胰腺CT:水与1.5%泛影葡胺充盈胃肠道对胰腺显示的比较

122例胰腺CT随机分成四组,分别在用或不用654—2的情况下口服水或1.5%泛影葡胺。结果表明:在用或不用654—2的情况下水对胰头显示优片率分别为87.1%,53.3%,两者有极显著性差别((P<0.01)。1.5%泛影葡胺对胰头显示优片率分别为77.4%,46.7%,两者有显著性差别(0.05

Pancreatic CT: Comparative Study of Pancreatic Visualizing by Opacificating Gastrointestine with Water and 1.5% USP

122 patients who had pancreatic CT were randomly derided into four groups. In group one, there are 31 patients with oral water and intravenous 654—2. In group two, there are 30 patients with oral water alone. In group three,there are 31 patients with oral 1.5% Diatrizoate meglumine (USP) and intravenous 654—2. In group four,there are 30 patients with oral 1.5% USP alone. In order to avoid the affect of body type, the thickness of subcutaneous fat at the back of the body where the pancres be vasualized clearly was measured. The results demonstrated that the difference among the four groups had not statistical signifiance (P<0.05),It showed that body type didn't affect the experimental results. In conclusion: we recommend that water may be used as an oral contrast medium for pancreatic CT. The advantage of the water is as follows:patients can accept it easily,usage in safety and convenience. Pancreatic visualizing with oral water was similar to that with oral 1.5% USP. Moreover the artifacts produced by water was less than that by 1.5% USP. 654—2 was effective to visualize the pancreatic head but it was not so ideal for the body and the tail.
