The parameters of the SVM algorithm were optimized using the particle swarm optimization (PSO) algorithm. A total of 58 patients who were diagnosed with TN by PET\/CT at a hospital were divided into a group with benign nodules (group B, 25 cases) and a group with malignant nodules (group M, 33 cases). The characteristics of the PET-CT images and difference in the max standardized uptake value (SUVmax) of PET-CT were analyzed. The PPIR of RLN was calculated. It was found that when the number of iterations was 19, the fitness and the classification accuracy of the SVM algorithm was 98.3% and 91.1%, respectively. When SUVmax\u2009=\u20094.56, its sensitivity and specificity were 81.33% and 76.18%, respectively. The SUVmax of group B was much lower (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.01<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>).
