Mediastinal lymph nodes were detected on a fluorine-18 (F-18) fluorodeoxyglucose (FDG), positron emission tomography (PET)/computed tomography (CT) scan (Siemens LSO HI-REZ Biograph 6; Siemens Medical Systems, Munich, Germany) in a 62-year-old man who presented with a large mass in the right upper lobe seen on coronal multiplanar reformatted image (Fig 1A).
Multiplanar reformation of images were constituted from PET/CT reoriented axial slices using the sagittal view as the reference (Fig 1B), with an image thickness of 1 cm and a distance between the images of 1 cm (Fig 2), and 1 slice with 2-cm thickness of coronal image on Figure 1 in three-dimensional syngo postprocessing software (Siemens Medical Systems). The axial images are created head-to-feet because of the view of invasive staging procedures.
