摘　　要：目的探讨口服等渗甘露醇法低剂量多层螺旋CT小肠造影(Multislice computed tomography enterography,MSCTE)对小肠疾病的诊断价值。方法对62例临床怀疑小肠疾病患者口服2.5%等渗甘露醇溶液及肌注山莨菪碱后随机分组分别行常规剂量和低剂量MSCTE检查,将诊断结果与手术病理、内镜病理或临床随访结果进行对照,评估常规剂量和低剂量MSCTE对小肠疾病的诊断价值并比较二者诊断准确率有无差异。结果经病理及随访结果证实小肠疾病57例,常规剂量MSCTE诊断敏感性89.28%、特异性80.00%、准确率87.87%,低剂量MSCTE诊断敏感性88.46%、特异性100.00%、准确率89.65%。两种检查方法诊断准确率有无统计学差异(χ~2=3.27,P=0.574)。结论口服等渗甘露醇法低剂量MSCTE在多种小肠疾病有较高的诊断价值。Objective To evaluate the diagnostic performance of low-dose multislice computed tomography enterography(MSCTE) with isosmotic mannitol as oral contrust in small intestinal diseases. Methods 62 patients suspected of various kinds of small intestinal diseases were randomly allocated to be examined with traditional-dose and low-dose MSTCE after oral administration of isosmotic mannitol(2.5%) and injection of raceanisodamine hydrochloride. The MSCTE findings were analyzed, on which diagnosis were made and compared with those confirmed by pathology and follow-up visit. Results 57 patients were confirmed to have small intestinal diseases. The sensitivity, specificity and accuracy of traditional-dose and low-dose MSTCE were 89.28%, 80.00%, 87.87% and 88.46%, 100.00%, 89.65% respectively.No statistical difference was found between the diagnostic values of these two methods(χ2=3.27,P=0.574). Conclusion Low-dose MSCTE with isosmotic mannitol as oral contrast has relatively high diagnostic value in various kinds of small intestinal lesions.
