摘要/Abstract

摘要： 为研究多层螺旋CT多平面重建在胃肠道淋巴瘤诊断中的应用价值及检测结果与临床分期的相关性，本次研究筛选我院2016年1月~2019年6月收治的50例经病理学检查证实的胃肠道淋巴瘤患者为观察组，另选同期50例非胃肠道淋巴瘤患者为对照组，均实施多层螺旋CT多平面重建，对比两组及观察组内不同组织类型、不同临床分期患者CT重建参数（图像客观噪声、信噪比）的差异，利用Pearson相关性分析法对CT重建参数与胃肠道淋巴瘤临床分期的相关性进行检验。病理学检查证实，50例胃肠道淋巴瘤患者中有弥漫性大B细胞淋巴瘤25例、黏膜相关淋巴瘤19例、小B细胞淋巴瘤4例、套细胞淋巴瘤2例，与多层螺旋CT多平面重建符合率差异无统计学意义（P>0.05）。观察组图像客观噪声低于对照组，信噪比高于对照组，差异有统计学意义（P<0.05）。观察组内不同组织类型患者、不同临床分期患者CT重建参数差异有统计学意义（P<0.05）。Pearson相关性分析结果提示，多层螺旋CT多平面重建参数中图像客观噪声与胃肠道淋巴瘤临床分期呈负向相关性（r=-0.74，P<0.05），信噪比与胃肠道淋巴瘤临床分期呈正相关性（r=0.71，P<0.05）。据此可得，在胃肠道淋巴瘤诊断中多层螺旋CT多平面重建取得的效果更佳且CT重建参数与临床分期密切相关，对于辨别组织类型和判断临床分期具有重要参照价值，值得推广。

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
