Abstract:

Objective

To explore the diagnostic value of CT and ultrasound in acute pancreatitis patients complicated with fatty liver.

Methods

A retrospective analysis was performed on clinical and imaging data of 100 patients with acute pancreatitis in Yilong County People's Hospital between May 2021 and July 2023. All patients underwent CT and color Doppler ultrasound examinations. The imaging characteristics of acute pancreatitis and the detection of fatty liver of the two detection methods were analyzed.The detection of fatty liver by CT and color ultrasound was analyzed by Kappa analysis.

Results

Among 100 patients with acute pancreatitis，there were 67 cases with fatty liver and 33 cases without. CT examination showed that there were 91 cases （91.00%） with increased CT volume of pancreas，86 cases （86.00%） with decreased density and 40 cases （40.00%） with decreased CT density of liver [including 19 cases （47.50%）with diffuse decrease and 21 cases （52.50%） with limited decrease]. The ultrasound examination showed that there was pancreas enlargement to different extent，including 48 cases （48.00%） with blurred edge and decreased echo，52 cases （52.00%） with blurred contour and uneven echo. There were 32 cases （32.00%）with non-obvious hepatic vessels and strong echo，and 18 cases （18.00%） with uneven ultrasonic texture of liver. CT showed that there were 40 cases with fatty liver，with Kappa consistency of 0.650. Color ultrasound showed that there were 50 cases with fatty liver，with Kappa consistency of 0.520. There were no statistically significant differences in accuracy，sensitivity and specificity between CT and color ultrasound in the diagnosis of fatty liver （65.00%，59.70%，75.80% vs 77.00%，74.60%，81.80%，P＞0.05）.

Conclusion

There is few difference between CT and color Doppler ultrasound in diagnosis of patients with acute pancreatitis，and both have high diagnostic value in fatty liver.
