^a(Patient no. 24) A patient with small hypovascular lesions in the bilateral kidney on CECT; the FDG-PET/CT findings could not be assessed due to physiological uptake by the renal parenchyma. This patient was treated for IgG4-RD
^b(Patient no. 30) A patient with abnormal pancreas findings on CECT, without significant abnormal FDG uptake. The patient was diagnosed as having autoimmune pancreatitis using endoscopic retrograde cholangiopancreatography
