We present the imaging findings of a 77-year-old man with a history of malignant cutis melanoma that metastasized to the gallbladder. A restaging 18 F-FDG PET/CT scan showed uneven thickening and elevated 18 F-FDG uptake in the gallbladder wall. Subsequently, the patient underwent laparoscopic cholecystectomy, and histopathologic findings confirmed the diagnosis of metastatic melanoma of the gallbladder.

Purpose: This meta-analysis aims to compare the diagnostic efficacy of [F]FDG PET/CT and [F]FDG PET/MRI in patients with non-small cell lung cancer (NSCLC).
Methods: An extensive literature search was conducted throughout the PubMed, Embase, and Web of Science databases for works accessible through September 2024. We included studies assessed the diagnostic efficacy of [F]FDG PET/CT and [F]FDG PET/MRI in NSCLC.

Purpose: To investigate the prognostic value of post-chemoradiotherapy 2-[F]FDG PET/CT in locally advanced nasopharyngeal carcinoma (LANPC) and develop an accurate prognostic model based on the 2-[F]FDG PET/CT results.
Methods: 900 LANPC patients who underwent pretreatment and post-chemoradiotherapy 2-[F]FDG PET/CT from May 2014 to August 2022 were included in the study. We divided the patients into two distinct cohorts for the purpose of our study: a training cohort comprising 506 individuals, included from May 2008 to April 2020, and a validation cohort consisting of 394 individuals, included from May 2020 to August 2022.

This retrospective multicenter study investigated the biodistribution of Fluorodeoxyglucose (F-FDG) in the positron emission tomography (PET)/computed tomography (CT) in digital PET/CT (dPET) compared to analog PET/CT (aPET), focusing differences in physiological uptake in reference and small structures across various scanner models. One hundred thirty patients with similar preimaging conditions underwent both dPET and aPET imaging within 6 months. Visual evaluations and paired comparative analyses of semiquantitative parameters were performed for small and reference structures.

To establish and validate a nomogram based on clinical characteristics and metabolic parameters derived from F-fluorodeoxyglucose positron emission tomography and computed tomography (F-FDG PET/CT) for prediction of high-grade patterns (HGP) in invasive lung adenocarcinoma. The clinical and PET/CT image data of 311 patients who were confirmed invasive lung adenocarcinoma and underwent pre-treatment F-FDG PET/CT scan in Beijing Hospital between October 2017 and March 2022 were retrospectively collected. The enrolled patients were divided into HGP group (196 patients) and non-HGP group (115 patients) according to the presence and absence of HGP.

Materials And Methods: This retrospective study included 109 patients who underwent US-guided omental biopsies between June 2020 and June 2024. Pre-biopsy diagnostic images (CT, MRI, or [18 F]FDG PET/CT) were reviewed.
