18F-FDG PET/CT for Surveillance in Salivary Gland Cancers: A Systematic Review and Meta-Analysis.
Laryngoscope
January 2025
Department of Otolaryngology-Head and Neck Surgery, McGill University, Montreal, Quebec, Canada.
Objective: To evaluate the diagnostic accuracy of 18F-FDG-PET/CT compared to conventional imaging modalities (CIM) to detect recurrence of primary salivary gland cancers (SGCs).
Data Sources: Review performed on December 26, 2024, using Embase, CINHAL, MEDLINE, and PubMed.
Review Methods: Two blinded reviewers selected studies reporting diagnostic accuracy of PET/CT in identifying locoregional recurrence and/or metastasis in patients with SGCs.
Atrial arrhythmias with mediastinal lymphadenopathy presentation of isolated atrial myocarditis.

Department of Electrophysiology, Department of Cardiology AIG Institute of Cardiac Sciences and Research Hyderabad India.
Objectives: We present a case series of patients with granulomatous myocarditis presenting as atrial arrhythmias accompanied by lymphadenopathy.
Background: Atrial myocarditis (AM) may be the cause of atrial fibrillation (AF) in patients without risk factors.
Methods: Patients with atrial fibrillation without risk factors underwent 18F-Fluorodeoxyglucose positron emission tomography (18F-FDG-PET).
Effectiveness of Data-Driven Gating FDG PET/CT for Abdominal Region.

Department of Nuclear Medicine, Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan.
This study aimed to validate the effectiveness of MotionFree (MF) in the abdominal region using 2 different PET/CT scanners to determine how to use MF efficiently. All 198 patients underwent respiratory-gated F-FDG PET/CT with MF. Imaging was performed using Discovery MI (DMI) and Discovery IQ (DIQ) PET/CT scanners, and all data were divided into 2 groups in each category (abdominal: upper and lower abdomen, lesion size, <20 mm and ≥20 mm; scanner group: DMI and DIQ).

Department of Medical Imaging, Montreal Heart Institute, Montréal, Québec, Canada.
Purpose Of Review: This review aims to explore the clinical significance of atrial fluorodeoxyglucose (FDG) uptake observed in positron emission tomography (PET) scans, focusing on its association with atrial fibrillation (AF), cardiac sarcoidosis, and myocarditis. We discuss the implications of atrial uptake for patient management and prognosis.
Recent Findings: Recent studies have demonstrated that atrial FDG uptake is frequently present in patients with AF, particularly those with persistent AF, and is linked to increased risks of stroke and poorer outcomes after ablation.
F-FAPI-42 PET/CT and F-FDG PET/CT in Patients with Malignant Digestive System Neoplasms: A Head-to-Head Comparative Study.

Department of Nuclear Medicine, the Second Affiliated Hospital, Guangzhou Medical University, Guangzhou, 510260, China.
Purpose: Radionuclide-labeled fibroblast activation protein inhibitor (FAPI) is an emerging tumor tracer. We sought to assess the uptake and diagnostic performance of F-FAPI-42 PET/CT compared with simultaneous 2-deoxy-2[F]fluoro-D-glucose (F-FDG) PET/CT in primary and metastatic lesions in patients with malignant digestive system neoplasms and to determine the potential clinical benefit.
Procedures: Forty-two patients (men = 30, women = 12, mean age = 56.
