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

Figure 4

A false-positive PET/CT finding in a 55-year-old male patient. (a) On CT image, the nodule in the left lower lobe with lobulation, spiculation, and vacuole sign is observed (arrow); the maximum diameter of nodule is 18 mm. (b) On PET and (c) on PET/CT image, increased ¹⁸F-FDG uptake is detected; = 2.2. (d) Pathologic examination suggests cryptococcal infection. The value calculated by our model is 0.91. The result of our model is consistent with PET/CT.
