Objective To evaluate 3D reconstruction through CT in the measurement of abdominal cavity volume. Methods From January 1, 2019 to December 31, 2019, 61 patients diagnosed as external abdominal hernia were included in this prospective study. Multislice computed tomography (MSCT) was applied to patients scanning, and the images were transferred to post-processing workstation for further analysis. We measured the abdominal cavity volumes using volume rendering (VR) method and diameter rendering (DR) method, and the results were used to test whether there is a correlation between them. In addition, the time required for the measurement was recorded and analyzed. Results In this study, we found that there was no significant difference in the abdominal cavity volumes between these two groups (VR vs. DR = 7857.316 ± 2035.786 cm 3 vs. 7967.268 ± 2925.792 cm 3 , P  > 0.05). Besides, the correlation analysis between the measured values of VR method and DR method showed there was a significant positive correlation ( r  = 0.922, P
