Abstract：Objective To compare the diagnostic ability of X-ray ,CT ,MRI and DSA in gastroenteropathy .Methods 94 cases with gastroenteropathies were included in this study who had been diagnosed by radiology from Jan 2012 to Dec 2012 .In these cases ,males were 52 aged from 2~81 years with median age 52 years ,and females were 42 aged from 8~87 years with median age 59 years .Radiology examination methods were X-ray air-Ba double contrast radiography ,CT plain scan ,CT contrast enchancement (CT-CE) scan ,CT angiography (CTA) ,MRI and digital substraction angiography (DSA) .Took digestive endoscopy examination and (or) operation-pathological diagnosis obtained by following-up as the reference standard to evaluate the diagnostical capability of imaging methods in gastroenteropathy .Results In 94 cases , 14 received X-ray air-Ba double contrast radiography ,among them ,12 directly got identify diagnosis ,the other 2 got iden-tify diagnosis by CT in further examination ;68 received CT ,among them ,7 directly got identify diagnosis by CT plain scan ,in further examination performed for identify diagnosis ,57 by CT-CE ,and in next further examination ,1 by X-ray air-Ba double contrast radiography ,1 by MRI ,1 by DSA and 1 by operation research ;11 received CTA ,among them ,8 directly got identify diagnosis and 3 by DSA in further examination .Only 1 case received MRI but got no identify diagno-sis ,further CT examination help to get diagnosis .Conclusion CT relatively has higher diagnostic value compraring with X-ray ,M RI and DSA in gastroenteropathy ,but combination of multiple imaging methods could make up the limitation of single method ,significantly improving the diagnostic capability in gastroenteropathy .
