Specific information of false-positive and false-negative cases according to the new index judgment of PTLD
The results of non-destructive PTLD diagnosis predicted by the cut-off value showed that there were three false negatives and one false positive. See TABLE 5 for specific results. The final diagnosis of the false-positive patient was reactive hyperplasia of the lymph nodes, but the SUVmaxBio was too high; so, it was misjudged as PTLD. The final diagnosis of the three false-negative cases was non-destructive PTLD, and their SUVmaxBio or SDL/LDL values were too low; so, they were misjudged as being PTLD-negative cases.
