Various treatment options for cancer including novel molecularly targeted cancer treatments are available. However, the appropriate selection of methods for evaluation of therapeutic efficiency is crucial for effective cancer treatment. The purposes of this exhibit are: 1. To learn multi-tracer PET/CT or PET/MRI imaging for tumors. 2. To learn assessment of therapeutic response of various tumors. The major teaching point of this exhibit are: 1. It is necessary to select a optimal tracer for the drug used, especially for molecular-targeted drugs. 2. The appropriate method for posttreatment PET evaluation can lead to better management of cancer patients for prolonged survival and for preserving quality of life.

1. PET tracers used for the evaluation of anti-tumor therapy: 18F-flurodeoxyglucose (FDG), 18F-fluroethyltyrosine (FET), 18F-3'-deoxy-3'-18F-fluorothymidine (FLT), Glycosylated arginine-glycine-aspartic acid peptide (Galacto-RGD), 18F-fluciclatide, 11C-methionine, and Radioactive water (H215O) 2. Therapeutic response imaging for various tumors: with reviewing clinical cases - Brain tumors, Lung cancer, Esophageal cancer, Breast cancer, and Lymphoma 3. Evaluation methods: Texture analysis, and PET Response Criteria in Solid Tumors (PERCIST)
