The infection group presented a higher bp-SUVr (4.63 ± 1.68) compared to neoplasia (4.38 ± 1.89) and other conditions (3.43 ± 2.19), while CRP levels were distinctly elevated in infection (15.29 ± 4.11 mg/L) vs. neoplasia (4.86 ± 1.56 mg/L) and other (4.43 ± 3.21 mg/L). This evidence concerns the gene CRP and infection.
