The Value of ¹⁸F-FDG PET/CT Mathematical Prediction Model in Diagnosis of Solitary Pulmonary Nodules

Figure 6

A typical PET/CT finding in a 56-year-old male patient. (a) On CT image, the nodule in the left upper lobe with high density in the center and low density in the surrounding tissue and a clear border is observed (arrow); the maximum diameter of nodule is 22 mm. (b) On PET and (c) on PET/CT image, = 1.7. (d) Pathologic examination suggests bronchioloalveolar carcinoma. The value calculated by our model is 0.09. The result of our model is inconsistent with PET/CT and pathologic result.
