The Value of 18F-FDG PET/CT Mathematical Prediction Model in Diagnosis of Solitary Pulmonary Nodules
Figure 5
A false-negative PET/CT finding in a 64-year-old female patient. (a) On CT image, the nodule in the right upper lobe with lobulation and low density is observed (arrow); the maximum diameter of nodule is 17 mm. (b) On PET and (c) on PET/CT image, increased 18F-FDG uptake is detected; = 7.4; the result of PET imaging is infection. (d) Pathologic examination suggests metastatic adenocarcinoma. The value calculated by our model is 0.73. The result of our model is consistent with PET and pathological result but inconsistent with PET/CT.
