Abstract Objective: To discuss the difference of gallbladder wall thickness in liver cirrhosis with gallbladder fossa fluid accumulation on ultrasound scanning and CT multi-plane reconstruction images. Materials and Methods: Ultrasound scanning and multi-slice CT were performed in 39 patients who had gallbladder fossa fluid accumulation with liver cirrhosis, all cases were under fasting condition. Gallbladder wall thickness was measured both on ultrasonographic and multi-slice CT 3D reconstruction images. The scatter diagram was drawn and Pearson correlation analysis and paired sample t test comparison of gallbladder wall thickness were also carried out. Result: Compared with multi-plane CT reconstruction, ①Ultrasound missed the diagnosis of gallbladder fossa fluid accumulation in 31 cases, over estimation of gallbladder wall thickness in 16 cases, and under estimation of the thickness in 2 cases. ②The correlation coefficient of ultrasound detection of gallbladder wall thickness with CT detection was 0.648(P<0.000). ③Ultrasound detection of gallbladder wall thickness was(6.2±2.6)mm, CT detection of gallbladder wall thickness was (4.5±2.0)mm, there was statistical significance(t=4.465, P<0.000). The coefficient of variation was 0.42 and 0.44 respectively. Conclusion: Multi-slice CT scanning is more sensitive in the detection of limited gallbladder fossa fluid accumulation than ultrasound. It can accurately differentiate gallbladder fossa fluid accumulation with gallbladder wall thickening in liver cirrhosis.
