多层螺旋CT多平面重建技术在胃肠道淋巴瘤鉴别诊断中的应用

Application of multi-slice spiral CT multi-planar reconstruction technique in the differential diagnosis of gastrointestinal lymphoma

目的:探讨多层螺旋CT多平面重建技术在胃肠道淋巴瘤鉴别诊断中的应用价值。方法:采用回顾性研究方法,2012年2月到2016年1月选择在我院诊治的胃肠道淋巴瘤患者72例作为观察组,同时选择经病理确诊的消化道其他类型肿瘤72例作为对照组,两组都给予常规多层螺旋CT扫描与多平面重建技术分析,判断鉴别诊断效果。结果:观察组常规多层螺旋CT扫描的表现特征与对照组对比无明显差异(P>0.05)。观察组与对照组的图像质量评分分别为(4.67±0.15)分和(4.59±0.21)分,两两对比无明显差异(t=-0.451,P>0.05)。观察组的SD与SNR值分别为7.99±1.34和8.56±1.94,对照组分别为8.78±0.99和7.24±0.81,两两对比都有明显差异(P<0.05)。观察组中有2例被误诊为腺瘤与结肠癌,而对照组中有1例被误诊为黏膜相关淋巴瘤。结论:多层螺旋CT在胃肠道淋巴瘤中的应用不仅可以发现病变,而且扫描获取的容积数据资料,可以通过多平面重建技术获得更丰富的信息,有利于进行临床诊断与鉴别。

Objective： To explore the application values of multi-slice spiral CT multi-planar reconstruction technique in the differential diagnosis of gastrointestinal lymphoma.Methods： Using a retrospective study method,From February 2012 to January 2016,72 gastrointestinal lymphoma patients in our hospital for diagnosis and treatment were selected as the observation group,and the 72 pathological diagnosis of digestive tract of other types of cancer patients were selected as the control group.Two groups were given conventional multislice spiral CT scanning and multiplanar reconstruction analysis,and the differential diagnosis value was given the judgment.Results： There was no significant difference compared between the observation group and the control group in the performance characteristics of multi-slice spiral CT scanning（p〉0.05）.The image quality scores in the observation group and the control group were（4.67 ± 0.15） points and（4.59 ± 0.21） points which were not significantly different（t =-0.451,p〉0.05）.The values of SD and SNR in the observation group were 7.99 ± 1.34 and 8.56 ± 1.94 respectively,and the control group were 8.78 ± 0.99 and 7.24 ± 0.81 respectively which were all significantly different（p〈0.05）.In the observation group,there 2 patients misdiagnosed as adenoma and colon cancer,and 1 patient in the control group were misdiagnosed as mucosa associated lymphoma.Conclusion： The application of multi-slice spiral CT in gastrointestinal lymphoma can not only find lesions,but can obtain more abundant information through multi-planar reconstruction technique,which is helpful to clinical diagnosis and differential diagnosis.
