From: FDG-PET/CT tumor to liver SUV ratio (TLR), tumor SUVmax, and tumor size: can this help in differentiating squamous cell carcinoma from adenocarcinoma of the lung?

Fig. 5

A 59-year-old male patient proved histopathologically to have squamous cell carcinoma (SCC) involving the left upper lobe. A (coronal PET), B (coronal PET/CT), C (coronal CT in a mediastinal window), D, E, and F images (axial PET/CT images). The mass lesion size measured in the C image was 10.1 cm with SUVmax of the tumor was 30.9 as shown in E. TLR was calculated to be 30.9/4.58 = 6.75. Para-esophageal (D) and Subcarinal (E) lymphadenopathies noted with SUVmax = 26.34 and 41.33, respectively
