The Deauville score has a total of five points. The five-point Deauville score is based on the measurement of lesion SUVmax, which is only compared with the liver and mediastinal SUVmax of the current imaging, without the need for strict baseline control, so the clinical application is simple and easy to master. The application of Deauville’s five-point scale has good inter-observer agreement during the assessment of the full course of efficacy in patients with Hodgkin’s lymphoma, DLBCL, and follicular lymphoma. Score 1.1: complete remission and disappearance of the tumor as revealed by imaging, no tumor activity shown under imaging, as well as no uptake of contrast by the tumor, and complete disappearance of all lesions. Score 2.2: usually shows complete remission of the condition of the visceral and mediastinal lesions, and complete disappearance of all lesions. 3.3 points: partial remission and partial disappearance of lesions in the mediastinum as well as most of the internal organs, such as the liver. 4.4 points: the condition is generally stable, but there is some uptake of contrast media by the organs of the liver and viscera, the condition is not completely controlled, and the lesions are between complete disappearance and addition. 5.5 points: the disease is in a progressive stage, the tumor continues to grow and expand, and the concentration of the ingested contrast agent has increased, and new foci may appear or the original foci have increased in size by more than 50%. Generally, the higher the score, the more serious the disease is. 1 and 2 points of lymphoma patients have better treatment effect, 3 points have better treatment effect, while 4 and 5 points have worse treatment effect. Specific scores need to be analyzed according to the examination of professional doctors.
