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?

A 52-year-old female patient proved histopathologically to have adenocarcinoma (AC) involving the left upper lobe. A (coronal PET), B (coronal PET/CT), C (axial CT in a mediastinal window), D (axial CT in a lung window), E and F images (axial PET/CT images). The mass lesion size measured in the C image was 4.56 cm with SUVmax of the tumor was 3.99 as shown in E. TLR was calculated to be 3.99/3.72 = 1.07
