Fig. 3E —56-year-old man with non–small cell lung cancer manifesting as left upper lobe mass. Attenuation correction performed using unenhanced CT (A–C) and IV contrast-enhanced CT (D–F). Coronal images show no perceived visual increase in ¹⁸F-FDG activity in mass (arrows) compared with A–C. Mean (maximum) SUV values of mass were 17.3 (24.6), an increase of 14.9% compared with A–C. Note ¹⁸F-FDG activity in contrast-enhanced right subclavian vein and heart is similar to A–C when unenhanced CT is used for attenuation correction. E, Attenuation-corrected PET with enhanced CT.
