100 cases of lymphoma patients are enrolled in this study. Participation in this study involves three dynamic 18F-FDG PET/CT exams, which occur before the treatments start, two or three days before the fourth cycle of chemotherapy, and then six weeks after the end of last treatments. Progress Free Survival(PFS) and Overall Survival(OS) are used as the end points to study the value of metabolic parameters obtained from the dynamic PET/CT imaging. The differences of dynamic metabolic parameters and static SUV value are evaluated in patients with lymphoma from the perspective of diagnosis, staging, treatment and prognosis.
The prospective study aims to explore the value of total-body PET/CT dynamic imaging (uExplorer) in assessing the treatments and prognosis in patients affected with lymphoma. Total-body 18F-FDG PET/CT scans are being performed before treatment, after three cycles of chemotherapy and six weeks after the end of treatment. The plan of this study involves to evaluate the clinical application of total-body PET / CT in patients histopathologically-diagnosed as lymphoma, and to optimize the dynamic acquisition protocols with total-body 18F-FDG PET/CT.
