【摘要】：目的比较弥散加权成像(DWI)与对比增强成像诊断中老年小肠疾病患者的效果。方法选择2015年2月至2016年7月该院80例中老年人患者因肠病行磁共振成像,对其DWI与对比增强成像进行分析比较。结果对所有小肠疾病的诊断,对比增强成像的准确率明显高于DWI(P0.05)。诊断肠道肿瘤方面,对比增强成像的诊断灵敏度、诊断特异度、阳性预测值、阴性预测值及准确率明显高于DWI(P0.05);诊断炎性肠病方面,对比增强成像与DWI诊断灵敏度、诊断特异度、阳性预测值、阴性预测值及准确率差异无统计学意义(P0.05)。结论对中老年肠道肿瘤性病变诊断,对比增强成像较DWI诊断率高;二者诊断炎性肠病方面无明显差别。
[Abstract]:Objective to compare the effectiveness of diffusion-weighted imaging (DWI) and contrast enhanced imaging in the diagnosis of middle and old patients with small bowel disease. Methods from February 2015 to July 2016, 80 elderly patients with intestinal diseases were studied by magnetic resonance imaging (MRI), and their DWI and contrast enhanced imaging were compared. Results the accuracy of contrast-enhanced imaging was significantly higher than that of DWI P0.05 in the diagnosis of all small bowel diseases. In the diagnosis of intestinal tumors, the diagnostic sensitivity, diagnostic specificity, positive predictive value, negative predictive value and accuracy of contrast-enhanced imaging were significantly higher than that of DWII-P0.05.The diagnostic sensitivity of contrast-enhanced imaging and DWI was higher than that of DWI. There was no significant difference in positive predictive value, negative predictive value and accuracy rate (P 0.05). Conclusion the diagnostic rate of contrast-enhanced imaging is higher than that of DWI in the diagnosis of intestinal neoplasms in middle and old age, and there is no significant difference in the diagnosis of inflammatory bowel disease between them.
