Figure 4. Spearman’s rank correlation of SUVmax values with CRP (mg/dL). (A) All cases (n = 105). Sixteen non-renal cancer lesions with higher FDG uptake than renal cancer lesions were identified, as indicated by black circles; (B) All cases (n = 89), excluding 16 cases where FDG uptake was higher in non-cancerous renal tissues than in RCC lesions. SUVmax: Maximum standardized uptake value; CRP: C-reactive protein; FDG: ¹⁸F-fluorodeoxyglucose.
