Objectives: To compare speed and accuracy between both the automatic and manual CT liver volumetry and between two radiologist with different long of their medical practice.

Methods: 66 patients with liver metastases of colorectal cancer were included to the study. The analysis of total liver volume and FLRV (future liver remnant volume) was performed using automatic and manual CT volumetry by two different experienced radiologist.

Results: Statistically significantly faster procedure was observed by the automatic CT volumetry in comparison to the manual method (p < 0.0001). No statistically significantly different value of detected liver volumes were found by manual and automatic method (p = 0.552) neither the two performing radiologist (p = 0.612 from time and p = 0.909 from volumes).

Conclusion: The automatic CT volumetry is optimal method for the measurement of the liver. The results are accurate and the speed of analysis is significantly higher in comparison to the manual CT volumetry.

Keywords: CT volumetry, liver, metastases, future liver remnant volume
