Fig. 1From: The rim sign: FDG-PET/CT pattern of pulmonary infarctionA 55-year-old man with a metastatic right lower lobe lung adenocarcinoma (patient 1). FDG-PET/CT images showed a right upper lobe subpleural consolidation exhibiting the rim sign (a, axial PET; b, axial fusion, arrows). Metastatic mediastinal adenopathies were clearly visible (arrowheads). Combined enhanced MDCT confirmed the acute pulmonary embolism (c, arrow) and showed the vessel sign associated with the right pulmonary infarction (d, arrow)Back to article page
