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...

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...

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...

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 diagnosis of alzheimer disease ‎underwent 18f-fdg pet and ‎99mtc-...

An inflammatory pseudotumor (IPT) is a rare benign lesion, characterized by nonneoplastic proliferation of inflammatory cells and presence of intermingling collagen fibers. IPT commonly occurs in the lungs and orbita, while an intraspinal IPT is extremely rare. IPT can mimic both clinically and radiologically malignant processes, and making a definitive preoperative diagnosis is often difficult...

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...

BACKGROUND Combined positron emission tomography (PET) and computed tomography (CT) can assess both anatomy and biology of carotid atherosclerosis. We sought to assess whether 18F-fluoride or 18F-fluorodeoxyglucose can identify culprit and high-risk carotid plaque. METHODS AND RESULTS We performed 18F-fluoride and 18F-fluorodeoxyglucose PET/CT in 26 patients after recent transient ischemic at...
