Abstract

Abstract: In order to study the application value of multiplanar reconstruction of MSCT in the diagnosis of gastrointestinal lymphoma and the correlation between the detection results and clinical stages, 50 cases of gastrointestinal lymphoma confirmed by pathological examination in our hospital from January 2016 to June 2019 were selected as the observation group, and 50 cases of non-gastrointestinal lymphoma were selected as the control group, all of them were implemented with MSCT multiplanar reconstruction. We compared the difference of CT reconstruction parameters (image objective noise, signal-to-noise ratio) between the two groups. We also compared the difference of CT reconstruction parameters of different tissue types and clinical stages in observation group. And we tested the correlation between CT reconstruction parameters and clinical stages of gastrointestinal lymphoma by Pearson correlation analysis. Pathological examination showed that there were 25 cases of diffuse large B-cell lymphoma, 19 cases of mucosa related lymphoma, 4 cases of small B-cell lymphoma and 2 cases of mantle cell lymphoma in 50 cases of gastrointestinal lymphoma. There was no significant difference in the coincidence rate of pathological results and multiplanar reconstruction results of MSCT (P>0.05). The objective noise of the image in the observation group was lower than that in the control group, and the signal-to-noise ratio was higher than that in the control group (P<0.05). There was significant difference in CT reconstruction parameters of different tissue types and clinical stages in the observation group (P<0.05). The results of Pearson correlation analysis showed that the image objective noise in multiplanar reconstruction parameters of MSCT was negatively correlated with the clinical stage of gastrointestinal lymphoma (r=-0.74, P< 0.05), and the signal-to-noise ratio was positively correlated with the clinical stage of gastrointestinal lymphoma (r=0.71, P<0.05). Therefore, this paper showed that in the diagnosis of gastrointestinal lymphoma, multi-slice spiral CT multiplanar reconstruction has a better effect, and the CT reconstruction parameters are closely related to the clinical stage, which has an important reference value for the identification of tissue type and clinical stage.

Key words: gastrointestinal lymphoma, multiplanar reconstruction of multi-slice spiral CT, CT reconstruction parameters, clinical stage
