摘　　要：目的探讨以低浓度钆喷酸葡胺(Gd-DTPA注射液)作为阳性造影剂进行MRI检查对诊断十二指肠憩室的可行性。方法对常规检查疑似十二指肠憩室患者进行MRI薄层及口服低浓度造影剂MRI薄层检查。结果 55例患者65个憩室被检出,46例位于十二指肠降部,9例位于十二指肠水平部。MRI薄层检查59个憩室内含气液平或气体,6个憩室仅表现为十二指肠壁外囊袋状影;口服低浓度造影剂MRI薄层检查65个憩室内均充填造影剂,重建图像清晰显示憩室颈部及憩室腔形态。结论口服低浓度造影剂MRI薄层检查有助于十二指肠憩室的明确诊断,MRI三维后处理可以与上消化道钡餐检查相媲美。口服低浓度造影剂MRI薄层检查可以作为十二指肠憩室诊断有疑问时的有力补充。Objective To investigate the feasibility of using the gadolinium-DTPA（GdDTPA injection） at low concentration as a positive MRI contrast agents to diagnose the duodenal diverticulum. Methods Thin layer MRI scans with and without oral contrast agents were performed in the patients with suspected duodenal diverticula. ResultsAmong 55 patients, 46 cases were found in the descending duodenum, 9 were found in the horizontal part of duodenum. Sixty-five diverticula were detected in all the patients. Routinely thin layer MRI scans showed that 59 diverticulum contains gas-liquid borderline or gas, 6 diverticulum just exhibited as the pocket hernia shadow in duodenal wall. Thin layer MRI scans with oral contrast agent showed all 65 diverticula were filled with contrast agent. Reconstructed images displayed the cervical part and cavity of the diverticula clearly. Conclusion MRI thin layer scan with oral low concentration of contrast agent can help to the diagnosis of duodenal diverticulum. Three-dimensional reconstruction was comparable with upper gastrointestinal barium meal examination. It can be used as a powerful supplement for the suspicious diverticula diagnosis.
