摘　　要：目的探讨CT小肠造影(CT enterography,CTE)在嗜酸性粒细胞性胃肠炎(Eosinophilic gastroenteritis,EG)的诊断和鉴别诊断中的临床价值,并初步尝试通过联合虚拟3D打印技术观察病变,分析该检查方法在判断EG肠壁受累程度中的价值。方法选取11例诊断为EG患者的临床及影像学资料。从肠壁累及程度、肠系膜血管、淋巴结等比较分析CT平扫和CTE检查的表现,并使用Mimics软件进行3D打印虚拟建模。结果CT平扫不能区分EG患者的肠壁累及层次。CTE检出胃肠道黏膜受累11例,胃肠道肌肉受累10例,浆膜受累7例,其中全层受累6例。3D重建和打印技术也可以更加整体的展示病变。结论与常规CT平扫相比,CTE更能准确判断EG肠壁受累程度。通过Mimics软件实现的三维重建技术可以更好地显示病变,有利于医学诊断和手术方案的制定和教学的应用。Objective To analyze the CT enterography(CTE)of eosinophilic gastroenteritis(EG),to study the clinical value of CTE in the diagnosis and differential diagnosis of EG,and to preliminarily try to observe the lesions through 3D reconstruction technology.Methods The clinical and imaging data of patients with EG diagnosed in our hospital from January 2015 to December 2020 were retrospectively analyzed.The findings of CT plain scans and CTEs were compared in terms of degree of intestinal wall involvement,mesenteric vessels,lymph nodes,and Mimics software was used for three-dimensional modeling.Results The CT plain scan could not distinguish the layers involved in EG.CTE detected 11 cases of gastrointestinal mucosa involvement,10 cases of gastrointestinal muscle involvement and 7 cases of serosa involvement,among which 6 cases showed fullthickness involvement.3D reconstruction and printing increased the overall and local observation of lesions.Conclusion Compared with conventional plain CT,CTE can more accurately determine the degree of intestinal wall involvement in EG.The 3D reconstruction technology realized by Mimics software can better display the lesions,which is helpful to the planning of medical diagnosis and medical operation planning and the application of teaching.
