We present a new case with FDG PET/CT images showing low FDG uptake in the nasopharynx plasmacytoma. Clinicians should be aware of this phenomenon and the potential for false negatives on FDG PET/CT.doi:10.1097/rlu.0b013e31821a2ae7Dong, Meng-jie...
Identifiable focal F-18 FDG uptake has been reported in high-grade mucoepidermoid carcinoma, but it is unclear whether F-18 FDG accumulates in low-grade mucoepidermoid carcinoma. Here, we present the case of a 37-year-old woman, with pathologically proven low-grade mucoepidermoid carcinoma, who ...
The majority of thymic cysts in our study showed FDG uptake equal to or lower than that of the mediastinum, resulting in a statistically significant difference in comparison with low-risk thymoma, and a PET visual grade cut-off value of two was adopted. Although thymic cysts typically show ...
known as lymphoma cells, within follicles, or nodules, that can accumulate in the lymphatic system and various tissues throughout the body. FL development is heterogenous and evaluated based on histological grade (1, 2, 3a, 3b) and stage (I, II, III...
It has previously been shown that fluciclovine demonstrates little accumulation in granulocytes/macrophages and comparable uptake to FDG in T and B cells [34]. Thus, T/B cell uptake may result in false-positive fluciclovine uptake in this sample set, and future studies will need to be ...
The aim of this observational study was to present a cohort of patients with high FDG uptake in BAT who underwent a second scan after receiving a low dose of propranolol, to determine whether the use of this premedication could improve the diagnostic confidence of FDG-PET scans by inhibition ...
·儿科影像学·18F-FDGPET/CT儿童脑肿瘤高低级别诊断吴书其,李瑾,陈素芸,马超,傅宏亮,李佳宁,邹仁建,王辉【摘要】 目的:探讨18F-FDGPET/CT对儿童脑肿瘤高低级别诊断的价值。方法:回顾性分析19例脑肿瘤患儿(男10例,女9例,平均年龄2.13岁)术前PET/CT影像学表现。所有病例均经手术病理证实。图像分析分别按目测法...
both mice and humans. Excellent tumor-to-background contrast was achieved in the chick CAM, which followed the same pattern of uptake in mice.18F-FDG tumor uptake in ovo, however, was consistently higher than in vivo. This variation could be explained by slower18F-FDG blood clearance in the...
Growth of a solitary pulmonary nodule after 6years diagnosed as oncocytic carcinoid tumour with a high 18-fluorodeoxyglucose (18F-FDG) uptake in positron e... Introduction: Pulmonary carcinoid tumour is low-grade neuroendocrine malignancy that is seen 1%2% of all lung neoplasms. Oncocytic carcinoid ...
Thus, FDG-PET/CT scans are planned at baseline and on day 11 (+/- 2) in patients enrolled in phase II study, to validate the ability of early metabolic change to predict TRG and outcome. For each tumor volume, maximal standardized uptake value (SUV-max, the maximum pixel value in the...
