摘要
目的：探讨多层螺旋CT小肠造影（MSCTE）对小肠病变的诊断价值。方法：对36例疑有小肠病变的患者行螺旋CT平扫及增强检查。检查前清洁肠道，肌注盐酸654-2 10~20mg以减少肠蠕动，口服足量等渗甘露醇水对比剂充盈肠管，结合多平面重组（MPR）或最大密度投影（MIP）观察。结果：经病理证实，病变组共20例：小肠肿瘤14例，其中腺癌4例，间质瘤6例，淋巴瘤2例，腺瘤和类癌各1例；Crohn’s病3例；术后粘连性肠梗阻3例。余为正常组。结论：多层螺旋CT小肠造影双期增强扫描结合重建技术对小肠病变的定位、定性及肿瘤分期有较高临床价值。
Abstract
Objective: To investigate the value of multi-slice CT enterography(MSCTE) in intestinal diseases. Methods: Helical CT scans were performed in 36 patients before and after infusion of contrast medium. Before CT examination, all patients were injected 10~20mg 654-2 to minimize bowel movement then took administered iso-osmotic mannitol to fill the bowl. Multiplanar reformation(MPR), maximum intensity projection(MIP) were carried out. Results: Among 14 cases of intestinal neoplasms, there were 4 cases of adenocarcinoma, 6 cases of stromal tumor, 2 cases of lymphoma, 1 case of adenoma and 1 case of carcinoid tumor, 3 cases of Crohn’s diseases, and 3 cases of postoperative adhesion. The others were normal. Conclusion: MSCTE using biphasic enhancing and 3D-image reconstruction techniques was valuable for intestinal diseases.
