Figure 1.

Pre- and post-operative findings of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography. Before the immunosuppressive therapy (upper panels), an intense accumulation was detected at the apex of the right lung (red arrows) as well as the aortic root (yellow arrows). Since long-term fasting had not been performed for this study, the myocardial accumulation itself was considered a potentially physiological finding. The aortic root is magnified in the inset. After immunosuppressive therapy (lower panels) performed under 18-hour fasting with heparin injection, the disappearance of both abnormal accumulations was confirmed.
