Deauville Criteria

It is important to note that the NCCN modified Deauville scores mostly rely on reassessment of initially avid sites and that the NCCN recommends FDG PET scans for initial staging and for evaluating residual masses at the end of treatment.

Score     PET/CT Scan Result         

1.  No uptake above background
2.  Uptake at an initial site that is less than or equal to mediastinum
3.  Uptake at an initial site that is greater than mediastinum but less than or equal to liver
4.  Uptake at an initial site that is moderately increased compared to the liver at any site
5a.  Uptake at an initial site that is markedly increased compared to the liver
5b.  Uptake markedly increased compared to the liver at any new site that is possibly related to lymphoma
X  New areas of uptake unlikely related to lymphoma

The Deauville score is used throughout the NCCN recommendations and an example of a recommendation flow chart is given below.

Example images:

Figure 1 - Deauville score 2- Images 1A and 1B show hepatic levels of activity while 1C and 1D show activity in the blood pool which is greater than activity in a residual right paratracheal node (arrows)

Figure 1 Deauville Score 2

Figure 2 - Deauville score 2. Images 2C and 2D show hepatic levels of activity while 1A and 1B show activity in the blood pool which is equal to activity in a residual mediastinal node (arrows)

Figure 2 Deauville Score 2

Figure 3 - Deauville score 5b- The images show markedly increased FDG activity in a new anterior mediastinal lesion which is likely related to the lymphoma
