Abstract:Objective: To study the clinical value of multislice spiral CT multiplane reconstruction in the diagnosis of appendicitis mucinous tumor. Methods: A retrospective analysis was conducted, and 60 patients with mucinous tumor of the appendix admitted from January 2017 to January 2022 were selected as the observation subjects. All patients received multislice spiral CT multiplane reconstruction examination and abdominal CT plain scan examination. The diagnostic accuracy of the two examination methods was compared, and the manifestations of multislice spiral CT multiplane reconstruction were analyzed. Results: The accuracy of multislice spiral CT multiplane reconstruction was 98. 33% in 60 patients with mucinous tumor of the appendix. The accuracy of abdominal CT plain scan in 60 patients with appendiceal mucinous tumor was 85. 00%. The accuracy of multislice spiral CT in the diagnosis of appendiceal mucinous tumor was significantly higher than that of abdominal CT, and the difference was statistically significant (P<0. 05). Multislice spiral CT multi-plane reconstruction showed that the tumor lesions in 25 patients were oval, small at the bottom and mouth, and enlarged in the middle. In 13 patients, the tumor lesions were aubergine-like, enlarged at the bottom and middle, and small at the mouth. In 13 patients, the tumor lesions were peanut-shaped, the cystic mass was overall enlarged, and the expansion at the bottom and mouth was more significant than that in the middle, and the tumor showed bunched waist sign. The tumor lesions of 9 patients were irregular and long tubular. After multi-plane reconstruction, not only the shape of the tumor can be clearly displayed, but also the three directions (upper and lower diameters, left and right diameters, front and rear diameters) can be measured, so as to measure the stenosis and enlargement of different shapes of the tumor, thus improving the accuracy of the measurement of the tumor size. Conclusion: The application of multi-slice spiral CT multi-plane reconstruction post-processing technology in the diagnosis of mucinous tumors of the appendix has significant effects, which can effectively improve the diagnostic accuracy. Moreover, this technology has certain characteristics in the morphologic manifestations of tumors, and can provide reference for the formulation of clinical treatment plan.
