Difference of PET metabolic parameters between M-HLH and NM-HLH. The SUVmax-LN/Sp/Li and SUVmean-Sp in M-HLH were significantly higher than those in NM-HLH () (a)–(c), and (g). There was no significant difference between the two groups between SUVmax-BM (e) and SUVmean-LN/Li/BM (d), (f), and (h). M-HLH: malignancy-associated HLH; NM-HLH: non-malignancy-associated HLH; SUVmax: maximum standard uptake value; SUVmean: mean standard uptake value; Sp: spleen; Li: liver; BM: bone marrow; LN: lymph nodes; M: mediastinum; and LiBG: liver background.
