摘要
目的探讨口服等渗甘露醇多层螺旋CT小肠造影(MSCTE)及体位选择对小肠病变诊断的应用价值。方法 70例受检者口服2.5%等渗甘露醇2000 mL,检查前分4次口服,400～500 mL/次,充分充盈胃和十二指肠。随机分为2组,35例采取仰卧位,35例采取俯卧位。平扫后行增强扫描,通过多平面重建,观察和测量肠管宽度、肠壁厚度、肠腔黏膜,及肠管外病变、肠系膜血管、腹腔淋巴结,并对各组测量数据及评价结果进行分析。结果 62例小肠充盈满意的患者肠管内外病变、肠系膜血管、腹腔淋巴结二组都显示满意,肠管分布、肠腔黏膜的显示,俯卧位优于仰卧位。结论口服等渗甘露醇多层螺旋CT小肠造影俯卧位更有助于对小肠疾病的诊断。
Objective To investigate the value of prone multislice spiral CT enterography（MSCTE） with isosmotic mannitol as oral contrast in the treatment of bowel diseases. Methods 70 patients diagnosed with bowel diseases received oral administration of 500 ml isosmotic mannitol（2.5%） for four times（2000 mL in total） as intraluaminal contrast media before scanning. They were randomly divided into two groups and received plain and contrast-enhanced CT scanning examination,with 35 patients examined in supine position（supine group） and 35 in prone position（prone group）. The width of intestines,intestinal wall thickness, intestinal mucosa, lesions beyond the intestines, mesenteric vascular and celiac lymph node were observed or measured through multiplanar reconstruction（MPR）, and the data were then analyzed. Results 62 cases in total had relative good image quality, wherein lesions beyond the intestines, mesenteric vascular and celiac lymph node were observed with a good quality at the same level in each group while intestinal details and mucosa were better displayed in images of those from prone group than those from supine group. Conclusions MSCTE performed in prone position is better for the observation and diagnose of intestinal lesions.
