaction is known, sarcoid reaction associated with Merkel cell carcinoma is rare. Case presentation: We report the case of a 57-year-old Japanese woman with Merkel cell carcinoma in the inguinal area associated with sarcoid reaction. Fluorodeoxyglucose positron emission tomography demonstrated elevated fluorodeoxy...
