【摘要】：目的探讨MRI在小儿肠道疾病中的诊断价值。方法回顾性分析17例肠道疾病患儿的MRI资料,10例行MRI常规扫描,7例患儿行MR肠动描记法(MRE)扫描。结果图像分析:4例患儿由于肠梗阻未口服肠道对比剂,均明确显示梗阻部位及梗阻原因,病因诊断敏感性100%(4/4),但远端小肠、结肠扩张度不满意;5例耐受度差、1例未足量口服肠道对比剂患儿均有不同程度肠段扩张度不满意;7例口服足量肠道对比剂患儿肠管扩张度良好。MRI表现:肠内征象包括肠壁增厚10例、黏膜强化7例、跳跃征1例、管腔扩张6例、管腔狭窄9例、瘘管1例;肠外征象包括肠系膜血管水肿充血2例、肠周炎性渗出4例、脓肿2例、淋巴结增大3例、腹水5例。结论常规MRI扫描对小儿先天性肠道疾病诊断安全、有效,MRE检查仅适合较大年龄组患儿,多序列联合技术可对小儿肠道疾病诊断提供更多信息,为指导临床治疗方案的选择提供重要依据。
[Abstract]:Objective to investigate the diagnostic value of MRI in children with intestinal diseases.Methods the MRI data of 17 children with intestinal diseases were analyzed retrospectively. Routine MRI scanning was performed in 10 cases and MRE was performed in 7 cases.Results the image analysis showed clearly the location of obstruction and the cause of obstruction. The sensitivity of etiological diagnosis was 100 / 4 / 4, but the distal small intestine.Colonic dilatation was unsatisfactory in 5 patients with poor tolerance and 1 child without adequate oral intestinal contrast agent had different degree of intestinal dilatation. MRI findings of intestinal tract dilatation were good in 7 patients with oral adequate intestinal contrast agent.Including 10 cases of intestinal wall thickening,Mucosal enhancement in 7 cases, jumping sign in 1 case, lumen dilatation in 6 cases, lumen stenosis in 9 cases, fistula in 1 case, extraintestinal signs included mesenteric vascular edema in 2 cases, periintestinal inflammatory exudation in 4 cases, abscess in 2 cases, lymph node enlargement in 3 cases, ascites in 5 cases.Conclusion conventional MRI scan is safe in the diagnosis of congenital intestinal diseases in children, and it is only suitable for children in older age group. Multi-sequence combined technique can provide more information for the diagnosis of intestinal diseases in children.To provide an important basis for guiding the selection of clinical treatment plan.
