In this image the additional value of a\u00a0<sup>18<\/sup>F-fluorodeoxyglucose positron emission tomography\/computed tomography ([<sup>18<\/sup>F]FDG PET\/CT) scan to discriminate is demonstrated. This scan was requested to study dissemination of an infection in a 61-year-old male, who was admitted to the intensive care due to multiple organ failure. Figure\u00a0<a href=\"https:\/\/link.springer.com\/article\/10.1007\/s00134-024-07505-5#Fig1\">1<\/a>\u00a0shows normal physiological uptake in the myocardium (pink arrow), bilateral pleural effusion (white arrow), atelectasis with slightly elevated [<sup>18<\/sup>F]FDG uptake in the left lower lobe (orange arrow) and atelectasis with high [<sup>18<\/sup>F]FDG uptake in the right lower lobe (green arrow). The high [<sup>18<\/sup>F]FDG uptake is likely due to an infectious focus. This was confirmed by a subsequent positive sputum culture positive for Serratia marcescens, which confirmed the diagnosis of a ventilator associated pneumonia.<\/p>\n\n\n\n<p>The low-level [<sup>18<\/sup>F]FDG uptake noticed in atelectasis is associated with low grade inflammation and not with increased tissue density of the lung. The intensive [<sup>18<\/sup>F]FDG uptake in the right lower lobe of the lung indicates a much larger local inflammatory response most likely caused by an infection.\u00a0Ultimately, this image emphasizes the potential of [<sup>18<\/sup>F]FDG PET\/CT to differentiate between infectious and inflammatory pulmonary abnormalities in critically ill patients.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/media.springernature.com\/full\/springer-static\/image\/art%3A10.1007%2Fs00134-024-07505-5\/MediaObjects\/134_2024_7505_Fig1_HTML.png?as=webp\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>A<\/strong>&nbsp;Maximum Intensity Projection.&nbsp;<strong>B<\/strong>&nbsp;Transversal [<sup>18<\/sup>F]FDG PET image.&nbsp;<strong>C<\/strong>&nbsp;Transversal fusion image of [<sup>18<\/sup>F]FDG PET\/CT. \u03b1\u2009=\u20090.5.
