The clinical added-value of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (18FDG PET) in the management of oncology patients is increasingly documented. In the present review, we discuss both the benefits and the limitations of 18FDG PET in different cancers. Considering the literature data and our own experience, we also indicate the best clinical approach to optimize the use of me...
زمینه: در تصویربرداری پت، فلوئور-18 بهترین رادیونوکلید می‌باشد. نشاندار سازی پپتید به طور مستقیم با فلوئور-18 مشکل است و از روش غیرمستقیم و استفاده از ترکیبات واسطه حاوی فلوئور-18 استفاده می‌شود. به دلیل در دسترس بودن 18FDG در اغلب مراکز پت، 18FDG به عنوان یک ترکیب واسطه از پتانسیل بالائی برای نشاندار کردن پپتیدها برخوردار می‌باشد. در مطالعه حاضر یک پپتید خطی حاوی گروه آمینواکسی برای تصویربردار...
DCE-MRI provides information about the perfusion of tumours together with morphological details. Perfusion of tumour could be assessed by dynamic 18FDG PET/CT (dFDG/PET), in addition to metabolic information. This study was planned to compare the semi-quantitative parameters of DCE-MRI) and dFDG/PET in locally advanced breast cancer. Forty patients with LABC underwent DCE-MRI and DFDG/PET study...
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...
We audited whether 18F-Fluorodeoxyglucose positron emission tomography-computed tomography (18FDG PET-CT) imaging could discriminate between different diagnoses in HIV-infected patients presenting with lymphadenopathy, with or without fever and/or splenomegaly. Maximum standardised uptake (SUVmax) values were similar in lymphoma and mycobacterial and fungal infections and were lower but similar...
Basal cell adenoma is an uncommon benign salivary gland neoplasm, presenting isomorphic basaloid cells with a prominent basal cell layer. Basal cell adenoma arising from the nasal septum is exceptionally rare. Reports on positron emission tomography with 2-deoxy-2-fluorine-18-fluoro-D-glucose (18FDG-PET) imaging for basal cell adenoma are limited. Here, we present the case of a 49-year-old man ...
BACKGROUND Thyroid incidentaloma is defined as an unsuspected thyroid lesion found on imaging study or while performing a surgery non-related to the thyroid gland. Most recent scientific literature tends to demonstrate a detection rate of 0.1-4.3% for incidental findings of thyroid focal uptake identified by 18F-fluorodeoxyglugose Positron Emission Tomography with computed tomography (18FDG-PET...
BACKGROUND Subjects with amnesic mild cognitive impairment (aMCI) may include patients at high risk for progression to Alzheimer disease (AD) and a population with different underlying pathologic conditions. OBJECTIVE To evaluate the potential roles of positron emission tomography with fluorodeoxyglucose F 18 (18FDG-PET) and memory scores in identifying subjects with aMCI and in predicting pr...
OBJECTIVE To determine the contribution of 18FDG PET, 11C-flumazenil PET, and 123I-iomazenil SPECT to the presurgical evaluation of patients with medically intractable complex partial seizures. METHODS Presurgical evaluation was performed in 23 patients, who were considered candidates for temporal lobe resective surgery (14 females and nine males with a median age of 34 (range 13 to 50) years...
