In mouse models of dengue virus (DENV) infection, F-FDG PET is able to sensitively detect tissue-specific sites of inflammation and disease activity, as well as track therapeutic response to anti- DENV agents. However, the use of F-FDG PET to study the pathogenesis of inflammation and disease activity in DENV infection in humans, has not been clinically validated. Here we report the F-FDG PET imaging results of two patients during the febrile phase of acute DENV infection, paired with serial serum viral load, NS1 and proinflammatory cytokine measurements. Our findings demonstrate that F-FDG PET is able to sensitively detect and quantify organ-specific inflammation in the lymph nodes and spleen, in classic acute dengue fever. This raises the potential for F-FDG PET to be used as a research tool that may provide further insights into disease pathogenesis.

Background/aim: Angiogenesis imaging has been a valuable complement to metabolic imaging with 2-deoxy-2-[F]fluoroglucose (FDG). In our longitudinal study, we investigated the tumour heterogeneity and the relationship between FDG and [Ga]Ga-NODAGA-c(RGDfK) (RGD) accumulation in breast cancer xenografts.
Materials And Methods: Two groups of cell lines, a fast-growing (4T1) and a slow-growing cell line (MDA-MB-HER2+), were inoculated into SCID mice.

Background/aim: The present study aimed to assess the relationship between the maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography computed tomography (F-FDG-PET/CT) and the geriatric nutritional risk index (GNRI) in patients with soft-tissue sarcomas (STSs).
Patients And Methods: The present single-center retrospective observational study included patients who underwent F-FDG-PET/CT and for whom serum albumin levels, height, and body weight were measured prior to therapeutic intervention.
Results: A total of 81 patients were included in the study.

Hidradenocarcinoma (HAC) is a rare neoplasm that typically occurs in the head and neck region but seldom affects the chest wall. Histopathology and immunohistochemistry remain essential for diagnosing HAC, although their clinical utility in determining metastasis can be limited. Given the pathological rarity and histopathological heterogeneity of HAC, we report a case demonstrating the utility of positron emission tomography/computed tomography (PET/CT) combined with immunohistochemical examination for the accurate diagnosis and staging of HAC.

Background: The aim of this study is to develop deep learning models based on F-fluorodeoxyglucose positron emission tomography/computed tomographic (F-FDG PET/CT) images for predicting individual epidermal growth factor receptor () mutation status in lung adenocarcinoma (LUAD).
Methods: We enrolled 430 patients with non-small-cell lung cancer from two institutions in this study. The advanced Inception V3 model to predict EGFR mutations based on PET/CT images and developed CT, PET, and PET + CT models was used.
