Development and Validation of a <sup>18</sup>F-FDG PET/CT-Based Clinical Prediction Model for Estimating Malignancy in Solid Pulmonary Nodules Based on a Population With High Prevalence of Malignancy.
Metabolic information obtained through <sup>18</sup>F-flurodeoxyglucose positron emission tomography/computed tomography (<sup>18</sup>F-FDG PET/CT) is used to evaluate malignancy by calculating the glucose uptake rate, and these parameters play important roles in determining the prognosis of non-small cell lung cancer (NSCLC).
Our study group comprised 132 cancer patients (116 f, 16 m; mean age 50 ± 16 years) who underwent F18-FDG PET/CT per standard clinical protocol, for staging or surveillance of cancer.
Ninety-three patients with known primary tumors underwent whole-body hybrid FDG PET/MRI during the follow-up of their malignancies with the use of NCE and CE protocols.
F-FDG PET/CT was recommended for identifying potential malignancy and showed several hypermetabolic masses in the pancreas, left testis, and right lung.
We report a case with hamartoma of mature cardiac myocytes of the right auricle demonstrating intense F-FDG uptake and a large amount of pericardial effusion on PET/CT mimicking malignancy in a 41-year-old man.
An F-FDG PET/CT performed to rule out underlying malignancy revealed an intense diffuse and isolated muscular FDG uptake with fascia infiltration on the CT finding.
Our aim was to assess the effect of a Bayesian Penalised Likelihood (BPL) PET reconstruction on the assessment of SPN FDG uptake and estimation of malignancy risk (Herder score).
Here, we used <sup>18</sup>F-FDG PET/CT imaging to investigate whether artificial nutrition has an impact on tumour glucose metabolism in patients with cancer and cachexia.
Incidental thyroid uptake is found in approximately 2.5% of patients who undergo FDG PET for nonthyroid malignancy; approximately a third of the FDG PET thyroid incidentalomas are malignant, including primary thyroid malignancies and metastasis.
The study group comprised 142 patients (121 female, 21 male; mean age, 49 ± 16 years) who underwent F18-FDG PET/CT (PET/CT) for staging or surveillance of cancer and who were BAT-positive on PET/CT.
As well as in many others cancers, FDG uptake is correlated with the degree of malignancy in gliomas, that is, commonly high FDG uptake in high-grade gliomas.
Considering that most of these are 18F-FDG avid tumors and that the 18F-FDG PET/CT scan is often added to the diagnostic work-up when screening patients for malignancy, this functional imaging can play a decisive role.
To compare retrospectively fused FDG PET/CT and MRI (PET/MRI) to FDG PET/CT and MRI for characterisation of indeterminate focal liver lesions as malignant or benign in patients with a known primary malignancy.
