BACKGROUND Fluorine-18 fluoroethoxybenzovesamicol ([18F]FEOBV) is a radioligand for the selective imaging of the vesicular acetylcholine transporter with positron emission tomography (PET). The current study demonstrates that pathological cortical cholinergic deafferentation can be quantified in vivo with [18F]FEOBV PET, yielding analogous results to postmortem histological techniques. METHOD...

A 53-year-old man with a history of nausea and elevated liver functions presented to our clinic. A CT scan showed a small tumor in the right lobe of the liver. Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography confirm abnormal metabolic activity with a high standardized uptake value of 7.3 in the lesion. These findings could indicate a malignancy such as well-differentiated ...

objective(s): the study objective was to assess the diagnostic performance of positron emission tomography (pet) for gliomas using the novel tracer 18f-fluciclovine (anti-[18f]facbc) and to evaluate the safety of this tracer in patients with clinically suspected gliomas.methods: anti-[18f]facbc was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by pet...

To further develop gene therapy for patients with glioblastomas, an experimental gene therapy protocol was established comprising a series of imaging parameters for (i) noninvasive assessment of viable target tissue followed by (ii) targeted application of herpes simplex virus type 1 (HSV-1) amplicon vectors and (iii) quantification of treatment effects by imaging. We show that viable target ti...

Background: The most prevalent hematological malignancy, malignant lymphoma, makes up around 8% of all adult malignancies. Non-Hodgkin lymphoma (NHL) and Hodgkin disorder (HD) are two types lymphoid neoplasms. Aim the Work: Examine how PET/CT may be used to diagnose nodal lymphoma. Analyze effectiveness (18 FDG PET/CT) in first staging function PET-CT patient monitoring both during after therap...

BACKGROUND Cancer of unknown primary (CUP) is a heterogeneous group of cancers, so called when a biopsy from a patient reveals malignancy without giving a clue to where in the body the primary tumor is located. Whole-body 18-fluorine-fluorodeoxyglucose positron-emission-tomography/computed tomography (18F-FDG PET/CT) is widely used for diagnosis and staging of most cancers. We hypothesized that...

Abstract Background 8–28% of patients infected with COVID-19 have evidence cardiac injury, and this is associated an adverse prognosis. The cardiovascular mechanisms injury are poorly understood speculative. We aim to use multimodality imaging including magnetic resonance (CMR) imaging, computed tomography coronary angiography (CTCA) positron emission 2-deoxy-2-[fluorine-18]fluoro- d -glucose i...

Abstract Urethral melanomas are a rare subtype of noncutaneous melanomas. The disease has tendency to have skip lesions and early metastases as compared with cutaneous role fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography computed (PET-CT) is well established in cases recommended by the National Comprehensive Cancer Network (NCCN) for stage IIB IV cancer. There no guideline...

UNLABELLED Chemotherapy is currently the treatment of choice for patients with high-risk metastatic breast cancer. Clinical response is determined after several cycles of chemotherapy by changes in tumor size as assessed by conventional imaging procedures including CT, MRI, plain film radiography, or ultrasound. The aim of this study was to evaluate the use of sequential 18F-FDG PET to predict ...

Mouse models of Alzheimer's disease (AD) are valuable but do not fully recapitulate human AD pathology, such as spontaneous Tau fibril accumulation and neuronal loss, necessitating the development new models. The transgenic (TG) TgF344-AD rat has been reported to develop age-dependent features including loss neurofibrillary tangles, despite only expressing APP PSEN1 mutations, suggesting an imp...
