Abstract
Aim of the study
To compare [¹¹C] choline PET/CT findings between patients with cirrhosis and normal
liver controls.
Methods
Included 11 patients with cirrhosis and 14 controls. All underwent a dynamic [11C]
choline PET/CT. The maximal standard uptake values (SUVmax), the area under the curve
(AUC) and kinetic parameters (K1 and K2), clinical and laboratory data, were compared
between groups.
Results
Patients mean age was 68.4 ± 10.7 and controls, 69.7 ± 7.3 years. Mean SUVmax was
higher in patients than controls (right lobe, 10.06 ± 12 vs. 6.3 ± 1.6, P = 0.011; left lobe, 8.6 ± 11.6 vs. 5.4 ± 0.9, P = 0.024; spleen 17.99 ± 27.8 vs. 13.4 ± 2.6, P = 0.027; kidney, 35.9 ± 59.5 vs. 19.3 ± 4.8, P = 0.025) and also AUC values (right lobe, 13,538 ± 20,020 vs. 8427.3 ± 1557.9, P = 0.026; left lobe 12,304 ± 18,871 vs. 6878.9 ± 1294.3, P = 0.024; spleen, 12,875 ± 17,930 vs. 8263.9 ± 1279.2, P = 0.023; kidney, 24,623 ± 36,025 vs. 13,667 ± 3873.9, P = 0.032). No difference in kinetic parameters was found. No correlations between
severity of clinical signs and imaging-derived parametric data were found among patients
with cirrhosis.
Conclusions
[11C] choline PET/CT may serve as a noninvasive biomarker for patients with cirrhosis.
