Background: PET scans using FDG and somatostatin receptor imaging agents have both been used to study neuroendocrine tumours. Most reports have documented the sensitivity and specificity of each radiopharmaceutical independently, and even suggested the superiority of one over the other for different grades of disease. Aim: The aim of this work was to develop a grading scheme that describes the ...
The greatest health problem in sub-Saharan Africa is the complex of HIV and TB. PET has been primarily developed to look at cancer but can PET be used for this major health problem. F-18FDG has a high sensitivity in TB but the pattern of uptake is not specific. Attempts to improve the specificity of F-18 FDG imaging in the context of TB by using dual time scanning has not proved useful. There i...
Background Nearly 40% of colorectal cancer (CRC) recurs within 2 years after resection of primary tumor. Imaging with fluorine-18-fluorodeoxyglucose (l8F-FDG) positron emission tomography/computed tomography (PET/CT) is the most recent modality and often applied for the evaluation of metastatic spread during the follow-up period. Our goal was to study the diagnostic importance of 18F-FDG-PET/CT...
PURPOSE The aim of this study was to evaluate the effect of combined (68)Ga and (18)F-FDG PET/CT on treatment management for patients with pancreatic neuroendocrine tumor (PNET). METHODS Between January 2012 and April 2014, 49 consecutive patients with a cytologically and/or histologically proven diagnosis of PNET underwent combined (68)Ga and (18)FDG PET/CT on the same day. RESULTS The stu...
OBJECTIVE Based on the results of a recently accomplished multicenter clinical trial for the incremental value of a dual-tracer (18F-FDG and 18F-FLT), dual-modality (PET and CT) imaging in the differential diagnosis of pulmonary lesions, we investigate some issues that might affect the image interpretation and result reporting. METHODS The images were read in two separate sessions. Firstly th...
PURPOSE Repeatability of baseline FDG-PET/CT measurements has not been tested in ovarian cancer. This dual-center, prospective study assessed variation in tumor 2[18F]fluoro-2-deoxy-D-glucose (FDG) uptake, tumor diameter, and tumor volume from sequential FDG-PET/CT and contrast-enhanced computed tomography (CECT) in patients with recurrent platinum-sensitive ovarian cancer. EXPERIMENTAL DESIG...
Results: CS was presented by ventricular tachycardia, total AV block, paroxysmal atrial fibrillation, persistent atrial flutter, complete right bundle branch block and multifocal PVC’s. Moderate diastolic dysfunction (DD) was detected on echocardiography in one patient and mild DD in two patients. Systemic sarcoidosis was histologically and/or cytologically confirmed in all patients. No endomyo...
