Application Research Of Magnetic Resonance Hydrography In The Intestinal Disease

[Objective]Comparative study of mixed solution and 2.5%osmotic mannitol as oral contrast medium of MRI inspection of intestine;Research the value of Magnetic resonance hydrography in application and diagnosis of intestinal disease.[Materials and methods]1 Research of contrast medium 20 voluntees were derided into 2 groups,drunk mixed solution(every 1000ml solution consists of 20% osmotic mannitol 250ml,5%glucose saline 500ml and water 250ml)and 2.5% osmotic mannitol respectively.Compared the 2 groups infects from expantion degree, imaging quality and adverse reaction.2 Clinical application Seventy-three patiens with suspect of intestine disease were studied by MRI.Observed the MRI manifestations of the different disease.Evaluate the display effect of different MR sequences.[Results]1 Research of contrast medium There were no significant difference between two groups in mean expantion degree and adverse reaction(p＞0.05),mixed solution was superior to 2.5%osmotic mannitol in expantion degree and imaging quality of the fourth,fifth,sixth group small intestine.As oral contrast medium of MRI inspection of intestine,mixed solution of osmotic mannitol was superior to 2.5% osmotic mannitol in expantion degree and imaging quality,was an ideal oral contrast medium.2 Clinical application In 73 patients,45 cases were pathologically proved. 39 cases' MRI diagnosis is correct,diagnostic accordance rate is 86.7%;In the last 28 cases,there are 23 cases' diagnosis accordance with clinical manifestation and other inspections,diagnostic accordance rate is 82.1%.There were no significant difference between different sequences of MRI in showing mass,but have difference in showing mural abnormalities,bowel constriction,extra-lumiinal compression and mucosal lesion.[Conelution]1 Osmotic mannitol mixed solution as an oral contrast medium of MRI inspection of intestine,can enhance the sign of small intestinal tract,increase the contrast of the intestinal tract and the surrounding tissue,fully fill the enteric cavity, and low price,has no obvious adverse reaction,so it can be as an ideal oral contrast medium for Magnetic resonance hydrography in application and diagnosis of intestinal disease.2 Magnetic resonance hydrography using osmotic mannitol mixed solution as an oral contrast medium,can clear display small bowel and colorectal wall,enteric cavity and periphery structure.This method can be used in the diagnosis of intestinal disease.3 Magnetic resonance hydrography is valuable in localization diagnosis of intestinal disease,it has the advantages of non-invasive,non-ion radiation,convenient and high precision.Especially has advantages in the diagnosis of intestinal disease,intestinal tumor,and for the patients who unsuitable take the barium meal and gastroenterological endoscope.4 Magnetic resonance hydrography in a diagnosis of intestinal disease remains the research stage.The further experience should be accumulated and the effect observed.
