CT小肠造影研究进展

Research Progress of CT Enterography

小肠结构复杂,普通X线钡剂小肠造影及CT平扫等对小肠平坦型及微小隆起型等病变检出率低。CT小肠造影(CTE)技术因其多平面重组、最大密度投影和容积再现等强大的后处理功能逐渐成为近年国内外学者研究的热点之一,它可与小肠镜、胶囊内镜等相互补充,明显提高小肠疾病的检出率。CTE分为插管法和口服法两种,目前国内以口服法为主,国外以插管法使用较多。插管法对受检者而言相对痛苦,而口服法对小肠的充盈程度要求高,临床较难掌控。因此,两者在检查方法方面仍需进一步探索。

The small intestine＇s structure is complex, and the detection rate of ordinary X-ray barium small bowel ima-ging and CT scan of the small intestine smooth type and tiny uplift type lesion is low. CT enterography（CTE） because of itsmultiple planar reconstruction, maximum density projection, volume rendering technique, and other powerful post-process-ing function, has gradually become one of hot topics in the study of domestic and foreign scholars in recent years, whih cancomplement each other with capsule endoscopy and enteroscopy etc,thus improve the detection rate of small bowel diseasesignificantly. CTE includes intubation and oral method, and the oral method is mostly adopted in China currently, while intu-bation method is widely used abroad. Intubation is painful for the subjects, and oral method requires high filling degree of thesmall intestine,which is difficult to control in clinical, therefore further exploration is still needed for both methods.
