INTRODUCTION (18)F-FDG-PET-CT plays an important role in the management of lymphoma postchemotherapy followup. Some centres perform prechemotherapy baseline CT and postchemotherapy PETCT. With a concern of radiation burden, especially in young patients, this study aimed to assess if PETCT radiation dose could be reduced. METHODS Retrospective analysis of 100 lymphoma patients was performed to...

Abstract Background Pancreatic neuroendocrine tumor (PNET) is a subgroup of (NET) that has unique biology and natural history. The histological classification major role in the management this pathology, but recent years Gallium 68 dotatate (68Ga-DOTA) scanning at center discussion about how these imaging technologies can modify clinical tumors their results are correlated to Ki67 index. Method...

Neurolymphomatosis (NLY) is a type of rare disease with poor prognosis, characterized by infiltration of nerves, nerve roots and plexus. We report a case of 54-years old female patient non-diabetic and normotensive diagnosed with chronic lymphocytic leukemia presented with pain in the neck and arm and numbness in the ipsilateral hand. The patient underwent 18F fluorodeoxyglucose PET/...

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...

Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...

Abstract Background With the expansion of use neoadjuvant chemotherapy(NAC) in locally advanced breast cancer (LABC), both dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) and 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET CT) are promising methods for assessment tumor response during chemotherapy. We aimed to evaluate diagnostic accuracy DCE-MRI &18 F-FDG PE...

Brain positron emission tomography (PET) has also been used over many years to diagnose neurodegenerative diseases, and has advantages over MRI due to its higher sensitivity to detect pathologies at a molecular level. While 18F-fluorodeoxyglucose (FDG) PETCT is an established imaging technique for assisting in the differential diagnosis of Alzheimer’s disease (AD) and other forms of dementia, P...
