Prediction of Chemotherapy Response of Osteosarcoma Using Baseline 18F-FDG Textural Features Machine Learning Approaches with PCA

Figure 1

Representative 18F-FDG PET images of a responder and a nonresponder with osteosarcoma. Responder SUVmax values were 11.33 and 4.43 at baseline and after neoadjuvant chemotherapy (NAC), respectively. Nonresponders had SUVmax values of 5.62 and 3.21 at baseline and after NAC, respectively.
