Factors relevant to atrial ¹⁸F-fluorodeoxyglucose uptake in atrial fibrillation.

ABSTRACT:

Background

This retrospective study was designed to explore the factors relevant to increased atrial ¹⁸F-fluorodeoxyglucose (FDG) uptake in patients with atrial fibrillation (AF) who had undergone routine whole-body positron emission tomography/computed tomography (PET/CT) imaging.

Methods and results

Forty-eight consecutive AF patients (32 persistent, 16 paroxysmal) were identified from our routine FDG PET/CT database. Twenty-two control subjects were selected to establish the normal range of FDG uptake (maximum standardized uptake value, SUV_max) in target tissues. A target-to-background ratio (TBR) was calculated to determine abnormal uptake in the atrium and atrial appendage (AA). Univariate comparisons and multivariate regression analyses were condu
