The Value of Diffuse Splenic and Hepatic ¹⁸F-FDG Uptake on PET/CT in Diagnosing Patients with Anemia

Figure 1

Four cases with different hemoglobin levels, from 56 g/L(A) to 136 g/L(D). The hemoglobin level decreased, as the splenic ¹⁸F-FDG uptake increased. The patient is male and 71 years old whose hemoglobin level is 136 g/(L). The spleen SUVmax and spleen SUVmean of this patient were 1.436 and 1.183, respectively (a). The patient is female and 42 years old whose hemoglobin level is 106 g/(L). The spleen SUVmax and spleen SUVmean were 1.993 and 1.656, respectively (b). The patient is female and 42 years old whose hemoglobin level is 77 g/(L). The spleen SUVmax and spleen SUVmean were 1.954 and 1.635, respectively (c). The patient is female and 52 years old whose hemoglobin level is 56 g/(L). The spleen SUVmax and spleen SUVmean were 2.16 and 1.787, respectively (d).
