Abstract: Objective The aim of this study was to investigate the value of total liver volume (TLV)/spleen volume (SV) ratio by multislice CT calculation in diagnosis ofpatients with liver cirrhosis (LC). Methods 138 cirrhotic patients and 130 patients with benign liver diseases or healthy persons were admitted to our hospital between October 2016 and October 2019, and all underwent dynamic contrast-enhanced multi-slice spiral CT scan. The TLV, right liver volume (RV), left inner lobe volume(LMV), left outer lobe volume (LLV), cauda lobe volume (CV), SV as well as TLV/RV ratio, TLV/LMV ratio, TLV/LLV ratio, TLV/CV ratio and TLV/SV ratio were calculated by software. Results The TLV, RV and LMV of liver in patients with LC were (1078.2±315.7) cm³, (543.8±186.5) cm³ and (163.6±73.7) cm³, significantly smaller than [(1470.4±199.7) cm³, (933.3±174.1) cm³ and (216.2±40.1) cm³, respectively, P<0.05], while the LLV and SV were (327.8±121.9) cm³ and (863.4±396.8) cm³, both significantly larger than [(275.9±65.7) cm³ and (256.3±81.7) cm³, respectively,P<0.05] in the control; the TLV / RV ratio in patients with LC was 2.0±0.9, significantly higher than [1.6±0.7, P<0.05], while the TLV / LLV ratio, TLV / CV ratio and TLV / SV ratio were (3.3±1.5), (25.3±12.4) and (1.3±0.6), all significantly lower than [(5.3±2.5),( 32.8±16.1) and (5.7±2.4), respectively, P<0.05] in the control; there were no significant differences in CV and TLV/LMV ratio between the two groups (P>0.05). Conclusion The calculation of TLV/SV by multislice spiral CT scan might help diagnose LC in clinical practice.
