Pretreatment fluorodeoxyglucose positron emission tomography and computed tomography scan (on the left) shows high-grade metabolic activity in both atrial walls, interatrial septum with extensive left atrial wall involvement, posttreatment scan (on the right) shows about 50% decrease in the metabolic activity along the right and left atrium

The study revealed high-grade (SUVmax 10) metabolic activity in both atrial walls and interatrial septum with extensive involvement of the left atrial wall [Figure 1]. The scan revealed 50% decrease in the metabolic activity along the right atrium and the left atrium, suggesting fairly good response in 1 month [Figures 1, 3, 4].
Top row shows delayed enhancement in the inferior part of interatrial septum, bottom row shows minimal enhancement in the basal interventricular septum (as marked)

The maximum intensity projection image of the chest, the top image (pretreatment) shows bilateral atrial wall uptake with absent left ventricular uptake and the bottom image (posttreatment) shows reduced atrial wall uptake with normal left ventricular uptake
